dart-lang/sdk (dart) ### [`v3.2.2`](https://togithub.com/dart-lang/sdk/compare/3.2.1...3.2.2) [Compare Source](https://togithub.com/dart-lang/sdk/compare/3.2.1...3.2.2) ### [`v3.2.1`](https://togithub.com/dart-lang/sdk/compare/3.2.0...3.2.1) [Compare Source](https://togithub.com/dart-lang/sdk/compare/3.2.0...3.2.1) ### [`v3.2.0`](https://togithub.com/dart-lang/sdk/blob/HEAD/CHANGELOG.md#320) [Compare Source](https://togithub.com/dart-lang/sdk/compare/3.1.5...3.2.0) ##### Language Dart 3.2 adds the following features. To use them, set your package's [SDK constraint][language version] lower bound to 3.2 or greater (`sdk: '^3.2.0'`). [language version]: https://dart.dev/guides/language/evolution - **Private field promotion**: In most circumstances, the types of private final fields can now be promoted by null checks and `is` tests. For example: ```dart class Example { final int? _privateField; Example(this._privateField); f() { if (_privateField != null) { // _privateField has now been promoted; you can use it without // null checking it. int i = _privateField; // OK } } } // Private field promotions also work from outside of the class: f(Example x) { if (x._privateField != null) { int i = x._privateField; // OK } } ``` To ensure soundness, a field is not eligible for field promotion in the following circumstances: - If it's not final (because a non-final field could be changed in between the test and the usage, invalidating the promotion). - If it's overridden elsewhere in the library by a concrete getter or a non-final field (because an access to an overridden field might resolve at runtime to the overriding getter or field). - If it's not private (because a non-private field might be overridden elsewhere in the program). - If it has the same name as a concrete getter or a non-final field in some other unrelated class in the library (because a class elsewhere in the program might extend one of the classes and implement the other, creating an override relationship between them). - If there is a concrete class `C` in the library whose interface contains a getter with the same name, but `C` does not have an implementation of that getter (such unimplemented getters aren't safe for field promotion, because they are implicitly forwarded to `noSuchMethod`, which might not return the same value each time it's called). - **Breaking Change** [#​53167][]: Use a more precise split point for refutable patterns. Previously, in an if-case statement, if flow analysis could prove that the scrutinee expression was guaranteed to throw an exception, it would sometimes fail to propagate type promotions implied by the pattern to the (dead) code that follows. This change makes the type promotion behavior of if-case statements consistent regardless of whether the scrutinee expression throws an exception. No live code is affected by this change, but there is a small chance that the change in types will cause a compile-time error to appear in some dead code in the user's project, where no compile-time error appeared previously. [#​53167]: https://togithub.com/dart-lang/sdk/issues/53167 ##### Libraries ##### `dart:async` - Added `broadcast` parameter to `Stream.empty` constructor. ##### `dart:cli` - **Breaking change** [#​52121][]: - `waitFor` is disabled by default and slated for removal in 3.4. Attempting to call this function will now throw an exception. Users that still depend on `waitFor` can enable it by passing `--enable_deprecated_wait_for` flag to the VM. [#​52121]: https://togithub.com/dart-lang/sdk/issues/52121 ##### `dart:convert` - **Breaking change** [#​52801][]: - Changed return types of `utf8.encode()` and `Utf8Codec.encode()` from `List` to `Uint8List`. [#​52801]: https://togithub.com/dart-lang/sdk/issues/52801 ##### `dart:developer` - Deprecated the `Service.getIsolateID` method. - Added `getIsolateId` method to `Service`. - Added `getObjectId` method to `Service`. ##### `dart:ffi` - Added the `NativeCallable.isolateLocal` constructor. This creates `NativeCallable`s with the same functionality as `Pointer.fromFunction`, except that `NativeCallable` accepts closures. - Added the `NativeCallable.keepIsolateAlive` method, which determines whether the `NativeCallable` keeps the isolate that created it alive. - All `NativeCallable` constructors can now accept closures. Previously `NativeCallable`s had the same restrictions as `Pointer.fromFunction`, and could only create callbacks for static functions. - **Breaking change** \[[#​53311](https://togithub.com/dart-lang/sdk/issues/53311)]\[]: `NativeCallable.nativeFunction` now throws an error if is called after the `NativeCallable` has already been `close`d. Calls to `close` after the first are now ignored. ##### `dart:io` - **Breaking change** [#​53005][]: The headers returned by `HttpClientResponse.headers` and `HttpRequest.headers` no longer include trailing whitespace in their values. - **Breaking change** [#​53227][]: Folded headers values returned by `HttpClientResponse.headers` and `HttpRequest.headers` now have a space inserted at the fold point. [#​53005]: https://dartbug.com/53005 [#​53227]: https://dartbug.com/53227 ##### `dart:isolate` - Added `Isolate.packageConfigSync` and `Isolate.resolvePackageUriSync` APIs. ##### `dart:js_interop` - **Breaking Change on JSNumber.toDart and Object.toJS**: `JSNumber.toDart` is removed in favor of `toDartDouble` and `toDartInt` to make the type explicit. `Object.toJS` is also removed in favor of `Object.toJSBox`. Previously, this function would allow Dart objects to flow into JS unwrapped on the JS backends. Now, there's an explicit wrapper that is added and unwrapped via `JSBoxedDartObject.toDart`. Similarly, `JSExportedDartObject` is renamed to `JSBoxedDartObject` and the extensions `ObjectToJSExportedDartObject` and `JSExportedDartObjectToObject` are renamed to `ObjectToJSBoxedDartObject` and `JSBoxedDartObjectToObject` in order to avoid confusion with `@JSExport`. - **Type parameters in external APIs**: Type parameters must now be bound to a static interop type or one of the `dart:js_interop` types like `JSNumber` when used in an external API. This only affects `dart:js_interop` classes and not `package:js` or other forms of JS interop. - **Subtyping `dart:js_interop` types**: `@staticInterop` types can subtype only `JSObject` and `JSAny` from the set of JS types in `dart:js_interop`. Subtyping other types from `dart:js_interop` would result in confusing type errors before, so this makes it a static error. - **Global context of `dart:js_interop` and `@staticInterop` APIs**: Static interop APIs will now use the same global context as non-static interop instead of `globalThis` to avoid a greater migration. Static interop APIs, either through `dart:js_interop` or the `@staticInterop` annotation, have used JavaScript's `globalThis` as the global context. This is relevant to things like external top-level members or external constructors, as this is the root context we expect those members to reside in. Historically, this was not the case in Dart2JS and DDC. We used either `self` or DDC's `global` in non-static interop APIs with `package:js`. So, static interop APIs will now use one of those global contexts. Functionally, this should matter in only a very small number of cases, like when using older browser versions. `dart:js_interop`'s `globalJSObject` is also renamed to `globalContext` and returns the global context used in the lowerings. - **Breaking Change on Types of `dart:js_interop` External APIs**: External JS interop APIs when using `dart:js_interop` are restricted to a set of allowed types. Namely, this include the primitive types like `String`, JS types from `dart:js_interop`, and other static interop types (either through `@staticInterop` or extension types). - **Breaking Change on `dart:js_interop` `isNull` and `isUndefined`**: `null` and `undefined` can only be discerned in the JS backends. dart2wasm conflates the two values and treats them both as Dart null. Therefore, these two helper methods should not be used on dart2wasm and will throw to avoid potentially erroneous code. - **Breaking Change on `dart:js_interop` `typeofEquals` and `instanceof`**: Both APIs now return a `bool` instead of a `JSBoolean`. `typeofEquals` also now takes in a `String` instead of a `JSString`. - **Breaking Change on `dart:js_interop` `JSAny` and `JSObject`**: These types can only be implemented, and no longer extended, by user `@staticInterop` types. - **Breaking Change on `dart:js_interop` `JSArray.withLength`**: This API now takes in an `int` instead of `JSNumber`. ##### Tools ##### Development JavaScript compiler (DDC) - Applications compiled by DDC will no longer add members to the native JavaScript Object prototype. - **Breaking change for JS interop with Symbols and BigInts**: JavaScript `Symbol`s and `BigInt`s are now associated with their own interceptor and should not be used with `package:js` classes. These types were being intercepted with the assumption that they are a subtype of JavaScript's `Object`, but this is incorrect. This lead to erroneous behavior when using these types as Dart `Object`s. See [#​53106][] for more details. Use `dart:js_interop`'s `JSSymbol` and `JSBigInt` with extension types to interop with these types. ##### Production JavaScript compiler (dart2js) - **Breaking change for JS interop with Symbols and BigInts**: JavaScript `Symbol`s and `BigInt`s are now associated with their own interceptor and should not be used with `package:js` classes. These types were being intercepted with the assumption that they are a subtype of JavaScript's `Object`, but this is incorrect. This lead to erroneous behavior when using these types as Dart `Object`s. See [#​53106][] for more details. Use `dart:js_interop`'s `JSSymbol` and `JSBigInt` with extension types to interop with these types. [#​53106]: https://togithub.com/dart-lang/sdk/issues/53106 ##### Dart command line - The `dart create` command has a new `cli` template to quickly create Dart command-line applications with basic argument parsing capabilities. To learn more about using the template, run `dart help create`. ##### Dart format - Always split enum declarations containing a line comment. - Fix regression in splitting type annotations with library prefixes. - Support `--enable-experiment` command-line option to enable language experiments. ##### DevTools - Incorporated the [2.26.1][devtools-2-26-1], [2.27.0][devtools-2-27-0], and [2.28.1][devtools-2-28-1] releases of DevTools. [devtools-2-26-1]: https://docs.flutter.dev/tools/devtools/release-notes/release-notes-2.26.1 [devtools-2-27-0]: https://docs.flutter.dev/tools/devtools/release-notes/release-notes-2.27.0 [devtools-2-28-1]: https://docs.flutter.dev/tools/devtools/release-notes/release-notes-2.28.1 ##### Linter - Added the experimental [`annotate_redeclares`][annotate_redeclares] lint. - Marked the [`use_build_context_synchronously`][use_build_context_synchronously] lint as stable. [`annotate_redeclares`]: https://dart.dev/lints/annotate_redeclares [`use_build_context_synchronously`]: https://dart.dev/lints/use_build_context_synchronously ##### Pub - New option `dart pub upgrade --tighten` which will update dependencies' lower bounds in pubspec.yaml to match the current version. - The commands `dart pub get`/`add`/`upgrade` will now show if a dependency changed between direct, dev and transitive dependency. - The command `dart pub upgrade` no longer shows unchanged dependencies. ### [`v3.1.5`](https://togithub.com/dart-lang/sdk/blob/HEAD/CHANGELOG.md#315---2023-10-25) [Compare Source](https://togithub.com/dart-lang/sdk/compare/3.1.4...3.1.5) This is a patch release that: - Fixes an issue affecting Dart compiled to JavaScript running in Node.js 21. A change in Node.js 21 affected the Dart Web compiler runtime. This patch release accomodates for those changes (issue [#​53810](https://togithub.com/dart-lang/sdk/issues/53810)). [#​53810]: https://togithub.com/dart-lang/sdk/issues/53810 ### [`v3.1.4`](https://togithub.com/dart-lang/sdk/blob/HEAD/CHANGELOG.md#314---2023-10-18) [Compare Source](https://togithub.com/dart-lang/sdk/compare/3.1.3...3.1.4) This is a patch release that: - Fixes an issue in the Dart VM, users are not being able to see value of variables while debugging code (issue \[[#​53747](https://togithub.com/dart-lang/sdk/issues/53747)]). [#​53654]: https://togithub.com/dart-lang/sdk/issues/53747 ### [`v3.1.3`](https://togithub.com/dart-lang/sdk/blob/HEAD/CHANGELOG.md#313---2023-09-27) [Compare Source](https://togithub.com/dart-lang/sdk/compare/3.1.2...3.1.3) This is a patch release that: - Fixes a bug in dart2js which would cause the compiler to crash when using `@staticInterop` `@anonymous` factory constructors with type parameters (see issue [#​53579] for more details). - The standalone Dart VM now exports symbols only for the Dart_\* embedding API functions, avoiding conflicts with other DSOs loaded into the same process, such as shared libraries loaded through `dart:ffi`, that may have different versions of the same symbols (issue \[[#​53503](https://togithub.com/dart-lang/sdk/issues/53503)]). - Fixes an issue with super slow access to variables while debugging. The fix avoids searching static functions in the imported libraries as references to members are fully resolved by the front-end. (issue [#​53541]) [#​53579]: https://togithub.com/dart-lang/sdk/issues/53579 [#​53267]: https://togithub.com/dart-lang/sdk/issues/53503 [#​53541]: https://togithub.com/dart-lang/sdk/issues/53541 ### [`v3.1.2`](https://togithub.com/dart-lang/sdk/blob/HEAD/CHANGELOG.md#312---2023-09-13) [Compare Source](https://togithub.com/dart-lang/sdk/compare/3.1.1...3.1.2) This is a patch release that: - Fixes a bug in dart2js which crashed the compiler when a typed record pattern was used outside the scope of a function body, such as in a field initializer. For example `final x = { for (var (int a,) in someList) a: a };` (issue [#​53449]) - Fixes an expedient issue of users seeing an unhandled exception pause in the debugger, please [https://github.com/dart-lang/sdk/issues/53450](https://togithub.com/dart-lang/sdk/issues/53450)es/53450 for more details. The fix uses try/catch in lookupAddresses instead of Future error so that we don't see an unhandled exception pause in the debugger (issue [#​53450]) [#​53449]: https://togithub.com/dart-lang/sdk/issues/53449 [#​53450]: https://togithub.com/dart-lang/sdk/issues/53450 ### [`v3.1.1`](https://togithub.com/dart-lang/sdk/blob/HEAD/CHANGELOG.md#311---2023-09-07) [Compare Source](https://togithub.com/dart-lang/sdk/compare/3.1.0...3.1.1) This is a patch release that: - Fixes a bug in the parser which prevented a record pattern from containing a nested record pattern, where the nested record pattern uses record destructuring shorthand syntax, for example `final ((:a, :b), c) = record;` (issue [#​53352]). [#​53352]: https://togithub.com/dart-lang/sdk/issues/53352 ### [`v3.1.0`](https://togithub.com/dart-lang/sdk/blob/HEAD/CHANGELOG.md#310---2023-08-16) [Compare Source](https://togithub.com/dart-lang/sdk/compare/3.0.7...3.1.0) ##### Libraries ##### `dart:async` - **Breaking change** [#​52334][]: - Added the `interface` modifier to purely abstract classes: `MultiStreamController`, `StreamConsumer`, `StreamIterator` and `StreamTransformer`. As a result, these types can only be implemented, not extended or mixed in. [#​52334]: https://togithub.com/dart-lang/sdk/issues/52334 ##### `dart:core` - `Uri.base` on native platforms now respects `IOOverrides` overriding current directory ([#​39796][]). [#​39796]: https://togithub.com/dart-lang/sdk/issues/39796 ##### `dart:ffi` - Added the `NativeCallable` class, which can be used to create callbacks that allow native code to call into Dart code from any thread. See `NativeCallable.listener`. In future releases, `NativeCallable` will be updated with more functionality, and will become the recommended way of creating native callbacks for all use cases, replacing `Pointer.fromFunction`. ##### `dart:io` - **Breaking change** [#​51486][]: - Added `sameSite` to the `Cookie` class. - Added class `SameSite`. - **Breaking change** [#​52027][]: `FileSystemEvent` is [`sealed`](https://dart.dev/language/class-modifiers#sealed). This means that `FileSystemEvent` cannot be extended or implemented. - Added a deprecation warning when `Platform` is instantiated. - Added `Platform.lineTerminator` which exposes the character or characters that the operating system uses to separate lines of text, e.g., `"\r\n"` on Windows. [#​51486]: https://togithub.com/dart-lang/sdk/issues/51486 [#​52027]: https://togithub.com/dart-lang/sdk/issues/52027 ##### `dart:js_interop` - **Object literal constructors**: `ObjectLiteral` is removed from `dart:js_interop`. It's no longer needed in order to declare an object literal constructor with inline classes. As long as an external constructor has at least one named parameter, it'll be treated as an object literal constructor. If you want to create an object literal with no named members, use `{}.jsify()`. ##### Other libraries ##### `package:js` - **Breaking change to `@staticInterop` and `external` extension members**: `external` `@staticInterop` members and `external` extension members can no longer be used as tear-offs. Declare a closure or a non-`external` method that calls these members, and use that instead. - **Breaking change to `@staticInterop` and `external` extension members**: `external` `@staticInterop` members and `external` extension members will generate slightly different JS code for methods that have optional parameters. Whereas before, the JS code passed in the default value for missing optionals, it will now pass in only the provided members. This aligns with how JS parameters work, where omitted parameters are actually omitted. For example, calling `external void foo([int a, int b])` as `foo(0)` will now result in `foo(0)`, and not `foo(0, null)`. ##### Tools ##### DevTools - Incorporated the [2.24.0][devtools-2-24-0] and [2.25.0][devtools-2-25-0] releases of DevTools. [devtools-2-24-0]: https://docs.flutter.dev/tools/devtools/release-notes/release-notes-2.24.0 [devtools-2-25-0]: https://docs.flutter.dev/tools/devtools/release-notes/release-notes-2.25.0 ##### Linter - Added new static analysis lints you can [enable][enable-lints] in your package's `analysis_options.yaml` file: - [`no_self_assignments`](https://dart.dev/lints/no_self_assignments) - [`no_wildcard_variable_uses`](https://dart.dev/lints/no_wildcard_variable_uses) [enable-lints]: https://dart.dev/tools/analysis#enabling-linter-rules ### [`v3.0.7`](https://togithub.com/dart-lang/sdk/blob/HEAD/CHANGELOG.md#307---2023-07-26) [Compare Source](https://togithub.com/dart-lang/sdk/compare/3.0.6...3.0.7) This is a patch release that: - Fixes a bug in dart2js which would cause certain uses of records to lead to bad codegen causing a `TypeError` or `NoSuchMethodError` to be thrown at runtime (issue [#​53001]).

To use them, set your package's [SDK constraint][language version] lower bound to 3.0 or greater (`sdk: '^3.0.0'`). [language version]: https://dart.dev/guides/language/evolution - **[Records]**: Records are anonymous immutable data structures that let you aggregate multiple values together, similar to [tuples][] in other languages. With records, you can return multiple values from a function, create composite map keys, or use them any other place where you want to bundle a couple of objects together. For example, using a record to return two values: ```dart (double x, double y) geoLocation(String name) { if (name == 'Nairobi') { return (-1.2921, 36.8219); } else { ... } } ``` - **[Pattern matching]**: Expressions build values out of smaller pieces. Conversely, patterns are an expressive tool for decomposing values back into their constituent parts. Patterns can call getters on an object, access elements from a list, pull fields out of a record, etc. For example, we can destructure the record from the previous example like so: ```dart var (lat, long) = geoLocation('Nairobi'); print('Nairobi is at $lat, $long.'); ``` Patterns can also be used in [switch cases]. There, you can destructure values and also test them to see if they have a certain type or value: ```dart switch (object) { case [int a]: print('A list with a single integer element $a'); case ('name', _): print('A two-element record whose first field is "name".'); default: print('Some other object.'); } ``` Also, as you can see, non-empty switch cases no longer need `break;` statements. **Breaking change**: Dart 3.0 interprets [switch cases] as patterns instead of constant expressions. Most constant expressions found in switch cases are valid patterns with the same meaning (named constants, literals, etc.). You may need to tweak a few constant expressions to make them valid. This only affects libraries that have upgraded to language version 3.0. - **[Switch expressions]**: Switch expressions allow you to use patterns and multi-way branching in contexts where a statement isn't allowed: ```dart return TextButton( onPressed: _goPrevious, child: Text(switch (page) { 0 => 'Exit story', 1 => 'First page', _ when page == _lastPage => 'Start over', _ => 'Previous page', }), ); ``` - **[If-case statements and elements]**: A new if construct that matches a value against a pattern and executes the then or else branch depending on whether the pattern matches: ```dart if (json case ['user', var name]) { print('Got user message for user $name.'); } ``` There is also a corresponding [if-case element] that can be used in collection literals. - **[Sealed classes]**: When you mark a type `sealed`, the compiler ensures that switches on values of that type [exhaustively cover] every subtype. This enables you to program in an [algebraic datatype][] style with the compile-time safety you expect: ```dart sealed class Amigo {} class Lucky extends Amigo {} class Dusty extends Amigo {} class Ned extends Amigo {} String lastName(Amigo amigo) => switch (amigo) { Lucky _ => 'Day', Ned _ => 'Nederlander', }; ``` In this last example, the compiler reports an error that the switch doesn't cover the subclass `Dusty`. - **[Class modifiers]**: New modifiers `final`, `interface`, `base`, and `mixin` on `class` and `mixin` declarations let you control how the type can be used. By default, Dart is flexible in that a single class declaration can be used as an interface, a superclass, or even a mixin. This flexibility can make it harder to evolve an API over time without breaking users. We mostly keep the current flexible defaults, but these new modifiers give you finer-grained control over how the type can be used. **Breaking change:** Class declarations from libraries that have been upgraded to Dart 3.0 can no longer be used as mixins by default. If you want the class to be usable as both a class and a mixin, mark it [`mixin class`][mixin class]. If you want it to be used only as a mixin, make it a `mixin` declaration. If you haven't upgraded a class to Dart 3.0, you can still use it as a mixin. - **Breaking change** [#​50902][]: Dart reports a compile-time error if a `continue` statement targets a [label] that is not a loop (`for`, `do` and `while` statements) or a `switch` member. Fix this by changing the `continue` to target a valid labeled statement. - **Breaking change** [language/#​2357][]: Starting in language version 3.0, Dart reports a compile-time error if a colon (`:`) is used as the separator before the default value of an optional named parameter. Fix this by changing the colon (`:`) to an equal sign (`=`).

The following existing classes have been made mixin classes: - `Iterable` - `IterableMixin` (now alias for `Iterable`) - `IterableBase` (now alias for `Iterable`) - `ListMixin` - `SetMixin` - `MapMixin` - `LinkedListEntry` - `StringConversionSink` ##### `dart:core` - Added `bool.parse` and `bool.tryParse` static methods. - Added `DateTime.timestamp()` constructor to get current time as UTC. - The type of `RegExpMatch.pattern` is now `RegExp`, not just `Pattern`. - **Breaking change** [#​49529][]: - Removed the deprecated `List` constructor, as it wasn't null safe. Use list literals (e.g. `[]` for an empty list or `[]` for an empty typed list) or [`List.filled`][List.filled]. - Removed the deprecated `onError` argument on [`int.parse`][int.parse], [`double.parse`][double.parse], and [`num.parse`][num.parse]. Use the [`tryParse`][tryParse] method instead. - Removed the deprecated [`proxy`][proxy] and [`Provisional`][Provisional] annotations. The original `proxy` annotation has no effect in Dart 2, and the `Provisional` type and [`provisional`][provisional] constant were only used internally during the Dart 2.0 development process. - Removed the deprecated [`Deprecated.expires`][Deprecated.expires] getter. Use [`Deprecated.message`][Deprecated.message] instead. - Removed the deprecated [`CastError`][CastError] error. Use [`TypeError`][TypeError] instead. - Removed the deprecated [`FallThroughError`][FallThroughError] error. The kind of fall-through previously throwing this error was made a compile-time error in Dart 2.0. - Removed the deprecated [`NullThrownError`][NullThrownError] error. This error is never thrown from null safe code. - Removed the deprecated [`AbstractClassInstantiationError`][AbstractClassInstantiationError] error. It was made a compile-time error to call the constructor of an abstract class in Dart 2.0. - Removed the deprecated [`CyclicInitializationError`][CyclicInitializationError]. Cyclic dependencies are no longer detected at runtime in null safe code. Such code will fail in other ways instead, possibly with a StackOverflowError. - Removed the deprecated [`NoSuchMethodError`][NoSuchMethodError] default constructor. Use the [`NoSuchMethodError.withInvocation`][NoSuchMethodError.withInvocation] named constructor instead. - Removed the deprecated [`BidirectionalIterator`][BidirectionalIterator] class. Existing bidirectional iterators can still work, they just don't have a shared supertype locking them to a specific name for moving backwards. - **Breaking change when migrating code to Dart 3.0**: Some changes to platform libraries only affect code when that code is migrated to language version 3.0. - The `Function` type can no longer be implemented, extended or mixed in. Since Dart 2.0 writing `implements Function` has been allowed for backwards compatibility, but it has not had any effect. In Dart 3.0, the `Function` type is `final` and cannot be subtyped, preventing code from mistakenly assuming it works. - The following declarations can only be implemented, not extended: - `Comparable` - `Exception` - `Iterator` - `Pattern` - `Match` - `RegExp` - `RegExpMatch` - `StackTrace` - `StringSink` None of these declarations contained any implementation to inherit, and are marked as `interface` to signify that they are only intended as interfaces. - The following declarations can no longer be implemented or extended: - `MapEntry` - `OutOfMemoryError` - `StackOverflowError` - `Expando` - `WeakReference` - `Finalizer` The `MapEntry` value class is restricted to enable later optimizations. The remaining classes are tightly coupled to the platform and not intended to be subclassed or implemented.

Also exported from `dart:core`. - Deprecated the `HasNextIterator` class ([#​50883][]). - **Breaking change when migrating code to Dart 3.0**: Some changes to platform libraries only affect code when it is migrated to language version 3.0. - The following interface can no longer be extended, only implemented: - `Queue` - The following implementation classes can no longer be implemented: - `LinkedList` - `LinkedListEntry` - The following implementation classes can no longer be implemented or extended: - `HasNextIterator` (Also deprecated.) - `HashMap` - `LinkedHashMap` - `HashSet` - `LinkedHashSet` - `DoubleLinkedQueue` - `ListQueue` - `SplayTreeMap` - `SplayTreeSet` [#​50883]: https://togithub.com/dart-lang/sdk/issues/50883 ##### `dart:developer` - **Breaking change** [#​49529][]: - Removed the deprecated [`MAX_USER_TAGS`][MAX_USER_TAGS] constant. Use [`maxUserTags`][maxUserTags] instead. - Callbacks passed to `registerExtension` will be run in the zone from which they are registered. - **Breaking change** [#​50231][]: - Removed the deprecated [`Metrics`][Metrics], [`Metric`][Metric], [`Counter`][Counter], and [`Gauge`][Gauge] classes as they have been broken since Dart 2.0.

See [#​49536](https://togithub.com/dart-lang/sdk/issues/49536) for details. ##### `dart:math` - **Breaking change when migrating code to Dart 3.0**: Some changes to platform libraries only affect code when it is migrated to language version 3.0. - The `Random` interface can only be implemented, not extended. ##### `dart:io` - Added `name` and `signalNumber` to the `ProcessSignal` class. - Deprecate `NetworkInterface.listSupported`. Has always returned true since Dart 2.3. - Finalize `httpEnableTimelineLogging` parameter name transition from `enable` to `enabled`. See [#​43638][]. - Favor IPv4 connections over IPv6 when connecting sockets. See [#​50868]. - **Breaking change** [#​51035][]: - Update `NetworkProfiling` to accommodate new `String` ids that are introduced in vm_service:11.0.0 [#​43638]: https://togithub.com/dart-lang/sdk/issues/43638 [#​50868]: https://togithub.com/dart-lang/sdk/issues/50868 [#​51035]: https://togithub.com/dart-lang/sdk/issues/51035 ##### `dart:js_util` - Added several helper functions to access more JavaScript operators, like `delete` and the `typeof` functionality. - `jsify` is now permissive and has inverse semantics to `dartify`. - `jsify` and `dartify` both handle types they understand natively more efficiently. - Signature of `callMethod` has been aligned with the other methods and now takes `Object` instead of `String`. ##### Tools ##### Observatory - Observatory is no longer served by default and users should instead use Dart DevTools. Users requiring specific functionality in Observatory should set the `--serve-observatory` flag. ##### Web Dev Compiler (DDC) - Removed deprecated command line flags `-k`, `--kernel`, and `--dart-sdk`. - The compile time flag `--nativeNonNullAsserts`, which ensures web library APIs are sound in their nullability, is by default set to true in sound mode. For more information on the flag, see [NATIVE_NULL_ASSERTIONS.md][]. [NATIVE_NULL_ASSERTIONS.md]: https://togithub.com/dart-lang/sdk/blob/main/sdk/lib/html/doc/NATIVE_NULL_ASSERTIONS.md ##### dart2js - The compile time flag `--native-null-assertions`, which ensures web library APIs are sound in their nullability, is by default set to true in sound mode, unless `-O3` or higher is passed, in which case they are not checked. For more information on the flag, see [NATIVE_NULL_ASSERTIONS.md][]. [NATIVE_NULL_ASSERTIONS.md]: https://togithub.com/dart-lang/sdk/blob/main/sdk/lib/html/doc/NATIVE_NULL_ASSERTIONS.md ##### Dart2js - Cleanup related to [#​46100](https://togithub.com/dart-lang/sdk/issues/46100): the internal dart2js snapshot fails unless it is called from a supported interface, such as `dart compile js`, `flutter build`, or `build_web_compilers`. This is not expected to be a visible change. ##### Formatter - Format `sync*` and `async*` functions with `=>` bodies. - Don't split after `<` in collection literals. - Better indentation of multiline function types inside type argument lists. - Fix bug where parameter metadata wouldn't always split when it should. ##### Analyzer - Most static analysis "hints" are converted to be "warnings," and any remaining hints are intended to be converted soon after the Dart 3.0 release. This means that any (previously) hints reported by `dart analyze` are now considered "fatal" (will result in a non-zero exit code). The previous behavior, where such hints (now warnings) are not fatal, can be achieved by using the `--no-fatal-warnings` flag. This behavior can also be altered, on a code-by-code basis, by [changing the severity of rules] in an analysis options file. - Add static enforcement of the SDK-only `@Since` annotation. When code in a package uses a Dart SDK element annotated with `@Since`, analyzer will report a warning if the package's [Dart SDK constraint] allows versions of Dart which don't include that element. - Protects the Dart Analysis Server against extreme memory usage by limiting the number of plugins per analysis context to 1. (issue \[[#​50981](https://togithub.com/dart-lang/sdk/issues/50981)]\[]). [changing the severity of rules]: https://dart.dev/tools/analysis#changing-the-severity-of-rules [Dart SDK constraint]: https://dart.dev/tools/pub/pubspec#sdk-constraints ##### Linter Updates the Linter to `1.35.0`, which includes changes that - add new lints: - `implicit_reopen` - `unnecessary_breaks` - `type_literal_in_constant_pattern` - `invalid_case_patterns` - update existing lints to support patterns and class modifiers - remove support for: - `enable_null_safety` - `invariant_booleans` - `prefer_bool_in_asserts` - `prefer_equal_for_default_values` - `super_goes_last` - fix `unnecessary_parenthesis` false-positives with null-aware expressions. - fix `void_checks` to allow assignments of `Future?` to parameters typed `FutureOr?`. - fix `use_build_context_synchronously` in if conditions. - fix a false positive for `avoid_private_typedef_functions` with generalized type aliases. - update `unnecessary_parenthesis` to detect some doubled parens. - update `void_checks` to allow returning `Never` as void. - update `no_adjacent_strings_in_list` to support set literals and for- and if-elements. - update `avoid_types_as_parameter_names` to handle type variables. - update `avoid_positional_boolean_parameters` to handle typedefs. - update `avoid_redundant_argument_values` to check parameters of redirecting constructors. - improve performance for `prefer_const_literals_to_create_immutables`. - update `use_build_context_synchronously` to check context properties. - improve `unnecessary_parenthesis` support for property accesses and method invocations. - update `unnecessary_parenthesis` to allow parentheses in more null-aware cascade contexts. - update `unreachable_from_main` to track static elements. - update `unnecessary_null_checks` to not report on arguments passed to `Future.value` or `Completer.complete`. - mark `always_use_package_imports` and `prefer_relative_imports` as incompatible rules. - update `only_throw_errors` to not report on `Never`-typed expressions. - update `unnecessary_lambdas` to not report with `late final` variables. - update `avoid_function_literals_in_foreach_calls` to not report with nullable- typed targets. - add new lint: `deprecated_member_use_from_same_package` which replaces the soft-deprecated analyzer hint of the same name. - update `public_member_api_docs` to not require docs on enum constructors. - update `prefer_void_to_null` to not report on as-expressions. ##### Migration tool removal The null safety migration tool (`dart migrate`) has been removed. If you still have code which needs to be migrated to null safety, please run `dart migrate` using Dart version 2.19, before upgrading to Dart version 3.0. ##### Pub - To preserve compatibility with null-safe code pre Dart 3, Pub will interpret a language constraint indicating a language version of `2.12` or higher and an upper bound of `<3.0.0` as `<4.0.0`. For example `>=2.19.2 <3.0.0` will be interpreted as `>=2.19.2 <4.0.0`. - `dart pub publish` will no longer warn about `dependency_overrides`. Dependency overrides only take effect in the root package of a resolution. - `dart pub token add` now verifies that the given token is valid for including in a header according to [RFC 6750 section 2.1](https://www.rfc-editor.org/rfc/rfc6750#section-2.1). This means they must contain only the characters: `^[a-zA-Z0-9._~+/=-]+$`. Before a failure would happen when attempting to send the authorization header. - `dart pub get` and related commands will now by default also update the dependencies in the `example` folder (if it exists). Use `--no-example` to avoid this. - On Windows the `PUB_CACHE` has moved to `%LOCALAPPDATA%`, since Dart 2.8 the `PUB_CACHE` has been created in `%LOCALAPPDATA%` when one wasn't present. Hence, this only affects users with a `PUB_CACHE` created by Dart 2.7 or earlier. If you have `path/to/.pub-cache/bin` in `PATH` you may need to update your `PATH`.
