Appwrite Version above 8.2.0 will never allow the flutter App to build, received this error ":app:checkDebugDuplicateClasses"

[Whitehat645]

👟 Reproduction steps

This is the first time am trying to migrate from non worthy firebase, kindly tell me if was wrong.

steps to reproduce:

1. I have added the appwrite: 8.2.2 version in pubspec, then do a pub get. below is my pubspec file

   name: jarvisiot description: A new Flutter project.

   The following line prevents the package from being accidentally published to

   pub.dev using flutter pub publish. This is preferred for private packages.

   publish_to: 'none' # Remove this line if you wish to publish to pub.dev

The following defines the version and build number for your application.

A version number is three numbers separated by dots, like 1.2.43

followed by an optional build number separated by a +.

Both the version and the builder number may be overridden in flutter

build by specifying --build-name and --build-number, respectively.

In Android, build-name is used as versionName while build-number used as versionCode.

Read more about Android versioning at https://developer.android.com/studio/publish/versioning

In iOS, build-name is used as CFBundleShortVersionString while build-number is used as CFBundleVersion.

Read more about iOS versioning at

https://developer.apple.com/library/archive/documentation/General/Reference/InfoPlistKeyReference/Articles/CoreFoundationKeys.html

In Windows, build-name is used as the major, minor, and patch parts

of the product and file versions while build-number is used as the build suffix.

version: 1.0.0+1

environment: sdk: '>=2.19.0 <3.0.0'

Dependencies specify other packages that your package needs in order to work.

To automatically upgrade your package dependencies to the latest versions

consider running flutter pub upgrade --major-versions. Alternatively,

dependencies can be manually updated by changing the version numbers below to

the latest version available on pub.dev. To see which dependencies have newer

versions available, run flutter pub outdated.

dependencies: flutter: sdk: flutter

The following adds the Cupertino Icons font to your application.

Use with the CupertinoIcons class for iOS style icons.

cupertino_icons: ^1.0.2

appwrite: 8.2.0

dev_dependencies: flutter_test: sdk: flutter

The "flutter_lints" package below contains a set of recommended lints to

encourage good coding practices. The lint set provided by the package is

activated in the analysis_options.yaml file located at the root of your

package. See that file for information about deactivating specific lint

rules and activating additional ones.

flutter_lints: ^2.0.0

For information on the generic Dart part of this file, see the

following page: https://dart.dev/tools/pub/pubspec

The following section is specific to Flutter packages.

flutter:

The following line ensures that the Material Icons font is

included with your application, so that you can use the icons in

the material Icons class.

uses-material-design: true

To add assets to your application, add an assets section, like this:

assets:

- images/a_dot_burr.jpeg

- images/a_dot_ham.jpeg

An image asset can refer to one or more resolution-specific "variants", see

https://flutter.dev/assets-and-images/#resolution-aware

For details regarding adding assets from package dependencies, see

https://flutter.dev/assets-and-images/#from-packages

To add custom fonts to your application, add a fonts section here,

in this "flutter" section. Each entry in this list should have a

"family" key with the font family name, and a "fonts" key with a

list giving the asset and other descriptors for the font. For

example:

fonts:

- family: Schyler

fonts:

- asset: fonts/Schyler-Regular.ttf

- asset: fonts/Schyler-Italic.ttf

style: italic

- family: Trajan Pro

fonts:

- asset: fonts/TrajanPro.ttf

- asset: fonts/TrajanPro_Bold.ttf

weight: 700

#

For details regarding fonts from package dependencies,

see https://flutter.dev/custom-fonts/#from-packages

@Whitehat645 can you please update the issue description and remove unnecessary information, it's not readable to figure out the error you are getting.

[lohanidamodar]

@Whitehat645 I figured out the issue, this is because one of our dependencies, flutter_web_auth_2 uses newest version of kotlin version (1.8.0) the quickest solution for now is to update android/build.gradle

buildscript {
    ext.kotlin_version = '1.8.0'
    ...
}

[ThexXTURBOXx]

I am terribly sorry for this. I have pushed a new release for flutter_web_auth_2 which should fix the underlying issue.

[lohanidamodar]

@Whitehat645 can you confirm this issue is resolved?

[lohanidamodar]

This issue should be resolved with new releases. If you still have similar issue feel free to re-open the issue.
