Support for Flutter 3.10 & Dart 3.0

[aldee]

Hi, since Flutter 3.10 is here, when I tried to use the plugin, it shows an error because the command executed by the plugin limits intl_utils activation only if its within version range ">=1.0.0 <2.0.0", which doesn't support null-safety, which is required by Dart 3.0

Here's the error message that shows up:

`flutter --no-color pub global activate intl_utils ">=1.0.0 <2.0.0" Package intl_utils is currently active at version 2.8.2. Resolving dependencies... The current Dart SDK version is 3.0.0.

Because pub global activate depends on intl_utils <2.0.0 which doesn't support null safety, version solving failed.

The lower bound of "sdk: '>=2.2.2 <3.0.0'" must be 2.12.0 or higher to enable null safety.`

Here's the output from flutter doctor --verbose:

Hi @aldee,

It seems that you have sdk set to>=2.2.2 <3.0.0 within your pubspec.yaml file. Is there any reason why it is not set to at least >=2.12.0 <3.0.0 as you are using the latest Flutter version?

The Flutter Intl plugin determines which version of the intl_utils package (package used for generating the localization code) to globally activate based on the sdk value (null-safety requires at least min value of the 2.12.0) within the pubspec.yaml file, or by using the same version of the intl_utils package that is listed as a dependency within the pubspec.yaml file.

So, updating the version of sdk to >=2.12.0 <3.0.0 or adding the intl_utils package as a dev dependency (e.g. intl_utils: ^2.8.2) should solve the issue.

Hope this info helps!

Hi, thanks for your response.

In my pubspec.yaml, I already set the sdk to >=3.0.0-0 <4.0.0

But I've added intl_utils package as dev_dependency, and it works now. Thank you!

Although I'm still curious about why it resolved to that sdk range when running intl_utils, when even in my pubspec.lock file it resolved to >=3.0.0-0 <4.0.0

Good catch!

It looks like the code for resolving which version of the intl_utils to activate needs to be updated to also include the latest Dart versions (>=3.0.0).

Let's leave this issue open until we fix it.

I see, alright then. Thanks again for your help!

Yes please!!!

This should be fixed now with the Flutter Intl 1.18.2.

Closing this issue as resolved. In case of irregularities, feel free to open it again.
