digit-separators language feature not enabled ?

[PiotrFLEURY]

Using digit-separators Dart language feature raise an error:

Could not format because the source could not be parsed:
line 23, column 17 of test/step_definitions.dart: This requires the 'digit-separators' language feature to be enabled.
   ╷
23 │         amount: 2_000,
   │                 ^^^^^
   ╵

This language feature has been enabled since Dart 3.6 as specified in the official documentation here

I ran a flutter-version in the CI and everything seems to be well configured. Right Flutter and Dart SDK versions.

Run flutter --version
  flutter --version

Everything's works fine on my local machine using Flutter 3.27.1 and Dart 3.6.

Did I miss something in the configuration ? Sounds strange to have two distinct behaviors using the same SDK version on both environments.

Edit:

This is linked to an issue with the dart format command in the 3.6 version

I openned an issue dart-lang/sdk#59815

This is not caused by flutter-action => closing
