• Running flutter pub outdated failed with the following output:

Note: material_color_utilities is pinned to version 0.11.1 by flutter from the flutter SDK.
See https://dart.dev/go/sdk-version-pinning for details.

0/10 points: All of the package dependencies are supported in the latest version

• Could not run flutter pub outdated: flutter pub get failed:

OUT:
Resolving dependencies...
ERR:
Note: material_color_utilities is pinned to version 0.11.1 by flutter from the flutter SDK.
See https://dart.dev/go/sdk-version-pinning for details.


Because flutter_turnstile depends on flutter from sdk which depends on material_color_utilities 0.11.1, material_color_utilities 0.11.1 is required.
So, because flutter_turnstile depends on material_color_utilities ^0.8.0, version solving failed.


You can try the following suggestion to make the pubspec resolve:
* Try upgrading your constraint on material_color_utilities: flutter pub add material_color_utilities:^0.11.1

Run flutter pub downgrade and then flutter analyze to reproduce the above problem.

You may run dart pub upgrade --tighten to update your dependency constraints, see dart.dev/go/downgrade-testing for details.
