Application depends on flutter from sdk which depends on material_color_utilities 0.2.0, material_color_utilities 0.2.0 is required. #110

I'm following one of the Flutter team's videos "Material 3 from design to deployment" linked from here: https://m3.material.io/develop/flutter

The example uses material_color_utilities to manage the application's theming techniques, and specifically, the example uses Scheme.toColorScheme() to generate a new ColorScheme based on the application's theme customization.

However, when I depend on material_color_utilities ^0.8.0 - which provides this functionality - I get the following error:

[app_client] flutter pub get
Resolving dependencies...
Because app_client depends on flutter from sdk which depends on material_color_utilities 0.2.0, material_color_utilities 0.2.0 is required.
So, because app_client depends on material_color_utilities 0.8.0, version solving failed.
exit code 1

Any thoughts on how to resolve this dependency issue and make use of the updated Material 3 functionality?

I'm developing production apps with the following development environment:

Thanks for posting this issue. I have the same problem and have not found a work-around without porting over and refactoring the source code. Not recommended.

Hopefully someone will provide a way to resolve this dependency.

You're welcome @TriMontana. I suspect that the answer will be to switch to one of the development channels - but that makes me somewhat nervous when publishing production apps. Hopefully we get an answer either way.

I have same problems and solved by upgrading the flutter using command flutter upgrade. I can use the material_color_utilities 0.5.0 after updating the flutter.

This is my latest flutter version.
