We need to bump material_color_utilities, and it is an SDK dependency.

new colors doesn't seem to be added in Scheme and they apparently moved to DynamicScheme as Scheme is deprecated (see this)

this package seem to direct take CorePalette from android. I tried to make following changes locally according to their migration guide

// corepalette_to_colorscheme.dart
final SchemeTonalSpot scheme;
    
    switch (brightness) {
      case Brightness.light:
        scheme = SchemeTonalSpot(
            sourceColorHct: Hct.fromInt(primary.keyColor.toInt()),
            isDark: false,
            contrastLevel: 0.0);
        break;
      case Brightness.dark:
        scheme = SchemeTonalSpot(
            sourceColorHct: Hct.fromInt(primary.keyColor.toInt()),
            isDark: true,
            contrastLevel: 0.0);
        break;
    }
...
return ColorScheme(
      primary: Color(MaterialDynamicColors.primary.getArgb(scheme)),
      onPrimary: Color(MaterialDynamicColors.onPrimary.getArgb(scheme)),
...

but the unit test fails

dynamic_color: Core palette detected.

Shouldn't just correcting expecting colors in test file enough if everything else works perfectly? (not based on this error but checking what's the real output of given colorscheme in test on md3 colorscheme generator, as colorscheme colors changed, now we need to change test file too)

@andr202
you have a valid point
but theoretical the test doesn't needs to be changed. in the test file a container is given primary color and tested with the expected color which passes. in this case, the primary color gets way off from expected color for some reason. I'm still looking into it (and now I'm clueless)
