Support for flutter 3.47.0

[rjahn]

Could you support (migrate) material_ui to avoid:

error: The argument type 'ColorScheme (where ColorScheme is defined in ../.pub-cache/hosted/pub.dev/material_ui-1.1.0/lib/src/color_scheme.dart)' can't be assigned to the parameter type 'ColorScheme (where ColorScheme is defined in /../flutter/packages/flutter/lib/src/material/color_scheme.dart)'.

e.g.

dart fix --apply --code=migrate_design_widgets
