downgrade analysis failed failed with 3 errors:

• RETURN_OF_INVALID_TYPE - lib/extensions/build_context/build_context_theme.dart:232:34 - A value of type 'AppBarThemeData' can't be returned from the function 'appBarTheme' because it has a return type of 'AppBarTheme'.
• RETURN_OF_INVALID_TYPE - lib/extensions/build_context/build_context_theme.dart:306:46 - A value of type 'BottomAppBarThemeData' can't be returned from the function 'bottomAppBarTheme' because it has a return type of 'BottomAppBarTheme'.

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.
