downgrade analysis failed failed with 12 errors:

• MISSING_REQUIRED_ARGUMENT - lib/sliver/contextual_scrollview.dart:379:8 - The named parameter 'devicePixelRatio' is required, but there's no corresponding argument.
• INVALID_OVERRIDE - lib/sliver/contextual_scrollview.dart:388:24 - '_NestedScrollMetrics.copyWith' ('_NestedScrollMetrics Function({AxisDirection? axisDirection, double? correctionOffset, double? maxRange, double? maxScrollExtent, double? minRange, double? minScrollExtent, double? pixels, double? viewportDimension})') isn't a valid override of 'ScrollMetrics.copyWith' ('ScrollMetrics Function({AxisDirection? axisDirection, double? devicePixelRatio, double? maxScrollExtent, double? minScrollExtent, double? pixels, double? viewportDimension})').
• INVALID_ASSIGNMENT - lib/widgets/contextual_app_bar.dart:204:37 - A value of type 'AppBarThemeData' can't be assigned to a variable of type 'AppBarTheme'.

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.
