downgrade analysis failed failed with 5 errors:

• MISSING_REQUIRED_ARGUMENT - lib/src/old_extended_nested_scroll_view.dart:516:8 - The named parameter 'devicePixelRatio' is required, but there's no corresponding argument.
• INVALID_OVERRIDE - lib/src/old_extended_nested_scroll_view.dart:525:24 - '_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})').

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.
