downgrade analysis failed failed with 3 errors:

• MISSING_REQUIRED_ARGUMENT - lib/preload_page_view.dart:170:8 - The named parameter 'devicePixelRatio' is required, but there's no corresponding argument.
• INVALID_OVERRIDE - lib/preload_page_view.dart:179:15 - 'PageMetrics.copyWith' ('PageMetrics Function({AxisDirection? axisDirection, double? maxScrollExtent, double? minScrollExtent, double? pixels, double? viewportDimension, double? viewportFraction})') 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.
