downgrade analysis failed failed with 2 errors:

• INVALID_OVERRIDE - lib/src/bindings/isolate_bindings/absent_scheduler_binding.dart:87:7 - '_AbsentSchedulerBinding.scheduleFrameCallback' ('int Function(void Function(Duration), {bool rescheduling})') isn't a valid override of 'SchedulerBinding.scheduleFrameCallback' ('int Function(void Function(Duration), {bool rescheduling, bool scheduleNewFrame})').
• INVALID_IMPLEMENTATION_OVERRIDE - lib/src/bindings/isolate_bindings/isolate_binding.dart:13:7 - '_AbsentSchedulerBinding.scheduleFrameCallback' ('int Function(void Function(Duration), {bool rescheduling})') isn't a valid concrete implementation of 'SchedulerBinding.scheduleFrameCallback' ('int Function(void Function(Duration), {bool rescheduling, bool scheduleNewFrame})').

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.
