I am trying to build my flutter project in android studio, Note that I did not use fade Duration in this project

and I have this problem when I upgrade flutter and android studio

The issue :


/C:/Users/USER/AppData/Local/Pub/Cache/hosted/pub.dartlang.org/flutter_math_fork-0.5.0/lib/src/widgets/selection/overlay.dart:195:24: Warning: Operand of null-aware operation '!' has type 'SchedulerBinding' which excludes null.
 - 'SchedulerBinding' is from 'package:flutter/src/scheduler/binding.dart' ('/D:/src1/flutter/packages/flutter/lib/src/scheduler/binding.dart').
      SchedulerBinding.instance!.addPostFrameCallback(_markNeedsBuild);
                       ^

        duration: TextSelectionOverlay.fadeDuration, vsync: this);
                                       ^^^^^^^^^^^^

The lib flutter_math_fork-0.5.0 may be used on the another library, but the flutter latest not support the method TextSelectionOverlay.fadeDuration You just override the newer version of flutter_math_fork on pubspec.yaml

Example:

dependency_overrides:
  flutter_math_fork: ^0.6.1
