what should I do to resolve warning from third party in flutter-CodePudding

Today when I start debbuging the flutter(v3.0.4) project, shows warning like this:

 - 'WidgetsBinding' is from 'package:flutter/src/widgets/binding.dart' ('../../../../fvm/versions/3.0.4/packages/flutter/lib/src/widgets/binding.dart').
        WidgetsBinding.instance?.scheduleFrameCallback((_) => animateRemove());

 - 'SchedulerBinding' is from 'package:flutter/src/scheduler/binding.dart' ('../../../../fvm/versions/3.0.4/packages/flutter/lib/src/scheduler/binding.dart').
      SchedulerBinding.instance!.addPostFrameCallback((_) {

      SchedulerBinding.instance!.addPostFrameCallback((_) {

this warning was come from the third party dependencies, it it possible to resolve the warnings? I did not any warning in my flutter project. what should I do to make the warning disappeared?

CodePudding user response：

This is normal, since the Flutter 3 update, the instance property has been made non-nullable. Not all packages have been updated to accommodate this yet, which is why you're seeing all these warnings.

The only thing to do is check the packages for updates regularly, and if there are, updating your pubspec.yaml to use the latest version.
