After running the Flutter project, I get this error. What can I do to solve it?
Error: The method 'setMockMessageHandler' isn't defined for the class 'BasicMessageChannel<dynamic>'.
I have tried:
flutter pub upgrage
and this is the result:
No dependencies changed.
1 package is discontinued.
76 packages have newer versions incompatible with dependency constraints.
Try `flutter pub outdated` for more information.
also:
flutter clean
flutter pub upgrade --major-versions
did not help

flutter pub cache repair
