Hi When i try to flutter run command i get error message below :

Using hardware rendering with device sdk gphone x86. If you notice graphics artifacts, consider enabling software rendering with "--enable-software-rendering". Launching lib\main.dart on sdk gphone x86 in debug mode... Error: Cannot run with sound null safety, because the following dependencies don't support null safety:

  • package:flutter_bloc
  • package:dart_json_mapper
  • package:bloc
  • package:provider
  • package:formz

For solutions, see https://dart.dev/go/unsound-null-safety

i fixed by added this line // @ dart = 2.9 on top of the main.dart file.

Hello,

No need to downgrade the dart version, if you use intelliJ can use the generated configuration (dev and prod). If you want to use the command line you can add flutter run --no-sound-null-safety
