If you are looking for help, please confirm the following...

• I confirm I have searched the Docs, Codemagic Sample Projects, and GitHub Discussions.

Hi @zelle7, you as well, try to lower the flutter version from channel Stable to 3.22.3

[zelle7]

@dtrdic thx I did

flutter pub cache clean
flutter channel stable
flutter pub get

This seemed to help. Thx!

[dtrdic]

Hi @MilanRibadiya please try lowering the flutter version from flutter channel Stable to 3.22.3. It seems that this error is occurring in the stable version that was released a few days ago by Flutter. Check also this ongoing discussion for reference

[MilanRibadiya]

@dtrdic It's working for me. Thanks for correct answer.

[al-batol]

flutter pub cache clean
flutter pub upgrade win32
flutter channel stable
flutter pub get
flutter pub outdated
flutter pub upgrade --major-versions
flutter run
