Launching lib/main.dart on iPhone 12 Pro Max in `debug mode`

I just ran into this and fixed it as follows:

  • run command flutter upgrade
  • run command flutter clean
  • run command flutter pub get if you have missing dependencies
  • attach phone
  • run command flutter run

If it still fails, open the Xcode runner project, set your development team and run it directly from there.

After it runs, close Xcode, do a clean build, and run it using your preferred approach.
