I know this issue pre exists before and people have managed to fix it by two methods. However both those two methods don't help me, and I think mine is a peculiar issue, please help, I am printing the logs below.

Also, the flutter run --verbose command was not entirely printed in console and looks too big to include here, so I cut short to the last red output only.

Steps to Reproduce

  1. Run flutter run.
  2. Update the files as follows: pubspec.yaml include firebase_auth_ui, cloud_firestore, google_sign_in, firebase_storage, image_picker
  3. Look at the console output

Expected results:
Executed the application on iPhone simulator and console output saying 'Installing and launching on iPhone simulator'

Actual results:
Launching lib/main.dart on iPhone 11 Pro Max in debug mode...

Running pod install... 20.9s
Running Xcode build...
