Encountered error while building for device.

example of the things i tried:

pod deintegrate
rm podfile.lock
rm pubspec.lock
flutter clean
flutter run

and just about anything similar you could immagine i also tried removing the file from the path indicated and removing the dependency from pubspec.yaml but it didn’t work

flutter doctor output :

I found a solution in another question on Stack!

Backup ios/Runner folder.
Delete the ios folder.
Run flutter create (your project name). in the previous folder where you have your project(cd users/user/"projects_folder") (this will recreate your ios folder).
Paste your Runner backup in the ios folder (into the project).
Open Runner.xcworkspace (into ios folder) and there, check the Version, the Bundle ID, all the info.
(If do you Have Firebase, you have to copy and paste again the Google Service-Info.Plist into the Runner folder (Always through Xcode) (If do you do this manually, it doesn't work).

Finally, flutter run and should work!

If flutter run fails:

cd ios
pod install
cd ..
flutter run

can't build IOS
