    ** BUILD FAILED **

What have I done

  • flutter clean
  • removing DerivedData folder
  • xcode command tool select

flutter doctor comes without any problem. However, running this flutter project on XCode works fine.

I am just curious where the error is coming from? Since, I can't run the app by 'flutter run', I can't do any quick refresh.

I have come across the same problem. It was not xcode or Android studio's problem but Pubspec.yaml's. Try checking for any misspellings or typos in your pubspec.yaml. Even though there was a typo on pubspec.yaml, when i did pub get, it was fine, but when I rebuilt, it was crushed. It did not show the problem on pubspec.yaml while I was running on the IOS simulator, but when i checked the project on Chrome, it showed the problem. enter image description here

try the following commands

cd ios/
      pod cache clean --all
      pod deintegrate --verbose
      pod setup --verbose
      pod install --verbose
