Answer 1

I solved this issue yesterday;

Please check out your apple dev account on your xcode first, and run your project using xcode, and input your password, trust your certificate. After your xcode build success, you can run it on your idea ?Android Studio? now.

Answer 2

I have same issue and resolved by accident. Give it a try (not sure if this works)

flutter clean 
rm ios/Podfile ios/Podfile.lock pubspec.lock
rm -rf ios/Pods ios/Runner.xcworkspace
