Answer 1

Run flutter upgrade to upgrade to most recent version of Flutter. After that, flutter clean and build again. This should solve your problem.

Answer 2

Only thing which solved me this problem is to clear the pub cache by deleting pubspec.lock file and re running flutter run command.

This mainly happens due to the error in the cached plugin files

Answer 3

Run following command and resolve your issue

1. flutter clean
2. rm ios/Podfile ios/Podfile.lock pubspec.lock
3. rm -rf ios/Pods ios/Runner.xcworkspace
4. flutter run
