After upgrading, my old Flutter project using Vcode cannot build anymore with tons of errors as below. I have tried:
- deleting Podfile.lock
- pod cache clean --all
- rm -rf ~/Library/Caches/CocoaPods
- rm -rf ~/Library/Developer/Xcode/DerivedData/*
- rm -rf Pods
- pod deintegrate
- pod setup
- pod install
flutter doctor -v
