[Flutter] ... duplicate symbols for architecture ... 에러

This can happen when project is inside an iCloud directory, causing file duplication. There are two workarounds I see:

1- Remove duplicate files from root project. Always run find command without -delete first to make sure you're not deleting unwanted files

find . -name \*\ 2.\*
find . -name \*\ 2.\* -delete
find . -name \*\ 3.\*
find . -name \*\ 3.\* -delete
flutter clean
flutter run

2- Clean/reinstall pods, with the commands below (on flutter project root)

cd ios
pod deintegrate
cd ..
flutter clean
flutter run
