:-1: Multiple commands produce 'Flutter.framework':

1) Target 'Runner' has copy command from '/Users/yuanzhiying/cocos-embed-flutter/frameworks/runtime-src/flutter_module/.ios/Flutter/engine/Flutter.framework' to '/Users/yuanzhiying/Library/Developer/Xcode/DerivedData/Runner-eptbkhpzfgbvcachmhewftmvxjdp/Build/Products/Debug-iphonesimulator/Runner.app/Frameworks/Flutter.framework'

2) That command depends on command in Target 'Runner': script phase “[CP] Embed Pods Frameworks”
