当我尝试通过外部终端运行时，它工作正常

我已经尝试运行导出 UTF-8 命令，但没有任何反应。

我该如何解决这个问题？\n希望您能解答我的问题。\n谢谢您

Answer 1

删除Podfile, Podfile.lock, Pods folder, Runner.xcworkspace, Flutter.framwork(ios/Flutter 文件夹中)

flutter clean

flutter build ios

或者试试这个

rm ios/Podfile
flutter pub upgrade
flutter pub run
cd ios
pod init
pod update
flutter clean && flutter run
