我尝试过flutter clean，flutter build iOS但rm iOS/Podfile根本没用。我该如何解决这个问题？这是我的flutter doctor和flutter --version下面的。

Answer 1

从终端运行：

flutter clean

flutter pub get

pod install// cd 进入ios文件夹

Answer 2

哦，我意识到发生这种情况是因为我通过 Xcode 更改了我的应用程序名称，所以我将以前的 pod 文件放回文件夹并按照https://github.com/flutter/flutter/issues/25370#issuecomment-540947710iOS的方式进行操作 ，然后，它就像魅力一样！希望对您有帮助。
