Flutter [firebase_messaging] IOS 构建错误

Question

我对 Firebase 消息（ https://pub.dev/packages/firebase_messaging ）有疑问。 将此添加到项目后，我无法在 IOS 中构建。

我试过了：

flutter clean
flutter precache    
pod deintegrate
pod setup
pod install

尝试：删除 Podfile.lock

编辑/删除 WorkspaceSettings.xcsettings

将构建系统更改为旧版

我在实际项目中遇到了同样的问题。 我创建了空白项目，构建 ios 并在模拟器上运行。 在我添加 FirebaseMessaging 后得到这个构建错误。 尝试了我发短信的方法，但对我不起作用。 错误：
