xcode - 找不到“FLTFirebasePlugin”颤振的协议声明

Question

我最近遇到了这个让我做噩梦好几天的错误，基本上当我尝试使用 FirebaseAuth 和 FirebaseCore 时，XCode 一直在向我抛出这个奇怪的错误，如图所示，这是 Flutter 构建日志：

   Launching lib/main.dart on iPhone 12 Pro in debug mode...

Could not build the application for the simulator.
Error launching application on iPhone 12 Pro.

这些是我在 .yaml 中导入的 Firebase 库

firebase_core: ^1.4.0
  firebase_analytics: ^8.2.0
  firebase_auth: ^3.0.1
  cloud_firestore: ^2.4.0
  firebase_storage: ^10.0.1

我的 Xcode 版本是 12.2

如果有人可以帮助我，我会非常感激，谢谢。
