我正在使用 firebase 开发 flutter 应用程序，当我使用 firebaseAuth 插件应用程序时出现以下错误

我正在使用这些库-

firebase_auth: ^0.15.5+2
firebase_storage: ^3.1.1
cloud_firestore: ^0.13.4

有人知道如何解决这个错误吗？，我已经做了以下事情

flutter clean
deleted podfile.lock
deleted pods folder
pod deintegrate
pod repo update
pod install

但不要帮我解决这个错误

我们遇到了同样的错误。看来这是一个 firebase_auth 依赖项错误(firebase_core v0.4.4+2)。

首先，运行 flutter clean，然后将 pubspec.yaml 的依赖项更改为

dependencies: 
  firebase_auth: 0.15.4
dependency_overrides:
  firebase_core: 0.4.4

希望对你有帮助!
