在安装 firebase_auth 插件并更新其他 firebase 插件版本后，我遇到了一些错误。我尝试了一些解决方案，包括降级 firebase auth 插件版本并向我的 gradle 文件添加一些行，但它仍然无法正常工作。

pubspec.yaml:

 dependencies:
  flutter:
    sdk: flutter
  shared_preferences: ^0.4.3
  json_annotation: ^1.2.0
  geolocator: ^2.1.0

            // Signing with the debug keys for now, so `flutter run --release` works.
            signingConfig signingConfigs.debug
        }
    }

最佳答案

我最终通过以下操作修复了我的错误:https://github.com/flutter/flutter/issues/27128#issuecomment-457918930

这里有一些其他注意事项:

1. 更新 gradle-wrapper.properties 中的 distributionUrl 时，我使用了 4.10.2。我猜您的版本可能会有所不同，具体取决于您何时执行此操作。
2. 如果找不到“将项目与 Gradle 文件同步”命令，请执行此 Not able to sync dependency in build.gradle in flutter
