当我尝试在 Android Studio 中运行 flutter 代码时，出现以下错误：

此问题是由于最近更新包firebase_auth（特别是版本 4.13.0，现在导出一个AuthProvider类）而引起的命名冲突。此更改在此拉取请求中引入，并在 2023 年 11 月 9 日的发行说明中提到。

Shahed Emon 在上面的评论中指出了可能的修复方法：

• 重命名你自己的AuthProvider类以避免冲突，或者......
• 从包中导入冲突的类时使用别名firebase_auth，如下所示：

import 'package:firebase_auth_platform_interface/src/auth_provider.dart' as firebase;

通过在导入firebase_auth包时使用别名，您可以防止AuthProvider该包中的 无意中合并到不引用firebase_auth's的现有代码中AuthProvider。

作为参考，这是我收到的错误：

无法构建 iOS 应用程序

无法为设备构建预编译应用程序。

错误（Xcode）：lib/feature/auth/provider/firebase_auth_provider.dart:3:1：错误：“AuthProvider”是从“package:app/feature/auth/provider/auth_provider.dart”和“package:firebase_auth_platform_interface”导入的/src/auth_provider.dart'。
