Android Emulator可以上网但是App无法连接Firebase

Question

我正在尝试通过 AVD (Intellij) 在模拟器上调试 Flutter 应用程序。 在物理设备上一切正常。 我可以通过模拟器连接到inte.net（Chrome浏览器可以）但是我无法通过模拟器中的应用程序连接到Firebase服务器。

这是错误堆栈跟踪

我已将以下内容添加到 /android/app/main/AndroidManifest.xml

<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.INTERNET" />

我试过冷启动选项。 这不是 DNS 的问题，因为我可以通过模拟器中的 Chrome 连接到 Inte.net。 我目前使用的是 Android 10.0，但我也尝试过 11。可能缺少什么？

这看起来像是 Firebase 在 Android 模拟器上的一个未解决的问题。 所以我放弃了在模拟器上运行它，而是使用 Edge (Web) 来调试并继续开发

只需确保传递选项，否则您将无法在任何浏览器或 Windows 应用程序上运行您的应用程序。 这是 WEB 所需的配置。

Future main() async {
  WidgetsFlutterBinding.ensureInitialized();
  await Firebase.initializeApp(options: DefaultFirebaseOptions.currentPlatform);
  runApp(const MyApp());
}
