Android Emulator可以上网但是App无法连接Firebase

Question

I'm trying to debug a Flutter app on an Emulator through AVD (Intellij). Everything works fine on a physical device. I can connect to the inte.net through the Emulator (Chrome browsing works) But I'm unable to connect to the Firebase server through the App in the emulator.

Here's the error stack trace

I have added the following to /android/app/main/AndroidManifest.xml

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

I have tried the cold boot option. It's not an issue with DNS because I CAN connect to the Inte.net through Chrome in the Emulator. I'm currently on Android 10.0 but I also tried 11. What could be missing?

This looks like an open unresolved issue with Firebase on Android emulators. So I gave up on running this on an emulator and instead using Edge (Web) instead to debug and continue with the development

Just make sure to pass in the options or else you WON'T be able to run your app on any browser or on Windows App. Here's the config needed for WEB.

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