🐛 [firebase_auth] authDomain value is not used when calling auth.signInWithProvider

[sidlatau]

Bug report

When using OAuthProvider method auth.signInWithProvider(microsoftProvider); it is not possible to change redirect_uri parameter even when authDomain in firebase options is set. Default redirect uri https://[app].firebaseapp.com/__/auth/handler
is always used.

Steps to reproduce

  final app = await Firebase.initializeApp(
        options: FirebaseOptions(
            apiKey: '...',
            appId: '...',
            authDomain: 'app.client1.com',
            messagingSenderId: '..',
            projectId: '..',
            storageBucket: '....appspot.com',
          ),
      );

  print(app.options.authDomain); // Prints "null"

  final auth = FirebaseAuth.instanceFor( app: app);
  final microsoftProvider = MicrosoftAuthProvider();

   await auth.signInWithProvider(microsoftProvider); 

   // Expected redirect uri: https://app.client1.com/__/auth/handler
   // Actual: https://[app].firebaseapp.com/__/auth/handler

Expected behavior

When authDomain is provided in firebase options, it should be used in redirect uri when calling signInWithProvider

Thanks for the report. Using code sample provided, I see the same behaviour.

[Lyokone]

Hello :)
I've checked your issue, and AuthDomain is only supported on web. Can you confirm that it's working properly on web?
We can open a ticket in Android / iOS to get AuthDomain support in the main SDK if needed.

[sidlatau]

Yes, we are using AuthDomain property on web and it is working properly. In my opinion it should work the same in Android and iOS too.

[eli1stark]

@darshankawar @Lyokone Hi, is there any timeline for adding support for authDomain on Android and iOS, can we please open a ticket to get support if it's not opened yet?

[JonasTriki]

Any updates on this?

[CephasPeter]

Any updates on this? @darshankawar @Lyokone

[russellwheatley]

Support for custom auth domain has been released in the latest Firebase iOS SDK 10.16.0: https://firebase.google.com/support/release-notes/ios#authentication

We have an open PR for bumping Firebase iOS SDK to 10.16.0 here: #11698

Here is the open ticket for Firebase android SDK here that you may wish to thumb up to give it a higher priority: firebase/firebase-android-sdk#4805

[davidmigloz]

It seems it is now available in Android as well:

• Support for setting authDomain on Android firebase-android-sdk#4805 (comment)
• https://firebase.google.com/support/release-notes/android#auth_v22-2-0
