[Firebase_Auth]: MicrosoftCredentials not working in signInWithCredential

[alfie-trbc]

Is there an existing issue for this?

• I have searched the existing issues.

Which plugins are affected?

Auth

Which platforms are affected?

Android, iOS

Description

Based on the Code Documentation which I initially checked, 3rd party login is feasible in microsoft and just get the accessToken and pass that to signInWithCredential:

This is the code documentation under [MicrosoftAuthProvider] class :

BUT in firebase documentation it says that this is not supported:

The error I'm encountering is:
([firebase_auth/channel-error] "dev.flutter.pigeon.firebase_auth_platform_interface.FirebaseAuthHostApi.signInWithCredential".)

Is microsoft really not supported via signInWithCredential? if that so, why the documentation under MicrosoftAuthProvider contradict the official firebase documentation?

Reproducing the issue

1.) I used flutter_web_auth_2 package for 3rd party authorize

2.) I get the auth code to use for getting the accessToken and refreshToken from microsoft API

3.) After that I created a credential like this:

  final credential = MicrosoftAuthProvider.credential(accessToken);

4.) passed the credential in signInWithCredential

  final userCredential = await auth.signInWithCredential(credential);

5.) It will get an error under signInWithCredential:

([firebase_auth/channel-error] "dev.flutter.pigeon.firebase_auth_platform_interface.FirebaseAuthHostApi.signInWithCredential".)

Hi @alfie-trbc, thanks for the report. signInWithCredential is indeed not supported for Microsoft as stated here. The documentation has to be updated accordingly.
