🐛 [firebase_auth] firebase_auth/account-exists-with-different-credential #7457

Bug report

I'm trying to allow my app users to sign in using their Facebook and Google accounts, Google sign-in works perfectly but Facebook is showing an error of having multiple accounts. it should allow my users to sign in multiple times with the same account and firebase id 

[ERROR:flutter/lib/ui/ui_dart_state.cc(209)] Unhandled Exception: [firebase_auth/account-exists-with-different-credential] An account already exists with the same email address but different sign-in credentials. Sign in using a provider associated with this email address.
E/flutter (24141): #0      MethodChannelFirebaseAuth.signInWithCredential (package:firebase_auth_platform_interface/src/method_channel/method_channel_firebase_auth.dart:447)
E/flutter (24141): <asynchronous suspension>
E/flutter (24141): #1      FirebaseAuth.signInWithCredential (package:firebase_auth/src/firebase_auth.dart:455)
E/flutter (24141): <asynchronous suspension>
E/flutter (24141): #2      _LoginScreenState.signInWithFacebook (package:DVH/pages/login.dart:220)
E/flutter (24141): <asynchronous suspension>

Steps to reproduce

Steps to reproduce the behavior:

  1. create a sample project

  2. setup firebase auth and social auth with firebase (facebook)

  3. try to signin with your facebook *for me even for the first time it didn't work, because I was checking for emailVerified to let the user sign in. so, I believe the account was created and after first approach now I can't login.

  4. See error or incorrect behavior

Expected behavior

should let users log in with having only one account instead of having multiple accounts.

Additional context

Add any other context about the problem here. here is code snippet: 

 Future<void> signInWithFacebook() async {
    debugPrint("logging in with fb");
    setLoading(true);
    var provider = Provider.of<AppProvider>(context, listen: false);
    var dbProvider = Provider.of<DBProvider>(context, listen: false);

    final LoginResult result = await FacebookAuth.i.login(permissions: [
      'email',
      'public_profile'
    ]); // by default we request the email and the public profile

    if (result.status == LoginStatus.success) {
      // you are logged
      final AccessToken accessToken = result.accessToken!;
      final firebaseAuthCred = FacebookAuthProvider.credential(
        accessToken.token,
      );
      UserCredential user = await FirebaseAuth.instance.signInWithCredential(
        firebaseAuthCred,
      );
      debugPrint(user.user.toString());
      if (user.user!.email != null) {
        debugPrint('user $user');
        debugPrint("addtional ${user.additionalUserInfo}");
        await getUserDetails(user, provider, dbProvider, 'Facebook');
      } else {
        socialLoginMsg = 'Can\'t login with Facebook at the moment';
        setLoading(false);
      }
    } else {
      setLoading(false);
      debugPrint("FB LOGIN FAILED ${result.status} ${result.message}");
      FirebaseCrashlytics.instance
          .log("FB login result: ${result.status} ${result.message}");
      setState(() {
        socialLoginMsg = 'An error occured.';
      });
    }
  }

@SebghatYusuf Are you logging in with Google account first and then with Facebook ? If so, then the exception you are getting is an expected behavior. For more details, check this issue comment and see if it helps to resolve your issue.

SebghatYusuf commented 2 years ago

@darshankawar, as I can see, this comment says after linking it works fine, now how can I link these two Google & Facebook auth providers?

SebghatYusuf commented 2 years ago

Was able to link between those two providers and now I can log in using Facebook & Google with having the same account.
