Flutter Firebase change password of user with 2FA enabled

Question

When i sign in with 2FA (email provider, phone provider) i just do signInWithEmailAndPassword , then i catch FirebaseAuthMultiFactorException , get MultiFactorResolver to resolve second factor and sign in successfully. Similar for sign up. The problem arises when i try to modify user data, like to change password.

I tried the same flow as we do for sign in/ sign up flow, but it doesn't work, it returns FirebaseException instead of FirebaseAuthMultifactorException :

Future<void> changePassword({required String email, required String password, required String newPassword}) async{
    final user = _firebaseAuth.currentUser!;
    try{
      final cred = EmailAuthProvider.credential(email: email, password: password);
      await user.reauthenticateWithCredential(cred);
    } on FirebaseAuthMultiFactorException catch(e){
      log("i need to get resolver here but this line is never executed");
    } on FirebaseException catch(e){
      log("firebase exception, which doesn`t provide resolver");
      rethrow;
    }
  }

The output is following:

[log] firebase exception, which doesn`t provide resolver

Answer 1

That was flutter firebase-sdk issue that was fixed in latest versions of firebase_auth package
