🐛 [firebase_auth_desktop] Firebase authentication not working !!

[Jazzel]

Bug report

SignIn Request With Flutter
It is working in the mobile build but when I switch to the desktop build it shows:
flutter : UnimplementedError

Authentication (SignIn Function)

Future<User?> signInWithEmailPassword(String email, String password) async {
  User? user;
  print('running');

  try {
    UserCredential userCredential = await _auth.signInWithEmailAndPassword(
      email: email,
      password: password,
    );
    print('user');
    user = userCredential.user;


    if (user != null) {
      uid = user.uid;
      userEmail = user.email;

      SharedPreferences prefs = await SharedPreferences.getInstance();
      await prefs.setBool('auth', true);
    }
  }

Having same issue.

[JulioCesarSF]

Doesn't look related to this package.
I just did a new project and both Anonymously and EmailPassword auth types are working fine.

My dependencies:
dependencies:

  firebase_auth: ^3.3.18
  firebase_auth_desktop: ^1.0.0
  firebase_core: ^1.17.0
  firebase_core_desktop: ^1.0.0

Did you try running flutter clean and flutter pub cache repair?
