Bug report

Describe the bugT The firebase app is being initialized in the main. The code worked as of last week. The error is thrown at sign-up or login. The error persists on multiple dev environment and test devices. The issue happens on the Emulator and the Live settings. I do not know what changed.

Steps to reproduce

Just try logging in.

Expected behavior

The app should log in or through a non-null error.

Sample project

My main()

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  await Firebase.initializeApp();

  if (IS_EMULATOR) {
    if (!kIsWeb) {
      String host = !Platform.isAndroid ? 'localhost' : '10.0.2.2';
      await FirebaseAuth.instance.useAuthEmulator(host, 9099);
      FirebaseFirestore.instance.settings = Settings(
        host: '$host:8080',
        sslEnabled: false,
        persistenceEnabled: false,
      );
      await fbStorage.FirebaseStorage.instance.useStorageEmulator(host, 9199);
      if (Platform.isIOS) timeDilation = 2.0;
    } else {
      await FirebaseAuth.instance.useAuthEmulator('localhost', 9099);
      FirebaseFirestore.instance.useFirestoreEmulator('localhost', 8080);
      await fbStorage.FirebaseStorage.instance
          .useStorageEmulator('localhost', 9199);
    }
  }

  runApp(const MyApp());
}

My auth function:

void _submitLogin(String email, String password) async {
      final _auth = FirebaseAuth.instance;
      UserCredential user;
      final firestore = FirebaseFirestore.instance;
      bool haveDaysSelected = !_daysOfWeek.values.every((element) => !element);
      bool haveImage = _profileImage != null;
      bool haveCourts = _tennisCourts.isNotEmpty;

      if (_isSignup) {
        user = await _auth.createUserWithEmailAndPassword(
          email: email,
          password: password,
        );

       /*unrelated Firestore logic*/

        return;
      }

await _auth.signInWithEmailAndPassword(email: email, password: password);

I have uploaded an internal testing app to playstore. Installed in my local phone through playstore to test it out seems not working anymore with firebase google_sign_in. Waiting for the app to finish Pre-launch report to see how it works. But for sure something not right. My local dev version apps works fine on android, web.

muddi900 commented 3 years ago

The issue persists when firebase_core is updated the latest version(1.8.0)

darshankawar commented 3 years ago

@muddi900 You seem to be on a bit older version of the framework and auth plugin. Please upgrade them to latest and try again. Also, if issue persists, provide full verbose log containing the error.

muddi900 commented 3 years ago

@darshankawar The issue persists even after updating all firebase plugins.

@muddi900 Do you get this error while running on a physical device too ? or just an emulator or firebase emulator only ? I just tried with official plugin example with which I was able to authenticate and run properly. Can you try the same and see if you still get same behavior ?

muddi900 commented 3 years ago

The error was due to me passing through a null value to the password field. So the bug is in the error message. If the error message was more clear, it would have been a lot of time.

darshankawar commented 3 years ago

Thanks for identifying root-cause. Can you provide a code snippet for passing through a null value to the password field that we can take a look at and verify ? Does it only happen for password field or for any field ?

muddi900 commented 3 years ago

I was just passing a null value to the log- call back.

Keeping it open and labeling for team's radar.

russellwheatley commented 2 years ago

This is a required field. See here. You cannot pass null as a password.

muddi900 commented 2 years ago

While the solution is provided for the root cause, it would be impossible to guess just by reading the error message. The exception should make it clear that the Password field is null.

The issue might be the code, but it would require a lot of work just to figure it out.
