🐛 [firebase_auth] throw PlatformException(code: errorCode, message: errorMessage, details: errorDetails);

SirMajed commented 3 years ago

Hello, I have a weird problem, I have an existed user in my firebase auth. so when I register a new user the code in try and catch the code for the user registration:

AuthResult res;
    try {
      res = await _instance.createUserWithEmailAndPassword(
          email: account.getEmail(), password: account.getPassword());
      (account as User).id = res.user.uid;

      await Firestore.instance
          .collection('Users')
          .document((account as User).id)
          .setData((account as User).toJson());

      await signIn(account);
    } catch (e) {
      signOut();
      rethrow;
    }

and in the UI, I also have try and catch for firebase exception class that I already made that contains the error codes for firebase auth and firestore.

try {
  User user = new User(
    email: _email,
    password: _password,
    name: _name);
  await user.register();
  Navigator.of(context).pop();
}
on PlatformException
catch (exception) {
  String msg = FirebaseException
    .generateReadableMessage(exception);
  MyBar.customFlushBar(
    context: context,
    message: msg,
    icon: Icons.warning_amber_rounded);
}
}

But the problem is that the error is not even catched and the system stopped at this line in debug: Screenshot_8

I just want it to display the snackbar error instead of the system stop working, I'm sorry for my English

Hi @SirMajed What exactly is the problem here? Could you provide expected vs actual behavior? For example, this works when trying to register an existing email:

  // Example code for registration.
  void _register() async {
    try {
      final User user = (await _auth.createUserWithEmailAndPassword(
        email: _emailController.text,
        password: _passwordController.text,
      ))
          .user;
      if (user != null) {
        setState(() {
          _success = true;
          _userEmail = user.email;
        });
      } else {
        _success = false;
      }
    } catch (e) {
      print(e.runtimeType);
      print("caught $e");
    }
  }

I/flutter ( 7702): FirebaseAuthException
I/flutter ( 7702): caught [firebase_auth/email-already-in-use] The email address is already in use by another account.

Thank you

Thank you

Thank you for your answer, It not supposed to freeze the IDE, it supposed to gives an error and continue. because when the user trying to delete his account, he must provide his password to reauthenticate, so if I provide a wrong password it should give a snackbar with error but instead the vscode IDE freezes, Check my next comment pleae

Here also didnt worked for me when user trying to delete his account, the vscode freezes and gives platform exception

Code for UI

try {
  await Authentication.deleteAccount(
    email: user.getEmail(),
    password: _password,
    userID: user.getID(),
  );
  MyBar.customFlushBar(
    context: context,
    message: 'Account deleted!',
    icon: Icons.check);
  Navigator.pop(context);
}
on PlatformException
catch (ex) {
  String msg = FirebaseException
    .generateReadableMessage(ex);
  MyBar.customFlushBar(
    context: context,
    message: msg,
    icon: Icons.check);
}

Delete account method

static Future deleteAccount(
      {String userID, String password, String email}) async {
    print(email);
    try {
      FirebaseUser user = await _instance.currentUser();
      AuthCredential credentials =
          EmailAuthProvider.getCredential(email: email, password: password);
      print(user);
      AuthResult result = await user.reauthenticateWithCredential(credentials);
      await Database.deleteUserDocuments(userID); // called from database class
      await result.user.delete();
      return true;
    } on FirebaseException catch (e) {
      print(e.toString());
      return Future.error(e);
    }
  }

Well suddenly it was from the debugging mode, I was able to solve it by unchecking the 'Uncaught Exceptions' checkbox. it runs fine and the FirebaseException was caught. The problem is coming from VsCode debugger
