[firebase_auth] Unhandled Exception: PlatformException(ERROR_INVALID_VERIFICATION_CODE)

[definitelyme]

Describe the bug

E/flutter (10238): [ERROR:flutter/lib/ui/ui_dart_state.cc(166)] Unhandled Exception: PlatformException(ERROR_INVALID_VERIFICATION_CODE, The sms verification code used to create the phone auth credential is invalid. Please resend the verification code sms and be sure use the verification code provided by the user., null)

I cannot handle the above exception using try / catch when an invalid SMS verification code is passed to the firebaseUser.updatePhoneNumberCredential(credential) method

To Reproduce
Steps to reproduce the behavior:

1. Authenticate user using FirebaseAuth

FirebaseAuth.instance.verifyPhoneNumber(phoneNumber: "+XXX XXX XX XXXX");

2. Get an instance of the Authenticated User

var firebaseUser = await FirebaseAuth.instance.currentUser();

4. Get Phone credentials & update phone number

try {
    final credential = PhoneAuthProvider.getCredential(verificationId: '-------', smsCode: 'WRONG CODE');
    firebaseUser.updatePhoneNumberCredential(credential);
} catch (e) {
    print("Exception caught => $e");
}

Expected behavior
The try / catch block should handle the exception rather than rethrowing / ignoring it.
In my case, a debug print in the console with the exception ->

Exception caught => [ERROR:flutter/lib/ui/ui_dart_state.cc(166)] Unhandled Exception: PlatformException(ERROR_INVALID_VERIFICATION_CODE, The sms verification code used to create the phone auth credential is invalid. Please resend the verification code sms and be sure use the verification code provided by the user., null)

Can you try the below syntax
try { // your firebase calls } on PlatformException catch (PlatformException e) { // do custom magic by acessing e.code and e.message for more information on it }

[definitelyme]

Can you try the below syntax
try { // your firebase calls } on PlatformException catch (PlatformException e) { // do custom magic by acessing e.code and e.message for more information on it }

(e) is already an instance of the Exception PlatformException.

'catch' must be followed by '(identifier)' or '(identifier, identifier)'.
No types are needed, the first is given by 'on', the second is always 'StackTrace'.

Here's what I did

void signInWithPhone(String phone) {
  // your firebase calls
  // Authenticate user with Firebase
  FirebaseAuth.instance.verifyPhoneNumber(
    phoneNumber: "+XXX XXX XX XXXX",
    timeout: Duration(seconds: 60),
    codeSent: (verificationId, [int token]) {
      // Perform action
      // Navigate to another screen & input CODE
    },
    codeAutoRetrievalTimeout: (verificationId) {},
    verificationCompleted: (credentials) => null,
    verificationFailed: (ex) => print("$ex"),
  );
  ...
}

void verifyCode(String verificationId, String code) async {
  try {
    var firebaseUser = await FirebaseAuth.instance.currentUser();

    final credential = PhoneAuthProvider.getCredential(verificationId: verificationId, smsCode: code);

    firebaseUser.updatePhoneNumberCredential(credential);
  } on PlatformException catch (e) {
    print("Exception caught => ${e.code}");
  }
}

// Call function "verifyCode" somewhere with an invalid verification code
verifyCode("---------", "WRONG CODE")

And it still throws the exception PlatformException(ERROR_INVALID_VERIFICATION_CODE) when an invalid verification code is used.

Hey 👋

Our rework of the firebase_auth plugin as part of the FlutterFire roadmap was published over a week ago with a ton of fixes and new features. Please could you try the new version and see if this is still an issue for you? If it is then please submit a new up to date GitHub issue.

See: https://firebase.flutter.dev/docs/auth/error-handling

For help migrating to the new plugins please see the new migration guide: https://firebase.flutter.dev/docs/migration

Having updated my version of firebase_auth and included the compulsory 'Firebase.initializeApp()' before using FlutterFire features. I still can not catch the exception - ERROR_INVALID_VERIFICATION_CODE.

New
I found a similar bug.
If User A verifies a phone number (+AAA AAA BB BBB) and User B attempts to update their profile using the same phone number above by calling firebaseUser.updatePhoneNumberCredential(credential); the thrown exception "account-exists-with-different-credential" is not caught by the try/catch block.

Example:

try {
    // Authenticate user using existing phone number credential
    final credential = PhoneAuthProvider.getCredential(verificationId: '-------', smsCode: 'VALID CODE');
    firebaseUser.updatePhoneNumberCredential(credential);
} catch (e) {
   // The exception is not caught here
    print("Exception caught => $e");
}
