[local_auth] After the face authentication is completed, if you click the Cancel button, a crash occurs.

[JosephNK]

If you press the Cancel button after completing Face authentication, the crash below always occurs, and the status is Authentication in progress.

• local_auth: ^2.1.0

Code sample

try {
  LocalAuthentication? auth = LocalAuthentication();
  final bool didAuthenticate = await auth.authenticate(
                              localizedReason:  'Please authenticate',
                              options: const AuthenticationOptions(),
                            );
} on PlatformException catch (e) {
  Logging.e('error: $e');
}

Hi @JosephNK, Thanks for filing the issue. Please share a minimal and complete code sample along with the output of flutter doctor -v and flutter run -v(in a text file as the output will be long)

Without additional information, we are unfortunately not sure how to resolve this issue. We are therefore reluctantly going to close this bug for now. If you find this problem please file a new issue with the same description, what happens, logs and the output of 'flutter doctor -v'. All system setups can be slightly different so it's always better to open new issues and reference the related ones. Thanks for your contribution.
