onNeedUnlock is called over and over again

There's an issue making onNeedUnlock is called over and over again.

Reproduce:

Run the example
Install local_auth

Modify onNeedUnlock as below

onNeedUnlock: (secure) async {
      print(
          'need unlock maybe use biometric to confirm and then sercure.unlock() or you can use the lockedBuilder');
      try {
        final LocalAuthentication auth = LocalAuthentication();

        var authResult = await auth.authenticate(
          localizedReason: 'ZZZ',
          options: AuthenticationOptions(
            biometricOnly: false,
          ),
        );
        if (authResult) {
          secure?.unlock();
          return SecureApplicationAuthenticationStatus.SUCCESS;
        }
        else {
          return SecureApplicationAuthenticationStatus.FAILED;
        }
      } catch (e) {
        return SecureApplicationAuthenticationStatus.FAILED;
      }
      return null;
    },

If the app asks for FaceID => face not matched => Cancel => onNeedUnlock is called over and over.

This is because of appstate changed to resumed when face id is dismissed. I don't know this is a bug or not, but I think onNeedUnlock should not work like that. Currently I put a small delay after .authenticate() to workaround this.
