  1. Create a beautiful passcode lock view simply.
PasscodeScreen(
  title: title,
  passwordEnteredCallback: _onPasscodeEntered,
  cancelLocalizedText: 'Cancel',
  deleteLocalizedText: 'Delete',
  shouldTriggerVerification: _verificationNotifier.stream,  
);
Dart
  1. Passcode input completed callback.
_onPasscodeEntered(String enteredPasscode) {
  
}
Dart
  1. Notify passcode screen if passcode correct or not
final StreamController<bool> _verificationNotifier = StreamController<bool>.broadcast();

_onPasscodeEntered(String enteredPasscode) {
  bool isValid = '123456' == enteredPassword;
  _verificationNotifier.add(isValid);
}
Dart

Don't forget to close a stream

@override
void dispose() {
  _verificationNotifier.close();
  super.dispose();
}
Dart
