Start Liveness Verification

Calling startFaceLiveness

To start the liveness verification process, initialize FaceLiveness with mobileToken and personId, then call start() and handle events using a listener:

void startSDK() {
  final stream = _faceLiveness.start();
  _setupFaceLivenessListener(stream);
}

void _setupFaceLivenessListener(Stream<FaceLivenessEvent> stream) {
  stream.listen((event) {
    if (event is FaceLivenessEventConnecting) {
      print('Connecting to FaceLiveness...');
    } else if (event is FaceLivenessEventConnected) {
      print('Connected to FaceLiveness.');
    } else if (event is FaceLivenessEventClosed) {
      print('SDK closed by the user.');
    } else if (event is FaceLivenessEventSuccess) {
      print('Success! SignedResponse: ${event.signedResponse}');
    } else if (event is FaceLivenessEventFailure) {
      print(
        'Failure! Error type: ${event.errorType}, '
        'Error description: ${event.errorDescription}',
      );
    }
  });
}
