    String response;
    try {
      final String result = await FlutterNfcReader.read;
      if (result != null) {
        response = '';
      } else {
        response = result;
      }
    } on PlatformException {
      response = '';
    }
    setState(() {
      _nfcActive = true;
      _nfcData = response;
    });
  }

Stop NFC

  Future<Null> NfcStop() async {
    bool response;
    try {
      final bool result = await FlutterNfcReader.stop;
      response = !result;
    } on PlatformException {
      response = false;
