Read NFC

This function will return a promise when a read occurs, till that very moment the reading session is open. The promise will return a NfcData model, this model contains:

  • id > id of the tag
  • content > content of the tag
  • error > if any error occurs
Future<void> startNFC() async {
    setState(() {
      _nfcData = NfcData();
      _nfcData.status = NFCStatus.reading;

    print('NFC: Scan started');

    print('NFC: Scan readed NFC tag');
    FlutterNfcReader.read.listen((response) {
      setState(() {
        _nfcData = response;

Stop NFC

Future<void> stopNFC() async {
    NfcData response;

    try {
      print('NFC: Stop scan by user');
      response = await FlutterNfcReader.stop;
    } on PlatformException {
      print('NFC: Stop scan exception');
      response = NfcData(
        id: '',
        content: '',
        error: 'NFC scan stop exception',
        statusMapper: '',
