Flutter NFC Reader

A new flutter plugin to help developers looking to use internal hardware inside iOS or Android devices for reading NFC tags.

The system activate a pooling reading session that stops automatically once a tag has been recognised. You can also trigger the stop event manually using a dedicated function.


Add to pubspec.yaml:

      url: git://github.com/matteocrippa/flutter-nfc-reader.git
      ref: master

and then run the shell

flutter packages get

last step import to the project:

import 'package:flutter_nfc_reader/flutter_nfc_reader.dart';

How to use

Android setup

<uses-permission android:name="android.permission.NFC" />
        android:required="true" />

iOS Setup

Atm only Swift based Flutter project are supported.

  • Enable Capabilities / Near Field Communication Tag Reading.
  • Info.plist file, add Privacy - NFC Scan Usage Description with string value NFC Tag.

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 {
    NfcData response;

    setState(() {
      _nfcData = NfcData();
      _nfcData.status = NFCStatus.reading;

    print('NFC: Scan started');

    try {
      print('NFC: Scan readed NFC tag');
      response = await FlutterNfcReader.read;
    } on PlatformException {
      print('NFC: Scan stopped exception');
    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: '',
      response.status = NFCStatus.error;

    setState(() {
      _nfcData = response;
