flutter_nfc_kit 1.0.0

Flutter NFC Kit #

pub version

Yet another plugin to provide NFC functionality on Android and iOS.

This plugin supports:

  • read metadata of tags / cards complying with:
    • ISO 14443-4 Type A & Type B (NFC-A / NFC-B / Mifare Classic / Mifare Plus / Mifare Ultralight / Mifare Desfire)
    • ISO 18092 (NFC-F / Felica)
    • ISO 15963 (NFC-V)
  • transceive commands with tags / cards complying with:
    • ISO 7816 Smart Cards (layer 4, in APDUs)
    • other device-supported technologies (layer 3, in raw commands, Android only)

Note that due to API limitations not all operations are supported on both platforms.

Setup #

Thank nfc_manager plugin for these instructions.

Android #

iOS #

Usage #

Simple example:

import 'package:flutter_nfc_kit/flutter_nfc_kit.dart';

var availability = await FlutterNfcKit.nfcAvailability;
if (availability != NFCAvailability.available) {
    // oh-no

var tag = await FlutterNfcKit.poll();
if (tag.type == NFCTagType.iso7816) {
    var result = await FlutterNfcKit.transceive("00B0950000");
await FlutterNfcKit.finish();

A more complicated example can be seen in example dir.

Refer to the documentation for more information.
