Usage

import 'package:nfc_manager/nfc_manager.dart';
import 'package:nfc_manager/nfc_ndef.dart';

// Start a session and register onTagDiscovered callback.
await NfcManager.instance.startSession(
  onTagDiscovered: (NfcTag tag) async {
    if (tag.ndef == null) {
      print('Tag is not NDEF formattable');
      return;
    }

    if (tag.ndef.cachedNdefMessage == null) {
      print('NDEF is in INITIALIZED state');
      return;
    }

    // Now you can get an NDEF Message that cached at the time of discovery.
    NfcNdefMessage cachedMessage = tag.ndef.cachedNdefMessage;

    // Create an NDEF Message you want to write.
    NfcNdefMessage message = NfcNdefMessage([
      NfcNdefRecord.createText('Hello World'),
    ]);

    // Write an NDEF Message on this tag.
    await tag.ndef.writeNdef(message);

    // We can also refer to tag-specific data.
    // This data will be used by this plugin in the future.
    Map<String, dynamic> data = tag.additinalData;

    // Should stop a session at the appropriate time.
    await NfcManager.instance.stopSession();
  },
