flutter_easy_nfc

flutter nfc库

安装

依赖:

flutter_easy_nfc: any

使用

导入库

import 'package:flutter_easy_nfc/flutter_easy_nfc.dart';

判断是否有nfc

await FlutterEasyNfc.isAvailable();

判断当前nfc是否打开

await FlutterEasyNfc.isEnabled();

启用nfc监听

await FlutterEasyNfc.startup();

停止nfc监听

await FlutterEasyNfc.shutdown();

监听nfc事件:

 FlutterEasyNfc.onNfcEvent((NfcEvent event) async {
       /// 目前支持两种标签: IsoDep和MifareClassic
      if (event.tag is IsoDep) {
        IsoDep isoDep = event.tag;
        await isoDep.connect();
        await isoDep.transceive("00a40000023f00");
        Uint8List file05 = await isoDep.transceive("00b0850000");
        await isoDep.transceive("00a40000023f01");
        Uint8List file15 = await isoDep.transceive("00b0950000");
        await isoDep.close();
        print(file05);
        print(file15);
      } else if (event.tag is MifareClassic) {
        MifareClassic m1 = event.tag;
        await m1.connect();
        await m1.authenticateSectorWithKeyA(0, "A0A1A2A3A4A5");
        print(await m1.readBlock(0));
        print(await m1.readBlock(1));
        print(await m1.readBlock(2));
        print(await m1.readBlock(3));
        await m1.close();
      }
    });
