初始化

     static const EventChannel _eventChannel = EventChannel(Constant.CHANNEL_NAME);
     StreamSubscription _streamSubscription;

     Future<void> init({Map<String, String> config}) async {
       await XindaluScanFlutter.init();
     }

     @override
      void initState() {

        // 初始化
        init();

        // 监听扫描数据
        _streamSubscription = _eventChannel.receiveBroadcastStream().listen((value) {
          try{
            XindaluDataResultModel result = XindaluDataResultModel.fromJson(json.decode(value));
            print("条码值:${result.code1}");  // 123456789
            print("状态:${result.scanState}"); // ok 成功  fail 失败
            print("条码类型:${result.scanBarcodeType}"); // -1 表示未知类型
          }catch(e,s){
              print(e);
              print(s);
          }
        });
      }

      @override
      void dispose() {
        _streamSubscription.cancel();
      }

        print("条码值:${result.code1}");
        print("状态:${result.scanState}"); // ok 成功  fail 失败
        print("条码类型:${result.scanBarcodeType}"); // -1 表示未知类型
      }catch(e,s){
          print(e);
          print(s);
      }
    });
  }

  //初始化
  Future<void> init({Map<String, String> config}) async {
    await XindaluScanFlutter.init();
  }

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: const Text('Plugin example app'),
