  final MoYoungBle _blePlugin = MoYoungBle();
  final List<BleScanBean> _deviceList = [];
  
  @override
  void initState() {
    super.initState();
    subscriptStream();
  }
  
  void subscriptStream() {
    _streamSubscriptions.add(
      _blePlugin.bleScanEveStm.listen(
        (BleScanBean event) async {
          setState(() {
            if (event.isCompleted) {
              //Scan completed, do something
            } else {
              _deviceList.add(event);
            }
          });
        },

    super.dispose();
    for (final subscription in _streamSubscriptions) {
      subscription.cancel();
    }

  // Scanning bluetooth devices
  void startScan() {
    if (!mounted) return;
    _blePlugin.startScan(10*1000).then((value) => {
      setState(() {
        // Do something.
        print(value ? "Scanning" : "Have not started");
      })
