@override

        widget.password, widget.deviceCount, widget.isBroadcast);
    super.initState();
  }
  
@override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        leading: IconButton(
            icon: Icon(Icons.arrow_back),
            onPressed: () {

        child: StreamBuilder<ESPTouchResult>(
          stream: _stream,
          builder: (context, AsyncSnapshot<ESPTouchResult> snapshot) {
            if (snapshot.hasError) {
              return error(context, 'Error in StreamBuilder');
            }
            switch (snapshot.connectionState) {
              case ConnectionState.active:
                _results.add(snapshot.data!);
                return resultList(context, ConnectionState.active);

              case ConnectionState.done:
                if (snapshot.hasData) {
                  _results.add(snapshot.data!);
                  return resultList(context, ConnectionState.done);
                } else
                  return noneState(context);
              case ConnectionState.waiting:
