Recently encountered minor errors

1. Log().debug('this transport not be realsed, will realse $uuid'); Do not use $uuid, which will cause an error:

NoSuchMethodError: Class 'Log' has no instance method 'call'.

2. A previous way of writing

    try {
      res = await callResponse.timeout(Duration(seconds: 3)).firstWhere((r) => r.isNotEmpty && r[3] == params.opcode);

    } on TimeoutException catch (e) {
      Log.error('请求超时: $e');
    }
    return getCallResInfo(res, params);

    Timer timer = Timer(Duration(seconds: 5), () {
      subscription.cancel();
      if (!completer.isCompleted) {
        Log.error('请求超时: Stream was closed due to timeout = 5s.');
        completer.complete(res);
      }
    });

    subscription = callResponse.listen((r) {
      print('gs.response :$r');
      if (r.length > 3 && r[3] == params.opcode!) {
        timer.cancel(); // 取消计时器
        subscription.cancel(); // 取消订阅
        res = getCallResInfo(r, params);
        completer.complete(res);
      }
    });

 Combining the two usages

 It can be used, but the effect is not good, discard it;

The final choice is:

 try{
      print('call 无法进行数据处理 之前的configuredDate');
    final value = configuredDate(data as CallParams);
    // await transport.nofitySubscription!;
    transport.writeCharacteristic.write(value);
    res = await getCallResponse(data as CallParams);
    }catch(e){
      res = CallResInfo(false, null, null);
      Log.error('获取数据有误: ',e);
    }finally{
      runCompleter = null;
    }

   return {'res':'res'};
  }


  Future<CallResInfo> getCallResponse(CallParams params) async{
    late StreamSubscription subscription;
    var completer = Completer<CallResInfo>();
    CallResInfo res = CallResInfo(false, null, null);

    var r = await runCompleter!.future;
      if (r.length > 3 && r[3] == params.opcode!) {
        res = getCallResInfo(r, params);
        completer.complete(res);
      }else{
        Log.error('runCompleter: wrong .');
      }

    return completer.future; // 添加返回语句
  }
