[Flutter] flutter multiple api calls ; 여러개의 response 처리하기

  Future _fetchData() async {
    setState(() {
      _showLoading = true;
    });

    final responses = await Future.wait([
      httpHelper.fetchWorkData(widget.userId, widget.selectedDate, "day"),
      httpHelper.fetchCutivationStepData(widget.selectedDate),
      httpHelper.fetchFieldListData(widget.userId),
      httpHelper.fetchWorkListData(),
      httpHelper.fetchPestListData(),
      httpHelper.fetchDisorDerListData(),
    ]);

    setState(() {
      todayDataList = responses[0];
      cultivationStepData = responses[1];
      fieldListData = responses[2];
      workListData = responses[3];
      pestListData = responses[4];
      disorderListData = responses[5];
    });

    setState(() {
      _showLoading = false;
    });
    print(fieldListData);
  }

여러개의 요청을 리스트에 받은 후 객체에 요청 결과를 각 각 할당하면 끝.
