Question

我正在尝试从复选框选择中创建ID和名称的列表，我想在navigator.pop中传递该数组列表，但是以某种方式我无法做到这一点。？

我试图创建模型并将其放在列表对象中，这样可以给我选定的值在列表或数组中，但是我在最后一个（comma（，））上得到了它

我的复选框和代码以创建列表并将其传递到navigator.pop。

THIS IS MAIN PAGE WHERE I WANT TO GET AND REDIRECT TO SECOND LIST PAGE.

var tempRoomFace;

getRoomFaceData() async {
    tempRoomFace = await Navigator.push(
        context, MaterialPageRoute(builder: (context) => RoomFacilities()));
        for (int i = 0; i < areaDataResult.length; i++) {
      _selectedroom = _selectedroom + tempRoomFace[i].name + ", ";
      _selectedroomID = _selectedroomID + tempRoomFace[i].id + ", ";
      print("selected rooms : $_selectedroomID");
    }
  }


THIS IS LIST PAGE... TO CREATE LIST

------------------ code for passing value  ---------------------

List<RoomFacilityModel.Message> tempRoomData =
      List<RoomFacilityModel.Message>();
  //
  List<RoomFacilityModel.Message> roomListOBJ =
      List<RoomFacilityModel.Message>();

onPressed: () {
                  Navigator.pop(context, tempRoomData);
                  for (int i = 0; i < tempRoomData.length; i++) {
                    print(
                        "City List : ${tempRoomData[i].fcid} + ${tempRoomData[i].name} ");
                  }
                },

-------------------   Code for checkbox  ------------------

Container(
                child: CheckboxListTile(
                    title: Row(
                      children: <Widget>[
                        Container(
                          padding: EdgeInsets.all(5),
                          decoration: BoxDecoration(
                            borderRadius: BorderRadius.circular(3),
                            color: Colors.black,
                          ),
                          height: 26,
                          width: 26,
                          child: Image.network(
                            roomListOBJ[index].icon,
                          ),
                        ),
                        SizedBox(width: 10),
                        Text(roomListOBJ[index].name),
                      ],
                    ),
                    value: roomListOBJ[index].isCheck,
                    onChanged: (bool value) async {
                      //
                      setState(() {
                        roomListOBJ[index].isCheck = value;
                        if (value) {
                          tempRoomData.add(RoomFacilityModel.Message(
                              fcid: roomListOBJ[index].fcid,
                              name: roomListOBJ[index].name));
                        } else {
                          tempRoomData.removeAt(index);
                        }
                      });
                    }),
              );
