CheckBox not displaying in future builder

Can someone explain to me why would this happened?

I would like to display the check status based on the value returned from FutureBuilder.

If snapshot.data is 1, it will display checkbox with checked status. Otherwise will allow user to tick.

I have 6 check boxes, the first 3 check boxes is checked, the others no. But it only display the last 3 check boxes. The checkbox with checked status not going to show.

 ...item['questions'].asMap().entries.map((items) {
                    return TableRow(children: [
                      Padding(
                          padding: EdgeInsets.all(10),
                          child: Text(items.value['name'])),
                      FutureBuilder(
                          future: _workOrderBloc.selectAnswer(
                              items.value['id'], "MC"),
                          builder: (context, snapshot) {
                            return Checkbox(
                                tristate: true,
                                onChanged: snapshot.data == "1"
                                    ? null
                                    : (answer) {
                                      },
                                value: snapshot.data == "1"
                                    ? true
                                    : answers[items.value['id']] ?? false);
                          }),
                    ]);
                  }).toList()

But after reload, the check box with check status will show. How to make it show before reload?
