Сброс опции радио, выбранной, когда dateRange выбран в Flutter

Question

Моя панель инструментов имеет нижнюю таблицу, похожую на this , которая состоит из параметров радио и средства выбора даты. Что я хочу сделать, если выбран диапазон дат, то параметр радио отменен, я хочу, чтобы любойбыть выбран не оба. дайте мне знать, если есть какие-либо изменения, спасибо

Здесь я добавляю свой код

import 'package:flutter/material.dart';
import 'package:datetime_picker_formfield/datetime_picker_formfield.dart'; //USED WHEN DATE ENABLED
import 'package:intl/intl.dart';

class DashboardFilter extends StatefulWidget {
  @override
  _DashboardFilterState createState() => _DashboardFilterState();

  final ValueChanged<List<Map<Object, Object>>> parentAction;
  var globalData;
  Map<String, int> timeSelected;

  DashboardFilter(
      {Key key,
      this.parentAction,
      this.timeSelected,
      this.globalData})
      : super(key: key);
}

class _DashboardFilterState extends State<DashboardFilter> {
  var radioSelected;

  @override
  void initState() {
    super.initState();
    radioSelected = widget.timeSelected.keys.firstWhere(
        (k) => widget.timeSelected[k] == 1,  //here I am setting the default radio button value
        orElse: () => null);
  }

  void showModalSheet() {
    List<Map<String, Object>> timeData = List<Map<String, Object>>();
    Map<String, Object> tData = Map<String, Object>();
    widget.globalData['dashboardTimestamps']
        .map((data) => {
              tData = data,
              timeData.add(tData),
            })
        .toList();

}

В приведенном выше коде я получаю отображаемое имя переключателя, нажимая API и сохраняя его вкарта, и я передаю значения конструктора этому классу из другого файла, т.е. выбранное время содержит: {"today": 1, "lastThirtyMinutes": 0, "lastOneHour": 0, "lastThreeHour": 0, "lastSixHour": 0, "lastTwelveHour": 0, "lastTwentyFourHour": 0};

globalData содержит: карту, для которой выбирается displayName для радиокнопки.

т.е.

"dashboardTimestamps": [
        {
            "id": "today",
            "displayId": "Today"
        },
        {
            "id": "lastThirtyMinutes",
            "displayId": "Last 30 Minutes"
        },
        {
            "id": "lastOneHour",
            "displayId": "Last Hour"
        },
        {
            "id": "lastThreeHour",
            "displayId": "Last 3 Hour"
        },
        {
            "id": "lastSixHour",
            "displayId": "Last 6 Hour"
        },
        {
            "id": "lastTwelveHour",
            "displayId": "Last 12 Hour"
        },
        {
            "id": "lastTwentyFourHour",
            "displayId": "Last 24 Hour"
        }
