修复 Listview 上方的标题

如何解决修复 Listview 上方的标题

我正在开始使用 Flutter 并制作一个练习应用程序。我的代码很乱，但我稍后会调整它。

[我想做的是][1]

[我被困在什么][2]

我正在寻找的是列表视图项目上方的固定标题？

和

我们如何才能完美地对齐一行以使其与标题对齐？

我知道我的要求很高，但我们热烈欢迎任何有用的东西。

  @override
  _State createState() => _State();
}

class _State extends State<HomeScreen> {
  static bool isChecked = false;
  static DateTime Now = new DateTime.Now();
  // List<bool> _data = [true,true,true];

  List<Map<String,Object>> myList = [
    {
      'text': 'First','checkBoxes': [
        {DateTime(Now.year,Now.month,Now.day).toString(): isChecked},{DateTime(Now.year,Now.day - 1).toString(): isChecked},Now.day - 2).toString(): isChecked},Now.day - 3).toString(): isChecked},Now.day - 4).toString(): isChecked},Now.day - 5).toString(): isChecked},Now.day - 6).toString(): isChecked},]
    },{
      'text': 'Second',];

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        backgroundColor: Colors.greenAccent[400],title: Text('HabitTracker'),actions: <Widget>[
          IconButton(
            icon: Icon(Icons.add),onpressed: () {
              print('pressed add');
            },),IconButton(
            icon: Icon(Icons.filter_list_rounded),onpressed: () {
              print('pressed filter');
            },IconButton(
            icon: Icon(Icons.more_vert),onpressed: () {
              print('pressed menu');
            },],body: Container(
        child: ListView.builder(
          scrollDirection: Axis.vertical,itemCount: myList.length,itemBuilder: (context,index) {
            return Container(
              child: Column(
                children: [
                  Container(
                    padding: EdgeInsets.only(
                      right: 20,left: 20,margin: EdgeInsets.only(top: 10),height: 50,decoration: Boxdecoration(
                      color: Colors.greenAccent[400],borderRadius: BorderRadius.only(
                          bottomLeft: Radius.circular(20),topLeft: Radius.circular(20)),child: ListView(
                      scrollDirection: Axis.horizontal,children: [
                        Center(child: Text(myList[index]['text'])),_buildCheckBoxes(index),)
                ],);
          },);
  }

  Widget _buildCheckBoxes(int index) {
    List<Widget> list = new List();
    Widget cb;

    for (int i = 0;
        i < (myList[index]['checkBoxes'] as List<Map<String,Object>>).length;
        i++) {
      cb = CheckBox(
        value: (myList[index]['checkBoxes'] as List<Map<String,Object>>)[i]
            [DateTime(Now.year,Now.day - i).toString()],onChanged: (bool value) {
          setState(() {
            // need to update _data[?]
            (myList[index]['checkBoxes'] as List<Map<String,Object>>)[i]
                [DateTime(Now.year,Now.day - i).toString()] = value;
          });
        },);
      list.add(cb);
    }

    return Row(mainAxisAlignment: MainAxisAlignment.center,children: list);
  }
}```
