Flutter 我如何从Flatter中的数据结构内容创建小部件？

这就是我想要实现的目标：

我已经创建了bellow类来初始化和存储对象

class WidgetItem {
  SliverList sliverList;
  List<StatefulBuilder> statefulBuilder;
  WidgetItem(this.sliverList, this.statefulBuilder);
}

---

我想你们可以看看包装

 List<StatefulBuilder> listOfIn = [];
 List<StatefulBuilder> listOfOut = [];

 List<WidgetItem> listOfItems = [];

  listOfItems.add(new WidgetItem(
    SliverList(
      delegate: SliverChildListDelegate([
        ListTile(
          title: "Header 1",
        ),
      ]),
    ),
    listOfIn));

 listOfItems.add(new WidgetItem(
    SliverList(
      delegate: SliverChildListDelegate([
        ListTile(
          title: "Header 2",
        ),
      ]),
    ),
    listOfIn));

return new Scaffold(
       body: CustomScrollView(
             slivers: <Widget>[
             //show all objects from listOfObjects
             list all items from `listOfItems`

      ]
   ))
