推荐答案

您必须将抽屉子属性传递给ListView，然后在该ListView中使用ExpansionTile。看起来像这样：

You have to pass the drawers child property a ListView, and in that ListView you can then use an ExpansionTile. That would look something like this:

Drawer(
  child: ListView(
    children: <Widget>[
      ExpansionTile(
        title: Text("Expansion Title"),
        children: <Widget>[Text("children 1"), Text("children 2")],
      )
    ],
  ),
);
