CodePudding user response：

  return Drawer(
          child: SafeArea(
              child: Column(
            children: [
              for (int i = 0; i < 5; i  ) buildExpansionTile(i),
            ],
          )),
        );


 Widget buildExpansionTile(int position) {
    if (position != 4) {
      return ListTile(
        title: Text("Child Category $position"),
      );
    } else {
      return ExpansionTile(
        title: Text("Parent Category 1"),
        leading: Icon(Icons.person), //add icon
        childrenPadding: EdgeInsets.only(left: 60), //children padding
        children: [
          ListTile(
            title: Text("Child Category 1"),
          ),
          ListTile(
            title: Text("Child Category 2"),
          ),
        ],
      );
    }
  }
}
