Flutter-如何在Iconbutton小部件旁边创建迷你模式？

Question

我想在三个点图标旁边创建一个迷你模式开口。

创建该建议的最佳方法？

IconButton(
 icon: const Icon(Icons.more_horiz),
 onPressed: () { 
   // magic here?
 }),

PopupMenuButton<Menu>(
              // Callback that sets the selected popup menu item.
              onSelected: (Menu item) {
                setState(() {
                  _selectedMenu = item.name;
                });
              },
              itemBuilder: (BuildContext context) => <PopupMenuEntry<Menu>>[
                    const PopupMenuItem<Menu>(
                      value: Menu.itemOne,
                      child: Text('Item 1'),
                    ),
                    const PopupMenuItem<Menu>(
                      value: Menu.itemTwo,
                      child: Text('Item 2'),
                    ),
                    const PopupMenuItem<Menu>(
                      value: Menu.itemThree,
                      child: Text('Item 3'),
                    ),
