PopupMenuItem<T> class Null safety

An item in a Material Design popup menu.

To show a popup menu, use the showMenu function. To create a button that shows a popup menu, consider using PopupMenuButton.

To show a checkmark next to a popup menu item, consider using CheckedPopupMenuItem.

Typically the child of a PopupMenuItem is a Text widget. More elaborate menus with icons can use a ListTile. By default, a PopupMenuItem is kMinInteractiveDimension pixels high. If you use a widget with a different height, it must be specified in the height property.

Here, a Text widget is used with a popup menu item. The Menu type is an enum, not shown here.

const PopupMenuItem<Menu>(
  value: Menu.itemOne,
  child: Text('Item 1'),
)

See the example at PopupMenuButton for how this example could be used in a complete menu, and see the example at CheckedPopupMenuItem for one way to keep the text of PopupMenuItems that use Text widgets in their child slot aligned with the text of CheckedPopupMenuItems or of PopupMenuItem that use a ListTile in their child slot.
