MongolPopupMenuItem<T> class

An item in a Mongol material design popup menu.

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

Typically the child of a MongolPopupMenuItem is a MongolText widget. More elaborate menus with icons can use a MongolListTile. By default, a MongolPopupMenuItem is kMinInteractiveDimension pixels wide. If you use a widget with a different width, it must be specified in the width property.

{@tool snippet}

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

const MongolPopupMenuItem<WhyFarther>(
  value: WhyFarther.harder,
  child: MongolText('Working a lot harder'),
)

{@end-tool}

See the example at MongolPopupMenuButton for how this example could be used in a complete menu.
