PopupMenuEntry<T> class
abstract
A base class for entries in a material design popup menu.
The popup menu widget uses this interface to interact with the menu items. To show a popup menu, use the showMenu function. To create a button that shows a popup menu, consider using PopupMenuButton.
The type T is the type of the value(s) the entry represents. All the
entries in a given menu must represent values with consistent types.
A PopupMenuEntry may represent multiple values, for example a row with several icons, or a single entry, for example a menu item with an icon (see PopupMenuItem), or no value at all (for example, PopupMenuDivider).

- PopupMenuItem, a popup menu entry for a single value.

- CheckedPopupMenuItem, a popup menu item with a checkmark.
- showMenu, a method to dynamically show a popup menu at a given location.
