PopupMenuEntry<T> class Null safety

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).
