PopupMenuItemState<T, W extends BottomPopupMenuItem<T>> class

The State for BottomPopupMenuItem subclasses.

By default this implements the basic styling and layout of Material Design popup menu items.

The buildChild method can be overridden to adjust exactly what gets placed in the menu. By default it returns BottomPopupMenuItem.child.

The handleTap method can be overridden to adjust exactly what happens when the item is tapped. By default, it uses Navigator.pop to return the BottomPopupMenuItem.value from the menu route.

This class takes two type arguments. The second, W, is the exact type of the Widget that is using this State. It must be a subclass of BottomPopupMenuItem. The first, T, must match the type argument of that widget class, and is the type of values returned from this menu.
