ContextMenuItem<T> class abstract base

Represents a selectable item in a context menu.

The ContextMenuItem class is used to define individual items that can be displayed within a context menu. It extends the ContextMenuEntry class, providing additional functionality for handling item selection, submenus, and associated values.

A ContextMenuItem can have an associated value that can be returned when the item is selected. It can also contain a list of items to represent submenus, enabling a hierarchical structure within the context menu.

When a ContextMenuItem is selected, it triggers the handleItemSelection method, which determines whether the item has subitems. If it does, it toggles the visibility of the submenu associated with the item. If not, it pops the current context menu and returns the associated value.

Parameters:

• value - The value associated with the context menu item.
• items - The list of subitems associated with the context menu item.
• onSelected - The callback that is triggered when the context menu item is selected.
