The type of menu item.


Values of this type are strings. Possible values are:

A context menu item that just displays a label.

A context menu item that represents a binary state. It displays a checkmark next to the label. Clicking the item toggles the checkmark. The contextMenus.onClicked listener will be passed two extra properties: "checked", indicating whether the item is checked now, and "wasChecked", indicating whether the item was checked before the click event.


A context menu item that represents one of a group of choices. Just like a checkbox, this also displays a checkmark next to the label, and its contextMenus.onClicked listener is passed "checked" and "wasChecked". However, if you create more than one radio item, then the items function as a group of radio items: only one item in the group can be checked, and clicking an item makes it the checked item.

A line separating a group of items.
