EmptyTextSelectionControls class

Text selection controls that do not show any toolbars or handles.

This is a placeholder, suitable for temporary use during development, but not practical for production. For example, it provides no way for the user to interact with selections: no context menus on desktop, no toolbars or drag handles on mobile, etc. For production, consider using MaterialTextSelectionControls or creating a custom subclass of TextSelectionControls.

The emptyTextSelectionControls global variable has a suitable instance of this class.
