CustomSemanticsAction class Null safety
An identifier of a custom semantics action.
Custom semantics actions can be provided to make complex user interactions more accessible. For instance, if an application has a drag-and-drop list that requires the user to press and hold an item to move it, users interacting with the application using a hardware switch may have difficulty. This can be made accessible by creating custom actions and pairing them with handlers that move a list item up or down in the list.
In Android, these actions are presented in the local context menu. In iOS, these are presented in the radial context menu.
Localization and text direction do not automatically apply to the provided label or hint.
Instances of this class should either be instantiated with const or new instances cached in static fields.
