ChipEventController typedef

ChipEventController = WidgetEventController

Manages a set of ChipEvents and notifies listeners of changes.

Used by widgets that expose their internal event for the sake of extensions that add support for additional events.

The controller's value is its current set of events. Listeners are notified whenever the value changes. The value should only be changed with update; it should not be modified directly.

Implementation

typedef ChipEventController = WidgetEventController;
