# mouseWheelEvent constant

EventStreamProvider<WheelEvent> const mouseWheelEvent = const _CustomEventStreamProvider<WheelEvent>(Element._determineMouseWheelEventType)

See EventStreamProvider for usage information.

    static const EventStreamProvider<WheelEvent> mouseWheelEvent =
        const _CustomEventStreamProvider<WheelEvent>(
            Element._determineMouseWheelEventType)
