Cmn
interface RotaryInputModifierNode : DelegatableNode
Implement this interface to create a Modifier.Node that can intercept rotary scroll events.
The event is routed to the focused item. Before reaching the focused item, onPreRotaryScrollEvent is called for parents of the focused item. If the parents don't consume the event, onPreRotaryScrollEvent is called for the focused item. If the event is still not consumed, onRotaryScrollEvent is called on the focused item's parents.

Public functions
onPreRotaryScrollEvent
fun onPreRotaryScrollEvent(event: RotaryScrollEvent): Boolean
This function is called when a RotaryScrollEvent is received by this node during the downward pass. It gives ancestors of a focused component the chance to intercept an event. Return true to stop propagation of this event. If you return false, the event will be sent to this RotaryInputModifierNode's child. If none of the children consume the event, it will be sent back up to the root using the onRotaryScrollEvent function.
onRotaryScrollEvent
fun onRotaryScrollEvent(event: RotaryScrollEvent): Boolean
This function is called when a RotaryScrollEvent is received by this node during the upward pass. While implementing this callback, return true to stop propagation of this event. If you return false, the key event will be sent to this RotaryInputModifierNode's parent.
