How to get y value of sheet on drag

[bennettl]

Is it possible to invoke a function as the user drags the modal to get the y position of the sheet? Readme mentions using refs, but unclear on how to go about getting the latest values. I tried the following

const ref = useRef();

useEffect(() => {
// Use the latest y value
},[ref.current.y] ]

<Sheet ref={ref}> ... </Sheet>

The y value is a MotionValue and its value is updated outside of React so you need to subscribe to the value changes via y.onChange.
