Is there any way of reading the key of the item currently being dragged inside the render item function?
I'm using this to apply styles based on if the item is being dragged or not.

I managed to do this by creating my own context wrapping Sortable.Grid with a SharedValue of the active item key. I then set this value in onDragStart/onDragEnd.

This value can be read inside a component rendered in renderItem.

const RenderItem = (item) => {
 const activeItem = useContext(ActiveItemContext).activeItem; <-- shared value
 const animatedStyle = useAnimatedStyle(() => {
 const isActive = activeItem.value === item.id;
 // return animated styles based on item being dragged or not
 });
}

I think this could be more easily be provided by this library.
