Add a way to read current index about react-native-reanimated-bottom-sheet

I'd be happy with just onChange event that fires when the bottom sheet moves from one snap point to the other.

Hello,
I find it a little bit tricky because this change is not a discrete change.
You know, it's quite difficult to asses when we actually change the index. IS it on start snapping? Or ending? Or when we start assuming that this interaction leads to the index's change?
I think you need to determine it on yourself using callbackNode. It has information about position and then you may get the information you want in a way you want. 😄

I get why this is difficult because there are in-between states, but I wonder if something like onSnapLeave and onSnapComplete would be appropriate... so when dragging away from a snap you get the leave event and when it settles at a snap point, you get the completion event...

I know that may still not be trivial but it's a thought.
