I'm facing a problem with Android 12 overscroll configuration and nested scroll. I'm using nestedScroll to detect whether a child ScrollState reaches the top, so I can forward the deltas to the parent's DraggableState (see video). However, the android 12 stretch overscroll effect seems to use the available deltas (which is expected to perform the animation), but it also consumes them, and it causes my nestedScroll onPreScroll available parameter to be very close to zero.
How can I tell the overscroll effect to not the deltas?

(the first clip is how it looks like without the overscroll effect)

I think the problem would be solved if only the overscrollEffect was exposed as a parameter in both scroll Modifier and LazyList (like flingBehavior)

It’s hard to tell without the code but I don’t think this has anything to do with overscroll effect. ModalBottomSheetLayout has similar effect and it works well on Android 12+.

Your NestedScrollConnection should be the same as this.

Thanks, I'm gonna check it out

Yep, it works - my onPostScroll was faulty 🙂

I didn't thank you yet - I was pretty sure it was a overscroll effect problem - it would have taken ages to figure out!
