Has anyone managed to successfully use LazyListState.animateScrollToItem to scroll forward such that the item’s bottom aligns to the bottom of the list? I was hoping animateScrollToItem(index+1, -viewportHeight) would do the trick, but unfortunately it does a weird overscroll and then scroll back to position. Any other idea I’ve had involves knowing the height of the item.

My guess that spring animation spec causing this.

Does it work to use BringIntoViewRequester https://cs.android.com/androidx/platform/frameworks/support/+/androidx-main:compose/foundation/foundation/src/commonMain/kotlin/androidx/compose/foundation/relocation/BringIntoViewRequester.kt;l=70?q=BringIntoViewRequester to try to bring it into the view instead? It might then bring it just enough so that it's on the screen, so if it was further down, it might appear at the bottom of the list?
But this might not work for lazy lists tbh

It can’t work. The item lambda passed to e.g. LazyListScope.items is never even executed for non-visible items, so the BringIntoViewRequester isn’t attached to any node.

and you can’t use it on the LazyList itself because you don’t know the Rect to pass to BringIntoViewRequester.bringIntoView (because, again, you don’t know the item heights)
