Yes, there has been bug, you need to change the source code, when you operate fast, it will appear, you can prompt the user on the interface, please slow down ：D

The issue lies in handleOnAnimate function being a dependency for animateToPosition in @gorhom/bottom-sheet/src/components/bottomSheet/BottomSheet.tsx

I didn't manage to find the reason how a dependency change retriggers animateToPosition (which retriggers something else and so on). Will look into that if I have time. But please do join me in this bugfixing.

UPDATE:
I found the reason why that is happening. handleOnAnimate recreates, which recreates animateToPosition, which recreates handleSnapToIndex, which is calling useEffect on this line . Which is basically why this bug happens. Will think of a fix for that.

UPDATE 1:
Here is the fix #2073
