how to get index of the item, when pagingEnabled

I want to use pagingEnabled option in Carousel, since it is working as expected and is not giving any performance issue in android.
Without using that prop, their is slight delay in manually scrolling the items placed horizontally , but on iOS it working fine.

This is what the initial implementation was.

<Carousel
        onSnapToItem={(slideIndex: number) => {
         setSlideIndex(slideIndex);
        }}
       data={data}
       renderItem={renderSliderItem}
       sliderWidth={carouselWidth}
       itemWidth={carouselWidth}
       loop={true}
       slideStyle={{ width: carouselWidth }}
       autoplay={autoPlay}
       autoplayDelay={scrollInterval}
       autoplayInterval={scrollInterval}
       useScrollView
       enableSnap={true}
       shouldOptimizeUpdates={true}
       loopClonesPerSide={5}
       enableMomentum={true}
       decelerationRate={0.9}
       activeSlideAlignment="center"
       removeClippedSubviews={true}
       inactiveSlideScale={1}
       inactiveSlideOpacity={1}
       inactiveSlideShift={1}
       lockScrollWhileSnapping={true}
       />

But it not working. so added changed it to following

<Carousel
        // onSnapToItem={(slideIndex: number) => {
        //   setSlideIndex(slideIndex);
        // }}
        data={data}
        renderItem={renderSliderItem}
        sliderWidth={carouselWidth}
        itemWidth={carouselWidth}
        loop={true}
        slideStyle={{ width: carouselWidth }}
        autoplay={autoPlay}
        autoplayDelay={scrollInterval}
        autoplayInterval={scrollInterval}
        useScrollView
        enableSnap={true}
        shouldOptimizeUpdates={true}
        loopClonesPerSide={5}
        enableMomentum={true}
        decelerationRate={0.9}
        activeSlideAlignment="center"
        removeClippedSubviews={true}
        inactiveSlideScale={1}
        inactiveSlideOpacity={1}
        inactiveSlideShift={1}
        activeSlideOffset={0.5}
        lockScrollWhileSnapping={true}
        pagingEnabled
        onMomentumScrollEnd={onScrollEnd}
        />

   But onScrollEnd function is not giving correct index. 

      
let onScrollEnd = (e) => {
    let pageNumber = Math.min(
      Math.max(Math.floor(e?.nativeEvent?.contentOffset?.y / winWidth + 0.5) + 1, 0),
      data?.length
    );
    console.log(pageNumber);
   
  };

Please suggest. Stuck here.

Start by reviewing the Carousel configuration using pagingEnabled and onMomentumScrollEnd, then inspect the onScrollEnd calculation based on nativeEvent.contentOffset.y and winWidth. Compare the reported index with the carousel's actual item position and determine what behavior is expected. Done means the callback consistently reports the correct item index on Android.
