snapToItem does not move the slider to a specific position when list length is more than 15 items.

There is a slider that contains more than 200 images there is a circular slider from which we slide that image slider. so we need to call the snapToItem method to move the carousel in a specific position. but snapToItem does not move the carousel to a specific position.

if the slider has only 10 or 15 images then it works perfectly but if we have more than 15 images snapToItem method doesn’t work properly.

@yorickshan have you provided getItemLayout props.

<Carousel
    ref={carouselRef}
    data={data}
    renderItem={renderCarouselItem}
    sliderWidth={width}
    itemWidth={ITEM_WIDTH}
    getItemLayout={getCarouselItemLayout}
  />

const getCarouselItemLayout = (_: any, index: number) => ({
    length: ITEM_WIDTH,
    offset: ITEM_WIDTH * index,
    index,
  });

carouselRef.current.snapToItem(index);
