Description

Hello Thanks for this package, its very useful for my project.

When I am using onSnapToItem={index => setActiveSlide(index)} it updates the state and update active dot but on next slide it resets the Carousel items and starts the play from first item again.

If I remove onSnapToItem autoplay works fine.
I think something wrong with updating state with my code?
Could someone pls help looking into this ? Thanks

Here is my code:

<View style={[styles.homePriorityNotifMainView]}>
      <Carousel
        // ref={c => this._slider1Ref = c}
        loop
        enableSnap
        autoplay={true}
        layout={'default'}
        autoplayInterval={3000}
        data={notifications}
        sliderWidth={deviceWidth}
        itemWidth={deviceWidth}
        renderItem={_renderItemCarousel}
        activeAnimationType={'spring'}
        removeClippedSubviews={false}
        onSnapToItem={index => setActiveSlide(index)}
      />
      <Pagination
        dotsLength={notifications.length}
        activeDotIndex={activeSlide}
        containerStyle={{
          //  width: 200
        }}
        dotStyle={{
          width: 10,
          height: 10,
          borderRadius: 5,
          //    marginHorizontal: 8,
          backgroundColor: 'red'
        }}
        inactiveDotStyle={{
          backgroundColor: 'yellow'
        }}
        inactiveDotOpacity={0.4}
        inactiveDotScale={0.6}
      />
    </View>

Research direction

Start with the Carousel behavior for autoplay, loop, and onSnapToItem, using the provided example with Pagination as the reproduction case. Check how updating activeSlide affects the carousel's current item and autoplay state. Done means autoplay advances beyond the first item while the pagination remains synchronized.
