Have you made sure that it wasn't a React Native bug?

yes

Is the bug specific to iOS or Android? Or can it be reproduced on both platforms?

iOS & Android - all versions

Is the bug reproductible in a production environment (not a debug one)?

yes

Environment

Environment: React: 16.12.0 React native: 0.61.5 react-native-snap-carousel: 3.8.4

Target Platform: Android (6.0) iOS (10.3)

Expected Behavior

The snap carousel should continue in the direction the user scrolls, then snap to an item in that direction once the carousel finishes scrolling (or close to finishing, e.g slowing down)

Actual Behavior

The snap carousel scrolls in the direction the user slides although, once it slows down, it starts sliding and snapping in the opposite direction.

Here is a screen recording showing the issue: https://imgur.com/gallery/dzpcrM8

Reproducible Demo

Unable to post a demo as this is a client project. Hopefully somone knows how to fix this issue by seeing the movie and description above.

Steps to Reproduce

<Carousel
    enableMomentum
    triggerRenderingHack
    ref={oddsRoll}
    data={ODDS}  // array of numbers [10, 11, 12, 13, ...]
    itemWidth={50}
    itemHeight={50}
    inactiveSlideOpacity={0.15}
    inactiveSlideScale={0.9}
    renderItem={renderCarouselItem} // a simple PureComponent with Text inside a View
    sliderWidth={sliderWidth} // this changes based on a few things.  Assume it's screen width
    onSnapToItem={index => setIndex(index)}
/>

Load a array of numbers into Carousel
Scroll left or right

Thanks for your help in advance. Hopefully it's something i'm doing wrong and not an issue with react-native-snap-carousel itself.

@bd-arc nice work! The latest version 4.0.0-beta.5 seems work fine without going back when scrolling cards horizontally!

Sorry, please allow me to advertise for my open source library! ~ I think this library react-native-reanimated-carousel will solve your problem. It is a high performance and very simple component, complete with React-Native reanimated 2
