react-native-snap-carousel: Scrolling on android appears to get stuck between views unless moved slowly

Is this a bug report, a feature request, or a question?

Bug Report

Have you followed the required steps before opening a bug report?

(Check the step you’ve followed - put an x character between the square brackets ([]).)

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?

Android

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

I have confirmed this by building the android app with NODE_ENV=production in my env file, yes.

Environment

Environment: React: 17.0.1 React native: 0.64.2 react-native-snap-carousel: 3.9.1

Target Platform: Android (12.5.3)

Expected Behavior

Swiping between views on Android should snap to the next view when released.

Actual Behavior

If I swipe with some (pretty normal) momentum, the carousel will get stuck between 2 pages, and not call the onSnapToItem method. If I swipe slowly and release about halfway, it perfectly snaps perfectly to the next page. I am aware of the performance issues on android and have tried many props/settings and fixes found in various places on the internet and in the issues here, apologies if I’ve missed something very common.

Reproducible Demo

(Paste the link to a Snack example in which the issue can be reproduced. Please follow the guidelines for providing a Minimal, Complete, and Verifiable example.)

Steps to Reproduce

These are the current settings after all my efforts.

          <Carousel
            scrollEnabled={calendarState === CalendarState.Open}
            firstItem={prevMonths}
            data={monthData}
            sliderWidth={calendarWidth}
            itemWidth={calendarWidth}
            inactiveSlideOpacity={0.5}
            inactiveSlideScale={0.8}
            inactiveSlideShift={0}
            removeClippedSubviews={false}
            lockScrollWhileSnapping={isAndroid}
            enableMomentum={false}
            disableIntervalMomentum
            enableSnap
            onSnapToItem={onMonthChanged}
            renderItem={renderItem}
          />

I am using the carousel to create a calendar, each page is a “month” containing rows of weeks, containing 7 days, there is a lot of elements here when you consider we have potentially 42 “days” per month/page and in my case, up to 7 months at a time…

Hi, as it said in their guide, you should put those props

...
enableMomentum={false}
decelerationRate={0.9}
...

Hope it helps. This is how I fix this problem

I had the same issue I solved by adding pagingEnabled and it worked well on android and ios

yes, react native 0.63.4 is ok,but 0.66.3 is broken it is react native version problem

This works for me. Thank you

I think it’s an issue caused by the RN version. I downgraded the version from 0.64.1 to 0.63.4 and it didn’t happen anymore.

It is recommended to use the react-native-reanimated-carousel library. The current library seems to be no longer maintained.

Not sure if this helps anyone, but I did an edit to the Carousel.js, line 567 which made it at least useable. I removed the centerOffset.

if (this._positions[lastIndex] && center> this._positions[lastIndex].end) {
