描述

Hi guys,

I've searched around a lot and haven't found any information about this, but even the simplest of tests with the carousel I find are very jerky.

When swiping between items in the carousel, I notice that as soon as I release my finger, the speed of the snap changes. This means when I quickly flick to the next item, it instantly slows the snap speed so it looks like the swipe "hit a wall."

I'm tested this using Expo on an iPhone 7.

I've compared this to the native ScrollView with pagingEnabled or even snapToInterval and that has a much smoother effect.

Is this purely because the "snapping" action can't work out how much force a user swiped with? Or am I completely missing something?

I can probably put together an Expo snack to demonstrate the issue if need be.

研究方向
Investigate the carousel's snapping animation logic in the source code (e.g., Carousel.js). Compare the behavior with native ScrollView's pagingEnabled. Review the 30 comments for any proposed fixes or insights. Consider creating an Expo snack to reproduce the issue for precise debugging.
