Description

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

This is a question.

When I am using autoplay={true}, the memory usage keeps growing and it is making jumps.

When I am using autoplay={false}, the memory usage is stable (above second part) but every time I slide an item, the memory increases as following. I am using PureComponent for each slide. Anyone face this problem before? When I left the app opened for a few hours, it gets to 1 - 2GB memory usage.

Research direction

Start by reproducing the reported memory growth with react-native-snap-carousel 3.8.4 on the stated React Native and iOS Simulator versions, comparing autoplay={true} and autoplay={false}. Use the memory profiler while sliding items and determine whether the issue is in the carousel or the slide components; done means identifying a reproducible cause and documenting a verified resolution.
