If it helps anyone, the documentation here is relevant: https://facebook.github.io/react-native/docs/flatlist.html

In order to constrain memory and enable smooth scrolling, content is rendered asynchronously offscreen. This means it's possible to scroll faster than the fill rate and momentarily see blank content. This is a tradeoff that can be adjusted to suit the needs of each application, and we are working on improving it behind the scenes.

So FlatList is already partially performing most of the functionality you require. In particular, try using the removeClippedSubviews prop - this may solve some of your performance issues!

Tweaking the viewabilityConfig prop may also help.
