How can I improve the performance of FlatList in React Native?

To improve FlatList performance, consider using the following techniques: 1. Use getItemLayout for fixed-height items. 2. Implement shouldComponentUpdate to prevent unnecessary re-renders. 3. Use initialNumToRender to control the number of items rendered initially.

What about using windowing and virtualization?

Great question! FlatList already implements virtualization, which means it only renders items that are currently visible on the screen. You can adjust the windowSize prop to control how many items are rendered outside the viewport.

Are there any specific props I should avoid?

Yes, avoid using extraData unless necessary, as it can lead to performance issues by causing re-renders. Also, be cautious with keyExtractor if it generates keys dynamically.

Can you suggest some libraries that help with performance?

Sure! Libraries like react-native-reanimated and react-native-gesture-handler can help improve performance by optimizing animations and gestures.
