FlatList

FlatList is a high-performance React Native component for rendering large, scrollable lists of data efficiently. It renders only the items currently visible on screen, using a 'virtualized' approach to optimize memory usage and scrolling performance. It supports features like pull-to-refresh, infinite scrolling, and customizable item separators.

Also known as: Flat List, React Native FlatList, RN FlatList, Flatlist, FlatList Component

Why learn FlatList?

Developers should use FlatList when building mobile apps with React Native that require displaying long lists or grids, such as social media feeds, product catalogs, or chat histories. It's essential for performance-critical applications because it minimizes rendering overhead and provides smooth scrolling, unlike basic ScrollView which renders all items at once.
