FlatList
renders items lazily, when they are about to appear, and removes items that scroll way off screen to save memory and processing time.- The
FlatList
component displays a scrolling list of changing, but similarly structured, data. FlatList
works well for long lists of data, where the number of items might change over time. Unlike the more genericScrollView
, theFlatList
only renders elements that are currently showing on the screen, not all the elements at once.
