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 generic
FlatList only renders elements that are currently showing on the screen, not all the elements at once.
FlatList component requires two props:
data is the source of information for the list.
renderItem takes one item from the source and returns a formatted component to render.
This example creates a basic
FlatList of hardcoded data. Each item in the
data props is rendered as a
Text component. The
FlatListBasics component then renders the
FlatList and all
If you want to render a set of data broken into logical sections, maybe with section headers, similar to
UITableViews on iOS, then a SectionList is the way to go.
One of the most common uses for a list view is displaying data that you fetch from a server. To do that, you will need to learn about networking in React Native.
