Infinite Scroll
Infinite Scroll
Infinite scroll automatically loads more content as the user scrolls near the bottom of a list, creating a seamless browsing experience commonly seen in social media and e-commerce apps.
Setting Up the FlatList

item.id.toString()}
renderItem={({ item }) =>
Implementing the Load More Function
javascript
const [loadingMore, setLoadingMore] = useState(false);
async function loadMorePosts() {
if (loadingMore || !hasMore) return;
setLoadingMore(true);
const response = await axios.get('/posts', { params: { page: nextPage } });
setItems((prev) => [...prev, ...response.data.items]);
setNextPage((prev) => prev + 1);
setHasMore(response.data.hasMore);
setLoadingMore(false);
}

Combining with Pull-to-Refresh
Infinite scroll is often combined with pull-to-refresh, allowing users to reload from the beginning of the list while still being able to scroll down for older content.
javascript
Performance Considerations
Combine infinite scroll with FlatList’s built-in performance props, such as windowSize and removeClippedSubviews, to maintain smooth scrolling performance even as the list grows very large.
Conclusion
Infinite scroll, implemented correctly with proper loading state management and FlatList optimization, provides a smooth, engaging browsing experience for content-heavy React Native applications.
