To someone reading the code later, however, it won’t be obvious why the dependency on itemsFromServer is needed. Our code now works.Īs we just saw, the dependency on itemsFromServer is critical for our code to work. Since we added itemsFromServer to the list of the dependencies the hook will now re-run and correctly attach the scroll listener to the div on the page. Its built-in optimizations, such as item recycling and virtualization, make it a go-to choice for developers working with extensive data sets in mobile applications.īy harnessing the capabilities of FlatList and understanding its key features and optimizations, React Native developers can create smooth and responsive user experiences even when dealing with sizable amounts of data in their applications.UseEffect ( ( ) =>, ) ConclusionįlatList in React Native offers a powerful and efficient way to render large lists of data while maintaining optimal performance. Customizing FlatList based on specific app requirements can enhance the user experience and make the app more efficient and engaging. These snippets showcase various ways to leverage FlatList's capabilities, including horizontal lists, grid layouts, item separators, handling end-reached events, controlling scrolling behavior, and dynamically adjusting item heights based on content. SetScrollEnabled(false) // Disable scrollingĪdjusting the height of list items dynamically based on content. (Ĭontrolling the scroll behavior of FlatList using the scrollEnabled prop. Implementing the onEndReached prop to load more data when reaching the end of the list. (Īdding a separator between items in the list using the ItemSeparatorComponent prop ( To display a grid layout with multiple columns, use the numColumns prop. To render a horizontal list using FlatList, set the horizontal prop to true.
