This PR adds the
windowSize
prop to improve the performance of nested FlatList components. This prop allows developers to control how many items are rendered around the current scroll position, helping optimize memory usage and performance for large lists.The
windowSize
defaults to 21 as per React Native’s default behavior, but it can now be customized by the user based on the size of their list and performance needs. This prop significantly improves scrolling performance, particularly in long or image-heavy masonry layouts by reducing the number of items in memory.
