FlashList offers significant performance improvements over FlatList for complex React Native lists through cell recycling instead of virtualization. In a real-world project with nested lists and animations, switching to FlashList and optimizing properties like estimatedItemSize, getItemType, and overrideItemLayout resulted in 54% FPS improvement (36.9 to 56.9), 82% CPU reduction, and eliminated out-of-memory crashes on low-end Android devices. The article provides practical implementation tips including data reorganization and proper configuration strategies.
