When working with FlashList, it can be difficult to efficiently handle huge datasets in React Native. Components that re-render needlessly when scrolling are a problem that many developers encounter. Performance bottlenecks may result from this, giving the program a sluggish feel. Developers can significantly increase rendering efficiency by utilizing built-in FlashList attributes, optimizing state management, and putting solutions like memoization into practice. These methods not only improve scrolling speed but also guarantee a smooth user experience, especially in applications that need to show hundreds of items, such as food delivery or e-commerce platforms.
