A simple overview of Performance Optimization Techniques for Large React Native Apps. Learn what it means, when it helps, and what to check first.
1. Use FlashList instead of FlatList
Shopify's FlashList recycles views much more efficiently than the standard FlatList, crucial for long lists of data.
2. Memoization
Prevent unnecessary re-renders of child components by using React.memo and useCallback.
jsx
const MyItem = React.memo(({ title }) => {
return <Text>{title}</Text>;
});
