Performance Optimization Techniques for Large React Native Apps

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.

const MyItem = React.memo(({ title }) => {
  return <Text>{title}</Text>;
});
