🚀 Flatlist vs Scrollview in React Native 🚀
ScrollView :
1. Purpose:
ScrollView is designed to render all child components at once, making it ideal for relatively small lists of items or when the content size is manageable.
2. Rendering:
• Renders all elements in the list, even if they are off-screen.
• Can cause performance issues with large datasets because all items are kept in memory.
3. Use Case:
• Suitable for static or limited dynamic content where the number of items is small (e.g., a small form or a gallery with few images).
• Nested content with various layouts.
4. Key Features:
• Allows for vertical and horizontal scrolling.
• Can be nested inside other ScrollViews, but overuse can lead to poor performance.
5. Performance:
• Not memory-efficient for large datasets due to rendering all components at once.
FlatList:
1. Purpose:
FlatList is optimized for handling large datasets by rendering items lazily, only loading the visible ones and a few items off-screen.
2. Rendering:
• Renders only the items visible on the screen (plus some buffer) using a virtualized list mechanism.
• Reuses components as the user scrolls, which improves memory usage.
3. Use Case:
• Ideal for dynamic or large datasets where performance is crucial (e.g., a feed, list of products, or chat application).
• Supports infinite scrolling and item separators.
4. Key Features:
• Supports lazy loading (via onEndReached).
• Allows for highly customizable layouts via renderItem and supports advanced features like sticky headers.
5. Performance:
• Highly efficient for large datasets due to its virtualized rendering approach.
