🚀 Flutter Tip: Optimize Your ListView Performance with ListView.builder
When displaying a long list of items in Flutter, using a simple ListView
can lead to performance issues because all items are built at once. Instead, use ListView.builder
, which builds only the visible items, improving performance significantly.
✨ Example:
ListView.builder(
itemCount: 1000, // Large number of items
itemBuilder: (context, index) {
return ListTile(
title: Text('Item \$index'),
);
},
)
🔥 Why use ListView.builder
?
✅ Efficient Rendering: Only builds items when they are visible.
✅ Reduced Memory Usage: Keeps the widget tree light and responsive.
✅ Smooth Scrolling: Prevents lag and stutter in long lists.
Using ListView.builder
ensures a smoother user experience, especially when working with dynamic lists. Try it in your project today! 🚀
