How do you create a simple list in Flutter?

Updated Apr 28, 2026

Short answer

By using the ListView widget, specifically ListView.builder for dynamic or large lists.

Deep explanation

ListView displays children in a scrollable column or row. For small lists, children can be passed directly. For large or infinite lists, ListView.builder creates items lazily only when they are about to scroll into view, which is highly memory efficient.

Real-world example

Displaying a scrolling feed of user posts or a long list of contacts in an address book app.

Common mistakes

  • Using standard `ListView(children: [...])` for thousands of items, which renders them all at once and crashes the app (Out of Memory).
