FlatList — Rendering Lists of Data | React Native Beginner Tutorial
Lists are everywhere. FlatList is how you build them right.
Your contacts. Your messages. Your shopping cart. Your feed. Apps are mostly lists. If you cannot build a list, you cannot build an app. FlatList is React Native's dedicated list component — and it is smarter than using a simple map.
What you will build:
A stylised list of 10 items — your choice: favorite movies, goals for the year, books to read. Each item beautifully formatted. Scrollable. Performant.
What you will learn:
FlatList vs map (why FlatList wins for long lists)
keyExtractor — why every item needs a unique ID
Item separators — lines between list items
Handling empty lists (what to show when there is nothing)
Why FlatList matters:
Map works for 3 items. For 300? Your app will stutter. FlatList is built for performance — it only renders what is on screen.
Your task after this video:
Render a list of 10 items. Add custom styling — different colors for odd and even items. Add a separator line. Take a screenshot. Share it.
Bonus challenge:
Make each item tappable. When tapped, show an alert with the item name.
