What is better Flutter or React Native?
Both Flutter and React Native are good, but the better choice depends on what you care about: performance, speed, job demand, or ease of learning. I’ll give you a clear, teacher-style comparison so you can decide without confusion.
🚀 Overview
Flutter → made by Google
React Native → made by Meta
Both are used for cross-platform app development (Android + iOS).
⚡ Performance
✅ Winner: Flutter
Flutter uses its own rendering engine
Faster UI
Smoother animations
React Native depends on native components → slightly slower in heavy apps.
👉 If performance matters → choose Flutter.
🎨 UI Design & Customization
✅ Winner: Flutter
Ready-made UI widgets
Same design on Android & iOS
Easier to make beautiful apps
React Native uses native UI → sometimes different look on devices.
👉 If you want modern UI → Flutter is better.
💻 Programming Language
Flutter → Dart
React Native → JavaScript
✅ Winner: React Native (for beginners)
Because JavaScript is more popular than Dart.
👉 If you know JavaScript → React Native is easier.
📈 Job Demand (Important)
Depends on location, but generally:
React Native → more jobs
Flutter → growing fast
Reason:
React Native uses JavaScript → used everywhere.
👉 If job is priority → React Native slightly better
👉 If future growth → Flutter strong choice
🔧 5. Development Speed
Both are fast, but:
Flutter → faster UI build
React Native → faster if you know JS
Tie, but many developers prefer Flutter now.
| Situation | Better Choice |
|---|---|
| Beginner with no coding | Flutter |
| Know JavaScript | React Native |
| Best performance | Flutter |
| More job options | React Native |
| Future proof | Flutter |
| Easy UI design | Flutter |

Save file to see changes.
Step 6 – Add UI Components
React Native uses components.
Examples:
View
Text
Button
Image
ScrollView
You can design screens using components.
Step 7 – Build App File
For Android:
