Cross-Platform Mobile: Flutter vs React Native

Building native apps is expensive (Swift + Kotlin). Cross-platform is the answer.

React Native (Meta)

Uses JavaScript/TypeScript. It renders native UI components.

• Pros: Share code with web (React), massive JS ecosystem, native look and feel.
• Cons: Performance can lag (JS Bridge), upgrades are painful.

Flutter (Google)

Uses Dart. Renders its own UI (like a game engine).

• Pros: Consistent UI on every pixel (looks the same on iOS/Android), amazing performance (compiled to native), great developer tools.
• Cons: Dart (another language to learn), not “native” UI components (mocked).

Conclusion

• If you are a web developer: React Native is easier.
• If you want the best performance and UI consistency: Flutter.
