When building a mobile app, one codebase for iOS and Android — big advantage. Flutter and React Native — most popular. Flutter (Google), React Native (Meta).
React Native
Easy if you know JavaScript. Large community. Hot reload. Drawbacks: performance sometimes lower. Native code may be needed.
Flutter
High performance. Beautiful UI. Need to learn Dart. Larger app size. Google support.
Which to choose?
Know JavaScript → React Native. Starting fresh → Flutter. Performance matters → Flutter. Web + Mobile → React Native.
Conclusion
Both are good choices. Choose based on your goal!
