Flutter and React Native promise one codebase. Production says otherwise. After 12+ years building mobile apps across Android, Flutter, and React Native — here's the honest breakdown: 🔷 Flutter ✅ Great for MVPs, UI-heavy apps, and fast launches ❌ Plugin dependency becomes a real problem at scale 🔶 React Native ✅ Strong fit for JS teams and rapid iterations ❌ The JS bridge becomes a bottleneck as complexity grows 🔹 Native (Android / iOS) ✅ Best for performance, stability, and complex SDK integrations ❌ Slower to start, higher upfront cost The hidden truth no one talks about: As your app scales, that "single codebase" typically splits into ~70% shared and ~30% platform-specific — and that 30% is usually the most critical part. The best teams don't pick one and stick to it rigidly. They start cross-platform for speed, then move performance-critical modules to native. Architecture flexibility from day one is the real competitive advantage. 📖 Full breakdown in my latest Medium article — link in comments. #MobileDevelopment #Flutter #ReactNative #Android #CrossPlatform #SoftwareEngineering

Good overview, but worth adding some data: Flutter and React Native are almost neck-to-neck in developer usage (~9.2% vs 9.1% in StackOverflow surveys), while in enterprise RN still slightly leads (~42% vs ~38%). https://www.nomtek.com/blog/flutter-vs-react-native, So the “what works in production” answer is less about tech and more about team + use case.
Flutter in production is very easy. Dependencies can be a problem if you don’t choose them right and don’t know how to handle abstractions. But don’t all dependencies do that on all platforms?
Fully crud application does well with abstraction frameworks. Native if any part of the app requires platform access. Otherwise the 30% will cripple productivity of an app.
What about the KMP?
