Flutter vs React Native
Google's Dart framework vs Meta's JavaScript framework. Both promise one codebase for iOS and Android. Both deliver, with caveats.
React Native
React Native wins on ecosystem and hiring. JavaScript developers are everywhere. The React mental model transfers directly. Expo has closed the DX gap. Flutter is technically impressive but Dart is a harder sell for most teams.
Language Matters
Flutter uses Dart. It's a fine language, but your team probably doesn't know it. Finding Dart developers is harder than finding JavaScript developers. Training costs are real.
React Native uses JavaScript/TypeScript. If your team knows React (and they probably do), they can build mobile apps. The knowledge transfer is direct.
Performance
Flutter compiles to native ARM code and renders with its own engine (Skia/Impeller). No bridge, no JavaScript thread. Animations are smooth, performance is consistent.
React Native's new architecture (Fabric + TurboModules) eliminated the bridge. Performance is much better than old React Native. But Flutter still has an edge for animation-heavy apps.
The Ecosystem
React Native has npm. The entire JavaScript ecosystem is available. Need a library? It probably exists.
Flutter's pub.dev ecosystem is smaller but curated. Firebase integration is excellent (Google to Google). But for niche requirements, you'll find more options in npm.
Quick Comparison
| Factor | Flutter | React Native |
|---|---|---|
| Language | Dart | JavaScript/TypeScript |
| Performance | Excellent (compiled) | Good (JSI/Fabric) |
| UI Consistency | Pixel-perfect cross-platform | Native components |
| Hot Reload | Excellent | Excellent |
| Hiring Pool | Smaller (Dart) | Massive (JS/TS) |
| Web Support | Good (Flutter Web) | Experimental |
| Ecosystem | pub.dev | npm (massive) |
The Verdict
Use Flutter if: You want the best performance, pixel-perfect UI, or plan to target web + desktop too. Teams willing to learn Dart.
Use React Native if: Your team knows React/JavaScript, you want the largest ecosystem, or hiring Dart developers is impractical.
Consider: For simple apps, a PWA might be enough. For complex native features, consider going fully native.
React Native wins on ecosystem and hiring. JavaScript developers are everywhere. The React mental model transfers directly. Expo has closed the DX gap. Flutter is technically impressive but Dart is a harder sell for most teams.
