I've shipped production apps in both React Native and Flutter. I started with React Native in 2021, shipped three apps with it, then deliberately picked up Flutter for QuickShift in 2024 to learn it properly. Here's what I actually think.
The Short Version
If you're a JavaScript/TypeScript developer building a mobile app, use React Native. If you're starting fresh with no existing team or codebase baggage, give Flutter serious consideration — especially if UI fidelity is critical.
Now the longer version.
React Native in 2025
React Native has had a transformative few years. The New Architecture (Fabric renderer + JSI) is now stable and shipping in new projects by default. This addresses the biggest historical criticism — the bridge. Performance for most use cases is now genuinely good.
What I like:
- TypeScript support is first-class and the community tooling around it is excellent
- If you already know React, the mental model transfers almost completely
- Expo has made the development experience dramatically better. OTA updates, EAS build service, and the plugin ecosystem are real productivity multipliers
- The npm ecosystem is available to you — libraries like React Query, Zustand, and Zod work without modification
- Metro bundler is fast enough now
Where it still falls short:
- Complex animations are still easier to get wrong than in Flutter
- Custom native modules require touching native code (Swift/Kotlin), which breaks the "one codebase" promise for non-trivial features
- Web support via React Native Web is functional but feels like a second-class citizen
Flutter in 2025
Flutter is genuinely impressive. After dismissing it for a couple of years, picking it up for QuickShift changed my perspective.
What I like:
- The widget system is consistent and predictable. Everything is a widget, which sounds limiting but actually makes complex UIs very straightforward
- Animations are a first-class feature. The
AnimationControllerAPI and built-in curves make smooth, 60fps animations accessible to any developer - No bridge. Flutter code compiles directly to native ARM. The performance ceiling is higher
- Hot reload is fast. Legitimately one of the best hot reload experiences I've used
- Dart is a well-designed language. Null safety is enforced properly, the async/await model is clean, and it compiles ahead-of-time
Where it still has friction:
- The Dart ecosystem is smaller than npm. If you need a third-party library, there's a real chance it doesn't exist, is unmaintained, or is lower quality than equivalent npm packages
- Coming from JavaScript, Dart feels verbose.
final,const, typed lists, method cascades — it's more to type - The Flutter pub.dev community is active but simply doesn't have the volume of the npm ecosystem
- Web support is better but still feels like it wasn't designed for it from the start
The Real Decision Factor
Forget benchmarks. The actual decision comes down to three things:
1. Your team's existing skills. If you have React developers, React Native will ship faster because the ramp-up is minimal. If you're hiring or starting fresh, this advantage disappears.
2. How important pixel-perfect UI is. Flutter has a genuine edge here. Its widgets render identically on iOS and Android because they don't use native components — Flutter paints everything itself. If your designer has pixel-level opinions, Flutter will make them happier.
3. How much native functionality you need. If your app needs deep integration with native APIs (Bluetooth, background processing, health data, etc.), React Native's bridge can become a liability. Flutter handles this better architecturally.
What I Use Now
For most of my client work, I default to React Native. My speed with it is higher, the client can eventually find other React Native developers to continue the project, and Expo's toolchain is genuinely excellent for shipping and maintaining apps.
I reach for Flutter when the client is specifically building something where UI fidelity is the primary differentiator, or when I have time to invest in doing it properly.
The honest answer is that both are good. The React Native vs Flutter debate in 2025 is much less dramatic than it was in 2021. Both can ship quality apps. The difference comes down to team, project requirements, and personal preference.
Stop overthinking it. Pick one and ship.
