The core difference: how the interface is drawn
The decisive difference is how the interface is produced. Flutter draws every pixel directly with its own rendering engine; the same code produces the same output on iOS and Android. React Native uses the platform's native components, which makes the app feel more platform-native but adds the burden of fixing two platforms separately.
Comparison table
| Criterion | Flutter | React Native |
|---|---|---|
| Interface rendering | Own engine (Skia/Impeller) | Platform native components |
| Language | Dart | JavaScript / TypeScript |
| Cross-platform consistency | High — identical output | Medium — platform differences appear |
| Team learning curve | Dart must be learned | React teams adapt quickly |
| Package ecosystem | pub.dev, mature | npm, very broad |
| Web support | Available, limited use | Possible via React Native Web |
| Animation and custom UI | Strong — full engine control | More limited due to the native bridge |
| Hardware access | Requires platform channels | Requires platform channels |
When to choose Flutter
- When you want identical interface and behaviour on both platforms.
- When custom animation and brand-driven interfaces matter; Flutter controls the rendering engine directly.
- When the team is starting mobile from scratch; learning Dart costs less than managing two platforms separately.
- For interface-heavy apps such as card games, dashboards and catalogues.
When to choose React Native
- When the team has strong React and TypeScript experience; the same mental model carries over to mobile.
- When the app should match the platform's own look exactly.
- When sharing business logic between web and mobile is planned.
- When you depend on a specific library in the npm ecosystem.
When neither is right
For games requiring heavy 3D graphics or a physics engine, a dedicated engine such as Unity fits better. For apps needing low-level hardware access — advanced camera processing, AR or custom Bluetooth protocols — native deserves consideration. If you target a single platform and the newest platform-specific features are critical, native retains its advantage.
Our choice and why
All four mobile products we have shipped were built with Flutter: DrapeAI, Trendela, 13: Jack Hunt and Decidio. We chose it because interface consistency is our highest-priority criterion. Fixing a component that behaves differently on two platforms takes far more time in real projects than teams expect.
