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
DrapeAI, 13: Jack Hunt, Decidio and Trendela are all built with Flutter. We chose it because interface consistency is our highest-priority criterion. Fixing a component that behaves differently on two platforms takes far more time than teams expect.
Questions
- Is Flutter or React Native faster?
- For interface and logic-driven apps, users perceive no meaningful speed difference. Because Flutter draws the interface with its own engine there is no bridge layer, which helps on animation-heavy screens. React Native's new architecture has largely closed that gap.
- Which should we pick if we already have a React team?
- If your team has strong React and TypeScript experience, React Native shortens ramp-up time; the same mental model applies. But if identical interfaces across both platforms are critical, Flutter carries less maintenance burden long-term despite the cost of learning Dart.
- When is native development necessary instead of cross-platform?
- Native is the better call for games requiring heavy 3D graphics or a physics engine, and for apps needing low-level hardware access such as advanced camera processing, AR or custom Bluetooth protocols. It also has the edge when you target a single platform and the newest platform-specific features matter.
