We've shipped apps in both frameworks across FinTech, HealthTech, and eCommerce. Here's our unfiltered take on which one wins — and when the answer isn't what you expect.
This debate gets rehashed every year, but after building 40+ cross-platform apps across both frameworks — many for the same categories of clients — we have concrete, experience-backed opinions. Neither is universally better. The right choice depends on your team, timeline, and product type.
Performance in Real-World Apps
Flutter's compiled Dart code and Skia rendering engine give it a slight edge in animation-heavy and graphics-rich interfaces. React Native's JSI bridge (introduced in the New Architecture) has closed the gap significantly, but Flutter still feels more 'native-smooth' in scroll-heavy or animation-intensive apps like fitness trackers and dashboards.
Developer Productivity
If your team already knows JavaScript or TypeScript, React Native's learning curve is dramatically lower. Flutter requires Dart — a language most developers need to learn from scratch. For teams starting fresh, Dart is clean and well-documented, but expect a 4–6 week ramp-up before full productivity.
Ecosystem & Packages
React Native wins on ecosystem size — npm's package count dwarfs pub.dev. However, Flutter's official packages from Google are exceptionally well-maintained, and the quality-per-package ratio is arguably higher. For niche integrations (payment SDKs, hardware interfaces), React Native still has broader coverage.
When to Choose Flutter
- Your app is heavily visual or animation-dependent
- You're targeting iOS, Android, and web from one codebase
- Your team is small and you want maximum code sharing
- You're in HealthTech, EdTech, or any domain needing pixel-perfect custom UI
When to Choose React Native
- Your team is already JavaScript/TypeScript native
- You need to share significant logic with an existing web frontend
- You need extensive third-party SDK integration quickly
- You're building a FinTech or marketplace app where ecosystem breadth matters
At First Code Technologies, we've defaulted to Flutter for new greenfield projects in 2025 due to its improved stability and Google's strong investment in the framework. But we deliver in React Native when client teams prefer it or existing codebases require it.
