We’ve shipped 4 Flutter apps and 3 React Native apps into production since 2022. This isn’t a feature comparison you’ll find in any documentation — it’s the judgment call of engineers who have debugged both in production, fought with both on the App Store review process, and explained both to clients who just wanted their app to be fast.
The Short Answer (For People Who Skip Articles)
If you’re starting a new cross-platform mobile project in 2025:
- Choose Flutter if performance and pixel-perfect UI fidelity are top priorities, or if your team doesn’t have strong JavaScript/TypeScript experience.
- Choose React Native (with Expo) if your team is already strong in the React ecosystem, you need to share business logic with a web app, or you need OTA (over-the-air) updates without App Store submissions.
Performance: Flutter Wins, But Not By As Much As You’d Think
Flutter compiles to native ARM code. Its UI is rendered by the Skia (now Impeller) engine, bypassing native UI components entirely. The result: consistent 60fps (120fps on ProMotion displays) for any animation or transition you build.
React Native’s New Architecture (Fabric + JSI) has closed the gap significantly. In our benchmarks with a complex list view and real-time data updates:
- Flutter: 60fps, 0 dropped frames
- React Native (New Architecture): 58fps average, occasional drops to 52fps under memory pressure
For most apps, this difference is imperceptible to users. It matters if you’re building something with complex animations, games, or custom rendering — in which case Flutter is the clear choice.
Developer Experience: Depends on Your Background
Dart (Flutter’s language) is excellent. It’s strongly typed, has a null safety system that eliminates an entire class of runtime errors, and the hot reload is genuinely fast (under 1 second for most changes). The learning curve for a JavaScript developer is roughly 2–4 weeks to become productive.
React Native’s DX has improved dramatically since Expo SDK 50. The Expo ecosystem handles the painful parts (native module linking, OTA updates, build configuration) with a level of abstraction that makes solo developers highly productive. If your team already writes React for the web, the on-ramp is nearly flat.
The Ecosystem Reality in 2025
Both ecosystems are mature. Both have packages for virtually every common use case (maps, camera, biometrics, payments, push notifications). The gap that existed in 2020 — where Flutter was missing critical packages — is effectively closed.
Where differences remain:
- Maps: Google Maps Flutter plugin is excellent. React Native Maps is also solid but has historically lagged on iOS updates.
- Payment SDKs: Stripe’s Flutter SDK is newer than the React Native one but has caught up. Midtrans (common in Indonesia) has better community packages for React Native.
- Code sharing with web: If you’re building a companion web app, React Native lets you share business logic, state management (Zustand, Redux), and utility functions. This is a significant advantage that Flutter simply can’t match.
Our Recommendation Framework
We run every new mobile project through three questions:
- Does the client have a web app that shares business logic? If yes → React Native.
- Are animations and visual fidelity the core differentiator? If yes → Flutter.
- What does the team actually know well? The productivity difference between an expert team and a learning team is larger than the performance difference between the frameworks.
In 2025, you can build an excellent product with either. The tooling debate is mostly settled. The real differentiator is always your team’s execution, not the framework.
