Introduction
Choosing between React Native and Flutter is like choosing between a Swiss Army knife and a custom-forged Katana. Both get the job done, but the experience, the feel, and the outcome depend entirely on your mission.
After my last post on building Rust without Visual Studio, I’ve been thinking a lot about "the right tool for the job." Today, we’re putting the two giants of cross-platform development into the ring. No fluff—just 20 hard-hitting differences to help you decide.
The Deep Dive: 20 Points of Difference
| # | Feature | React Native (RN) | Flutter |
|---|---|---|---|
| 1 | Language | JavaScript/TypeScript (The Web King) | Dart (Optimized for UI) |
| 2 | Architecture | Bridge-based (Moving toward JSI) | Skia/Impeller Engine (No bridge) |
| 3 | UI Components | Uses Native OEM components | Draws its own widgets (Pixel perfect) |
| 4 | Performance | Great, but can lag in heavy animations | Excellent (60-120 FPS consistently) |
| 5 | Learning Curve | Easy for Web Devs | Steeper (Learning Dart + Widget tree) |
| 6 | Development Speed | Fast (Hot Reload) | Very Fast (Hot Reload + Hot Restart) |
| 7 | Installation | NPM/Yarn (Standard web flow) | Binary download + Flutter Doctor |
| 8 | Documentation | Community-driven (Can be fragmented) | Official docs are elite & centralized |
| 9 | Ecosystem | Massive (Packages for everything) | Growing fast (Highly curated) |
| 10 | Styling | Flexbox (CSS-like) | In-code widget properties |
| 11 | Navigation | Third-party (React Navigation) | Built-in (Navigator 2.0 / GoRouter) |
| 12 | State Management | Redux, Zustand, Context API | Provider, Riverpod, Bloc |
| 13 | Look & Feel | Native-first (Matches OS updates) | Brand-consistent (Looks same on all) |
| 14 | IDE Support | VS Code (Supreme) | Android Studio / VS Code |
| 15 | App Size | Generally smaller | Generally larger (Engines are heavy) |
| 16 | Stability | Mature, but "Upgrade Hell" is real | Extremely stable; breaking changes rare |
| 17 | Company | Meta (Facebook) | |
| 18 | Web Support | Strong (React Native Web) | Good, but feels "Canvas-y" |
| 19 | Testing | Jest/Detox | Strong built-in Unit/Widget testing |
| 20 | Market Demand | Higher (Enterprise/Legacy) | Surging (Startups/New apps) |
🛡️ React Native: Where It Shines
- The "Web to Mobile" Bridge: If your team knows React, you’re 80% there. You don’t need to learn a new paradigm.
- Truly Native UI: Because it uses actual native components, your buttons look like Apple buttons on iOS and Google buttons on Android without trying.
- Code Sharing: High potential to share logic between your website and your mobile app.
⚠️ React Native: The Pain Points
The Bridge Bottleneck: Passing data between JS and Native layers can cause stuttering in complex apps.
- Version Upgrades: Updating RN versions is notoriously painful and can break your entire project.
🚀 Flutter: Where It Shines
UI Consistency: Your app will look exactly the same on a 2018 Android and a 2025 iPhone. No "OS-specific" CSS hacks.
- Developer Experience (DX): "Flutter Doctor" is a godsend. The tooling is cohesive and feels like a complete product rather than a collection of libraries.
- High-Performance Graphics: Perfect for apps with heavy custom animations or unique branding.
⚠️ Flutter: The Pain Points
Dart: While easy to learn, it’s another language to maintain.
- Proprietary Feel: Because Flutter draws its own UI, it doesn't automatically get the "feel" of new OS updates (like iOS 18's new look) until the Flutter team updates the widgets.
The Verdict: Which one should you pick?
Choose React Native if:
- You have a React-heavy team.
- You need to share code with a web platform.
- You want a "Native-first" look and feel.
Choose Flutter if:
- You want high-performance, custom UI.
- You want a more stable, integrated development environment.
- You’re building a greenfield project and want to move FAST.
