Cross-Platform Mobile Development: React Native vs Flutter in 2024
The cross-platform mobile development landscape has matured dramatically. React Native and Flutter now power some of the world's most popular apps, from Meta's own apps to Google Pay, Alibaba to BMW. The question isn't whether cross-platform can deliver production-quality apps—it's which framework fits your team and project best.
This guide provides a comprehensive comparison to help you make an informed technology decision.

When to Choose Each Framework
Choose React Native When:
Best Fit for React Native:
- Your team has JavaScript/React expertise
- You need maximum native look and feel
- You're building for web, iOS, and Android
- You want access to React's vast ecosystem
- You need brownfield integration (adding to existing native app)
Choose Flutter When:
Best Fit for Flutter:
- You want consistent UI across platforms
- Performance is critical (animations, graphics)
- You're starting greenfield development
- You need a single codebase for mobile, web, and desktop
- Custom, branded UI is more important than native feel
Project Timeline Comparison
Setup & Architecture
Project setup, architecture decisions, CI/CD configuration. Flutter slightly faster setup.
Core Features
Building main app functionality. Similar velocity for both frameworks.
Platform Integration
Native modules, permissions, platform-specific features. React Native often easier.
Polish & Testing
UI refinement, testing, bug fixes. Flutter's consistent rendering helps.

Migration Considerations
Migrating to Cross-Platform
Assess
Evaluate current codebase, team skills, app requirements
Pilot
Build one feature or screen in target framework
Bridge
Integrate cross-platform module into native app
Migrate
Progressively move features to cross-platform
Complete
Full migration when majority of app is cross-platform
Future Outlook
React Native Roadmap
- New Architecture: Fabric renderer and TurboModules for better performance
- Hermes Default: Faster JavaScript engine
- Web Convergence: Better React Native for Web support
Flutter Roadmap
- Impeller: New rendering engine for smoother animations
- WASM: WebAssembly support for web performance
- Desktop Maturity: First-class Windows, Mac, Linux support
Decision Framework
Assess Team Skills
JavaScript/React expertise favors RN. Dart learning curve is manageable for Flutter.
Define Requirements
Native feel needs favor RN. Custom UI and animations favor Flutter.
Consider Ecosystem
Evaluate available packages for your specific needs.
Build Prototype
Build the same feature in both to experience the difference.
