The Cross-Platform Landscape
When building a mobile application, businesses want to target both iOS and Android platforms. Historically, this meant hiring separate native development teams. Cross-platform frameworks have revolutionized this space, allowing developers to share up to 90% of their codebase across platforms.
The two clear leaders are Google’s Flutter and Meta’s React Native.
Performance Comparison
Flutter compiles directly to native ARM and x86 machine code using Dart, bypassing any bridge. This leads to near-native performance and smooth 60fps or 120fps animations.
React Native uses a JavaScript engine to communicate with native elements. While historically slower, the new React Native architecture (with TurboModules and Fabric) has minimized the performance gap significantly.
Ecosystem and Ecosystem Size
- React Native: Leverages the massive JavaScript/React ecosystem. If you have web developers on your team, they can transition to React Native very quickly.
- Flutter: Uses Dart. The package repository (pub.dev) is highly curated and maintained, but developers must learn Dart to build applications.
