What are the pros and cons of using Flutter vs React Native for cross-platform apps?

All answers to this question.

The "bridge" in React Native is being replaced by the JSI (JavaScript Interface), which has narrowed the performance gap considerably. Flutter still feels slightly smoother for UI-heavy apps with complex animations because it controls every pixel on the screen. However, React Native wins on ecosystem and "Web to Mobile" skill transfer. If your team already knows React, the learning curve for RN is minimal. Flutter requires learning Dart, which is a great language but another hurdle.

Are you planning to integrate many native modules, like custom Bluetooth drivers or complex AR features, that might require writing native Swift or Kotlin?

• If you're going deep into native hardware, React Native's community has more "ready-made" bridges. Flutter is getting there, but for niche hardware, you'll likely end up writing more platform-specific code. For 90% of business apps (CRUD, Auth, Maps), both are excellent. Flutter's developer experience (DX) with Hot Reload is still slightly superior in my opinion.

Flutter’s UI consistency is its biggest pro. It looks the same on every device. React Native uses native components, which can sometimes lead to slight layout shifts.

• Very true, Mark. If your designers are perfectionists about "pixel-perfect" layouts across all devices, Flutter will save you a lot of headache in CSS/Style adjustments
