Let’s skip the marketing fluff. If you are building a cross-platform mobile app, both Flutter and React Native are powerhouses, but they serve completely different workflows.
Flutter is your go-to if you want pixel-perfect UI consistency across Android and iOS out of the box. Its Skia/Impeller rendering engine gives you incredibly smooth 60fps animations, but you have to write in Dart. React Native wins if you want to tap into the massive JavaScript/TypeScript ecosystem and leverage native device components natively.
The Verdict: Need custom, highly animated, custom-designed interfaces? Go Flutter. Need deep integration with web apps and massive JS libraries? Go React Native.
