Google's cross-platform framework that draws its own interface rather than using the system's native controls, producing iOS, Android, web, and desktop builds from one Dart codebase.
Because Flutter renders everything itself, the result looks pixel-identical on both platforms, which suits products with a strong custom visual identity and heavy animation.
We choose between Flutter and React Native by the product and your team: Flutter for custom-rendered, animation-rich interfaces, React Native when logic and developers are shared with a web product.
