Flutter vs. React Native vs. SwiftUI vs. Uno Platform Comparison Chart

Flutter is Google’s UI toolkit for building beautiful, natively compiled applications for mobile, web, and desktop from a single codebase. Paint your app to life in milliseconds with Stateful Hot Reload. Use a rich set of fully-customizable widgets to build native interfaces in minutes. Quickly ship features with a focus on native end-user experiences. Layered architecture allows for full customization, which results in incredibly fast rendering and expressive and flexible designs. Flutter’s widgets incorporate all critical platform differences such as scrolling, navigation, icons and fonts, and your Flutter code is compiled to native ARM machine code using Dart's native compilers. Flutter's hot reload helps you quickly and easily experiment, build UIs, add features, and fix bugs faster. Experience sub-second reload times without losing state on emulators, simulators, and hardware.

SwiftUI helps you build great-looking apps across all Apple platforms with the power of Swift — and surprisingly little code. You can bring even better experiences to everyone, on any Apple device, using just one set of tools and APIs. Build sophisticated animations with expanded animation support. Use phases to create sequences of animations, or create multiple animation tracks using keyframes. SwiftUI automatically transfers the velocity of a user gesture to your animations so your app feels fluid and natural. Share more of your SwiftUI code with your watchOS apps. Scroll vertical TabViews using the crown, match colors with adaptive background containers, take advantage of edge-to-edge displays with new ToolbarItem placements, and leverage NavigationSplitView to build detailed list views.
