Flutter SDK

Flutter is an open‑source UI toolkit that lets developers create natively compiled applications for mobile, web, desktop and embedded devices from a single codebase. It uses the Dart programming language, which compiles to ARM, Intel and JavaScript targets, providing fast performance on a wide range of hardware. The framework includes a rich set of widgets and a rendering engine that give fine‑grained control over pixel‑level layout, enabling adaptive designs that work on any screen size.

The development workflow is supported by features such as Hot Reload, which updates code instantly while preserving application state, and a suite of testing and tooling utilities that help maintain production‑quality code. Flutter integrates with Google services—including Firebase, Google Maps, and Google Pay—allowing developers to incorporate backend, analytics and payment capabilities without leaving the framework.

Flutter is maintained by Google and a global community of contributors, and it is used by many well‑known brands. Its stable, cross‑platform nature makes it suitable for teams that need to reach users on mobile, web, desktop and embedded platforms while keeping a shared codebase.
