What is Flutter?

Flutter is a free, open source UI toolkit created by Google for building natively compiled applications for mobile, web, and desktop from a single Dart codebase. It ships with a large library of customizable Material and Cupertino widgets, a fast rendering engine, and a hot reload feature that lets developers see code changes in a running app almost instantly.

Because Flutter compiles directly to native ARM or x86 code rather than relying on a JavaScript bridge, apps built with it tend to run smoothly across iOS, Android, Windows, macOS, Linux, and the web. It has no licensing fees, is backed by an active Google team and a large open source community, and integrates easily with Firebase and other backend services.
