Flutter is a mobile sdk, built and open-sourced by Google, that, at its core, is about empowering everyone to build beautiful mobile apps. Whether you come from the world of web development or native mobile development, Flutter makes it easier than ever to create mobile apps in a familiar, simplified way. Flutter is special in that it makes it truly capable to "write once, and deploy everywhere". As of this writing, Flutter apps will deploy to Android, iOS, and ChromeOS. In the near future, Flutter apps will also run as web apps and Desktop apps on all major operating systems.

In short, Flutter is a truly complete SDK for creating applications. It’s a platform that provides everything you need to build applications: the rendering engine, UI components, testing frameworks, tooling, a router, and many more features that you need to create an application. The consequence is that you get to focus on the interesting problems in your app. You can focus specifically on the domain functionality, and everything else is taken care of. The value that it provides is astonishing.
