The growing demand for mobile and web applications has given rise to a plethora of programming tools, made available to the developers who want to create those applications. A prominent one among these is Flutter. Flutter is Google's mobile UI framework for crafting high-quality native interfaces on iOS, Android, web, and desktop. Flutter works with existing code, is used by developers and organizations around the world, and is free and open source. Flutter lets you control every pixel on the screen, and its powerful compositing capabilities let you overlay and animate graphics, video, text and controls without limitation. It is fast, easy to learn and work with, and productive.
