Understanding flutter in easier way

Flutter is a modern, open-source UI toolkit from Google for building natively compiled applications for mobile, web, and desktop from a single codebase. It uses the Dart programming language and a reactive, widget-based architecture to deliver fast development, expressive UIs, and near-native performance.
