Flutter is an open-source UI software development kit by Google for creating natively compiled applications across multiple platforms from a single codebase using the Dart language. It was unveiled in 2015, with a stable version released in December 2018, and it supports mobile, web, and desktop development. Key advantages include high performance, immediate updates, and a mild learning curve, though it has drawbacks like large file sizes and limited third-party libraries.
