Flutter is Google's cross-platform mobile development framework that allows building native Android and iOS apps from a single codebase using the Dart programming language. It uses widgets to build apps with rich animations and designs, and provides plugins to access native platform features through platform channels. Flutter is well-suited for apps targeting both platforms with complex UI, though it has limitations around app size and 3D support.

For many trivial tasks, plugins are available
For app specific requirements, native code can be
added using Platform Channel
