Dart is a programming language that supports the Flutter development framework for cross-platform apps. It was first published before Flutter.

The size of the app can now be reduced.

Flutter 2.2 will now allow Android apps to include delayed components in an effort to make mobile apps even lighter and less bulky. This manner, the Flutter parts required for the app's correct operation may be downloaded at run-time, eliminating the need to load additional code into the app.

Flutter 2.2 now allows iOS developers to precompile shaders, which makes animations more fluid and seamless (when they are run for 1st time). Furthermore, several new tools have been introduced to allow developers to monitor memory consumption in any app, allowing them to optimise memory usage and improve app performance.
