Garbage Collection

Dart is a client-optimized programming language developed by Google for building user interfaces with event-driven programming. It supports both just-in-time and ahead-of-time compilation for development flexibility and deployment performance. Dart is the programming language behind Flutter, Google's UI toolkit for building applications across multiple platforms.
