Does Dart support automatic garbage collection of unused objects?

Yes, Dart supports automatic garbage collection of unused objects in memory through its built-in garbage collector. This means that developers do not need to manually free memory — the Dart runtime environment automatically tracks objects that are no longer referenced and frees the memory they occupy.

The garbage collector in Dart runs in the background and is optimized to minimize pauses in the application's operation, which is especially important for mobile applications built with Flutter.

Therefore, memory management in Dart is automated, simplifying development and reducing the likelihood of errors related to memory leaks.
