## AI overview

This tutorial explains how Dart garbage collection, weak references, and finalizers relate to memory management. It describes how lingering references can retain unused objects, causing memory leaks, poor performance, or app crashes, and introduces weak references and finalizers as ways to reduce common memory-management problems.
