LeakDetector is a Flutter/Dart package designed to identify memory leaks in widgets, elements, and states. It helps developers detect when UI components are not being properly disposed of, which can lead to increased memory usage and performance degradation. By integrating it into your app, you can monitor for retained references that prevent garbage collection. The tool is particularly useful during development and testing phases to ensure efficient memory management. It supports Android, iOS, and macOS platforms.
