FlutterMemoryAllocations class
An interface for listening to object lifecycle events.
If kFlutterMemoryAllocationsEnabled is true, FlutterMemoryAllocations listens to creation and disposal events for disposable objects in Flutter Framework. To dispatch other events objects, invoke FlutterMemoryAllocations.dispatchObjectEvent.
Use this class with condition kFlutterMemoryAllocationsEnabled,
to make sure not to increase size of the application by the code
of the class, if memory allocations are disabled.
The class is optimized for massive event flow and small number of added or removed listeners.
