addReference(Object object) → void: Reference is passed by given object, but only Object.hashCode is store, to prevent 'shady' two way referencing (so native GC will not be affected). When there is 1 or more reference then preferSoftDispose is set.
clear() → void: Clears all references. So preferSoftDispose is not set.
dispose() → void: Used to clear and dispose object. After this method call is object typically unusable and ready for GC. Can be called multiple times!
override
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
removeReference(Object object) → void: Removes reference of given object. When there is 1 or more reference then preferSoftDispose is set.
requestDispose([dynamic parent]) → void: Executes dispose based on preventDispose and preferSoftDispose settings. parent - actual object that requesting dispose.
override
softDispose() → void: Just soft dispose - stop loading / subscriptions etc. For example called when List item hides and is recycled. Also useful when Control is used with multiple Widgets to prevent fatal dispose.
inherited
toString() → String: A string representation of this object.
