removeObserver method

bool removeObserver(ElementsBindingObserver observer)

Unregisters the given observer. This should be used sparingly as it is relatively expensive (O(N) in the number of registered observers).

See also:

• addObserver, for the method that adds observers in the first place.
• ElementsBindingObserver, which has an example of using this method.

Implementation

bool removeObserver(ElementsBindingObserver observer) => _observers.remove(observer);
