isWeak property

@override bool get isWeak

Whether this reference is marked as weak (not strong). See isStrong.

NOTE: This does NOT verify if the target is still reachable (see isAlive). It only checks that no strong reference exists and a weak reference object is present. The referenced object may already have been garbage-collected.

Implementation

@override
bool get isWeak => _strongRef == null && _weakRef != null;
