observable 0.17.0+1

Support for marking objects as observable

0.17.0+1

• Revert PropertyChangeMixin, which does not work in dart2js

0.17.0

This is a larger change with a goal of no runtime changes for current customers, but in the future Observable will become a very lightweight interface, i.e.:

abstract class Observable<C extends ChangeRecord> {
  Stream<List<C>> get changes;
}

• Started deprecating the wide Observable interface
  • ChangeNotifier should be used as a base class for these methods:
    • Observable.observed
    • Observable.unobserved
    • Observable.hasObservers
    • Observable.deliverChanges
    • Observable.notifyChange
  • PropertyChangeNotifier should be used for these methods:
    • Observable.notifyPropertyChange
  • Temporarily, Observable uses ChangeNotifier
    • Existing users of anything but implements Observable should move to implementing or extending ChangeNotifier. In a future release Observable will reduce API surface down to an abstract Stream<List<C>> get changes.
• Added the ChangeNotifier and PropertyChangeNotifier classes
  • Can be used to implement Observable in a generic manner
• Observable is now Observable<C extends ChangeRecord>
  • When passing a generic type C, notifyPropertyChange is illegal

0.16.0

• Refactored MapChangeRecord
  • Added equality and hashCode checks
  • Added MapChangeRecord.apply to apply a change record
• Added MapDiffer, which implements Differ for a Map

0.15.0+2

• Fix a bug in ListDiffer that caused a RangeError

0.15.0+1

• Fix analysis errors caused via missing /*<E>*/ syntax in 0.15.0

0.15.0

• Added the Differ interface, as well as EqualityDiffer
• Refactored list diffing into a ListDiffer
• Added concept of ChangeRecord.ANY and ChangeRecord.NONE
  • Low-GC ways to expression "something/nothing" changed
• Refactored ListChangeRecord
  • Added named constructors for common use cases
  • Added equality and hashCode checks
  • Added ListChangeRecord.apply to apply a change record
• Added missing @override annotations to satisfy annotate_overrides

0.14.0+1

• Add a missing dependency on pkg/meta.
