Support for detecting and being notified when an object is mutated.
There are two kinds of change notifiers:
AsyncChangeNotifier: be notified of a continuous stream of events over time.
ChangeNotifier: be notified at the moment of a change. This is a direct extraction of
ChangeNotifierin Flutter Core.
Some suggested uses for this library:
- Observe objects for changes, and log when a change occurs
- Optimize for observable collections in your own APIs and libraries instead of diffing
- Implement simple data-binding by listening to streams
There are two general ways to detect changes:
- Listen to
ChangeNotifier.changesand be notified when an object changes
