onChange property
Stream<St>
onChange
A stream that emits the current state when it changes.
Example
// Create the Store;
final store = new Store<int>(initialState: 0);
// Listen to the Store's onChange stream, and print the latest
// state to the console whenever the reducer produces a new state.
// Store StreamSubscription as a variable, so you can stop listening later.
final subscription = store.onChange.listen(print);
// Dispatch some actions, which prints the state.
store.dispatch(IncrementAction());
// When you want to stop printing, cancel the subscription.
subscription.cancel();
Implementation
Stream<St> get onChange => _changeController.stream;
