onChange property
A stream that emits the current state when it changes.
Example
// First, create the Store
final store = new Store<int>(counterReducer, 0);
// Next, listen to the Store's onChange stream, and print the latest
// state to your console whenever the reducer produces a new State.
//
// We'll store the StreamSubscription as a variable so we can stop
// listening later.
final subscription = store.onChange.listen(print);
// Dispatch some actions, and see the printing magic!
store.dispatch("INCREMENT"); // prints 1
store.dispatch("INCREMENT"); // prints 2
store.dispatch("DECREMENT"); // prints 1
// When you want to stop printing the state to the console, simply
`cancel` your `subscription`.
subscription.cancel();
Implementation
@override
Stream<S> get onChange {
final stream = _devToolsStore!.onChange
.map((devToolsState) => devToolsState.currentAppState);
return _distinct ? stream.distinct() : stream;
}
