How to use #

Step 1: Create an EventBus #

final bus = EventBus(transformers);

EventBus is from zam_event_bus package.

Step 2: Provide the EventBus #

final app = EventBusProvider(
  bus: bus,
  child: MaterialApp(
    home: MyHomePage(title: 'Event Bus Demo'),
  ),
);
runApp(app);  

Add EventBusProvider before MaterialApp so that it is made available to all the routes.

FloatingActionButton(
  onPressed: () => context.dispatch(IncrementEvent()),
  tooltip: 'Increment',
  child: Icon(Icons.add),
),

Step 4: Use context to listen to values #

context.select<Counter>(), // Gives you a stream of Counter.
