Project objectives #
The Dispatcher allows you to easily publish data and notify multiple listeners at once
The main idea is to behave like a light-weight Kafka producer/consumer API.
The content published on the Dispatcher feeds is dynamic,
which means you can publish basic values (int, String, etc.)
or decide to use it as an Event-driven publisher (if you use custom event objects)
You can create multiple feeds and multiple subscription for each feed.
Example #
var dispatcher = Dispatcher(); // The Dispatcher is a singleton, calling the constructor always returns the same instance
var feedName = 'myIntegerFeed';
var subscriberName = 'mySubscriber';

dispatcher.createFeed(feedName);

dispatcher.subscribeTo(feedName, subscriberName, (feedItem) {
print('value : ${feedItem.value}');
});

dispatcher.publish(feedName, 5);

// -> prints 'value : 5'

dispatcher.unsubscribeTo(feedName, subscriberName);

dispatcher.publish(feedName, 3);

// -> nothing happens, we 'testSubscriber' was unsubscribed
