/**
 * @assertion StreamController.broadcast({void onListen(), void onCancel(),
 *                                       bool sync: false})
 * If sync is false, the event will always be fired at a later time, after
 * the code adding the event has completed. In that case, no guarantees are
 * given with regard to when multiple listeners get the events, except that
 * each listener will get all events in the correct order. Each subscription
 * handles the events individually. If two events are sent on an async
 * controller with two listeners, one of the listeners may get both events
 * before the other listener gets any. A listener must be subscribed both when
 * the event is initiated (that is, when add is called) and when the event is
 * later delivered, in order to receive the event.
 *
 * @description Checks that if sync is false, each listener will get all
 * events in the correct order.
