This method constructs an event object and then passes it to :meth:`dispatch_event` for the actual dispatching. :param args: positional arguments to the constructor of the associated event class :param kwargs: keyword arguments to the constructor of the associated event class :returns: an awaitable that completes when all the callbacks have been called (and any awaitables waited on) and resolves to ``True`` if there were no exceptions raised by the callbacks, ``False`` otherwise """
