<p>Returns a future which completes when this stream has been consumed
and the consumer has been closed.</p>
<p>The returned future completes with the same result as the future returned
by <a href="dart-async/StreamConsumer/close.html">StreamConsumer.close</a>.
If the call to <a href="dart-async/StreamConsumer/addStream.html">StreamConsumer.addStream</a> fails in some way, this
method fails in the same way.</p>
