dart:async

pipe method

Future pipe(StreamConsumer<T> streamConsumer)

Pipe the events of this stream into streamConsumer.

The events of this stream are added to streamConsumer using StreamConsumer.addStream. The streamConsumer is closed when this stream has been successfully added to it - when the future returned by addStream completes without an error.

Returns a future which completes when the stream has been consumed and the consumer has been closed.

The returned future completes with the same result as the future returned by StreamConsumer.close. If the adding of the stream itself fails in some way, then the consumer is expected to be closed, and won't be closed again. In that case the returned future completes with the error from calling addStream.
