An Iterator-like interface for the values of a Stream.
This wraps a Stream and a subscription on the stream. It listens
on the stream, and completes the future returned by moveNext when the
next value becomes available.
The stream may be paused between calls to moveNext.
The current value must only be used after a future returned by moveNext
has completed with
true, and only until moveNext is called again.
The current value of the stream.
The hash code for this object.
A representation of the runtime type of the object.
Cancels the stream iterator (and the underlying stream subscription) early.
Wait for the next stream value to be available.
Invoked when a nonexistent method or property is accessed.
A string representation of this object.
