StreamIterator class - dart:async library (original) (raw)

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 moveNexthas completed with true, and only until moveNext is called again.
