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

A Sink that supports adding errors.

This makes it suitable for capturing the results of asynchronous computations, which can complete with a value or an error.

The EventSink has been designed to handle asynchronous events fromStreams. See, for example, Stream.eventTransformed which usesEventSinks to transform events.
