EventSink<T> class
Null safety
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 from
Streams. See, for example, Stream.eventTransformed which uses
EventSinks to transform events.
