StreamSinkCompleter<T> class Null safety

A sink where the destination is provided later.

The sink is a normal sink that you can add events to to immediately, but until setDestinationSink is called, the events will be buffered.

The same effect can be achieved by using a StreamController and adding it to the sink using Sink.addStream when the destination sink is ready. This class attempts to shortcut some of the overhead when possible. For example, if the sink only has events added after the destination sink has been set, those events are added directly to the sink.
