Creates a wrapper that coerces the type of sink
.
Unlike new StreamSink, this only requires its argument to be an instance
of StreamSink
, not StreamSink<T>
. This means that calls to add may
throw a TypeError if the argument type doesn't match the reified type of
sink
.
Implementation
@Deprecated(
'Use StreamController<T>(sync: true)..stream.cast<S>().pipe(sink)')
static StreamSink<T> typed<T>(StreamSink sink) =>
sink is StreamSink<T> ? sink : DelegatingStreamSink._(sink);
