cast<S> method
Null safety
override
Returns a copy of this with the generic type coerced to S
.
If any events emitted by stream aren't of type S
, they're converted
into TypeError events (CastError
on some SDK versions). Similarly, if
any events are added to sink that aren't of type S
, a TypeError is
thrown.
Implementation
@override
StreamChannel<S> cast<S>() => StreamChannel(
stream.cast(), StreamController(sync: true)..stream.cast<T>().pipe(sink));
