asyncMap<E> method
Creates a new stream with each data event of this stream asynchronously mapped to a new event.
This acts like map, in that convert
function is called once per
data event, but here convert
may be asynchronous and return a Future.
If that happens, this stream waits for that future to complete before
continuing with further events.
The returned stream is a broadcast stream if this stream is.
Implementation
@override
Stream<E> asyncMap<E>(FutureOr<E> convert(T event))
=> origin.asyncMap(convert);
