listen method

Future listen(
  1. Stream<T> stream
)

Listens to the given stream and sets the reference's value to whatever is emitted on the stream.

Returns a Future that completes when the stream is done, analogous to StreamController.addStream.

Implementation

Future listen(Stream<T> stream) {
  _listenSub?.cancel();
  _listenSub = stream.listen((v) {
    value = v;
  });
  return _listenSub!.asFuture();
}
