I’m following a tutorial on Flutter Bloc and I’m having an issue with the stream_transform library.

I copied the exact code from the tutorial but I’m still getting an error:

EventTransformer<E> throttleDroppable<E>(Duration duration) {
  return (events, mapper) {
    return droppable<E>().call(events.throttle(duration), mapper);
  };
}

the function ‘droppable’ isn’t defined.

Does this have something to do with the library?

Imports don’t seem to be the issue…
