done property

@override Future<Outcome<T>> get done

Completes with the outcome; never throws.

Reading it marks the job observed, so nobody is asked to answer for a Failed outcome: the one reading has it. Any read counts, a print or a debugger's watch on the getter as well.

Implementation

@override
Future<Outcome<T>> get done {
  _observed = true;
  return _done.future;
}
