Dart超时后如何取消订阅原始流？

Question

I have a broadcast stream that I subscribe to it with the timeout:

final s = originBroadcast.timeout(timeout, onTimeout: (sink) => sink.close());
await for (final event in s) {
  ...
}

The problem is that timeout() creates another stream ( s ), and when I unsubscribe or timeout appeared, it doesn't cancel the original stream ( originBroadcast ). Is it possible to do this?

Answer 1

I found a workaround:

final s = originBroadcast.timeout(
  timeout,
  onTimeout: (sink) => sink.close(),
);
s.listen((event) {...});
