debugGroupFanOutIsLive property

  1. @visibleForTesting
bool get debugGroupFanOutIsLive

Whether the group-scoped fan-out is currently live.

Exposes lifecycle only — the property that actually matters (#445) is that FileDownloader().updates stays listenable for the host, and that is asserted directly rather than through this.

Implementation

@visibleForTesting
static bool get debugGroupFanOutIsLive {
  final c = _groupUpdates;
  return c != null && !c.isClosed;
}
