scope method
Returns the management view of this stream's resource scope
Implementation
@override
StreamManagementScope scope() {
// This is a pragmatic cast. Ideally, StreamManagementScope would implement StreamScope
// or provide a getter for it. This change assumes such compatibility is intended.
// If StreamManagementScope is not meant to be a StreamScope, rcmgr.dart needs adjustment.
return _streamManagementScope ;
