EventSubscription<T extends GeneratedMessage> class
Null safety
A subscription for events.
To consume unpacked typed event messages, use eventMessages. To use events with metadata, use events.
To stop receiving updates from the server, invoke unsubscribe. This will cancel the subscription both on the client and on the server, stopping the changes from being reflected to Firebase.
Please note that only broadcast streams are supported. It is a responsibility of end-users to convert any streams to broadcast streams prior to using this class.
