reconnectedStream property
Fires each time the connection comes back after being lost, once it is fully usable again: tracked rooms rejoined and the offline queue flushed.
This is the cue to refetch what may have been missed while it was down —
unless RealtimeReconnection.resumed says the server replayed it. The
first connection of a client never fires it; every later one does,
whether it followed a drop or an explicit disconnect() and connect().
Implementation
@override
Stream<RealtimeReconnection> get reconnectedStream => _reconnectedController.stream;
