start method
void
start()
Subscribes to store changes and loads the first page. A repeated call does nothing; to load again, use reload.
Implementation
void start() {
if (isStarted) return;
// Subscribe before loading: otherwise an entry between the query and the subscription is lost.
_changesSubscription = reader.changes.listen(_onStoreChange, onError: _onStoreChangesError);
unawaited(_loadFirstPage());
}
