🐛 Bug Report: RealtimeSubscription fails to work when document is being listened to multiple times by the same client

### 👟 Reproduction steps - Appwrite Console 1.4.3 (Self-hosted) - Flutter 3.13.6 - Dart 3.1.3 Plugins: - appwrite: ^11.0.0 - dart_appwrite: ^10.0.0 - - - # Let's get some stuff done first ## 1. Create a database with the ID `itemListDatabaseId` ## 2. Create a collection inside it with the ID `itemListCollectionId` ## 3. Add some random attributes (e.g. _name_) ## 4. Create a new document with the ID `myNewDocument` ## 5.

Copy paste the following code into your Flutter project and implement the remaining TODO ``` class ItemListViewScreen extends StatefulWidget { const ItemListViewScreen({super.key}); @override State<ItemListViewScreen> createState() => _ItemListViewScreenState(); } class _ItemListViewScreenState extends State<ItemListViewScreen> { RealtimeSubscription? realtimeSubscription; @override void initState() { super.initState(); realtimeSubscription = realtime.subscribe([ 'databases.[itemListDatabaseId].collections.[itemListCollectionId].documents' ]); realtimeSubscription?.stream.listen( (event) { // print('event: $event'); }, ); } @override void dispose() { realtimeSubscription?.close(); super.dispose(); } @override Widget build(BuildContext context) { // TODO: 1. implement showing the items // TODO: 2. add interactivity to open [ItemVie…
