how to subscribe collection
TL;DR
To subscribe to a collection using Appwrite's Realtime feature, follow these steps:
1. Import the necessary dependencies in your project:
```dart
import 'package:appwrite/appwrite.dart';
```
2. Initialize the Appwrite client with the endpoint and project ID:
```dart
final client = Client()
.setEndpoint('https://cloud.appwrite.io/v1')
.setProject('[PROJECT_ID]');
```
Replace `[PROJECT_ID]` with your actual project ID.
3. Create an instance of the Realtime class:
```dart
final realtime = Realtime(client);
```
4. Subscribe to the
You can, For example
TypeScript
import 'package:appwrite/appwrite.dart';
final client = Client()
.setEndpoint('https://cloud.appwrite.io/v1')
.setProject('[PROJECT_ID]');
final realtime = Realtime(client);
final subscription = realtime.subscribe(['databases.DB_ID.collections.COLLECTION_ID.documents']);
subscription.stream.listen((response) {
// Callback will be executed on all account events.
print(response);
})
Replace DB_ID with your database ID, and COLLECTION_ID with your collection ID.
