it pop up randomly

TypeScript
flutter: AppwriteException: , Missing channels (1008)
flutter: 
#0      RealtimeMixin.handleError (package:appwrite/src/realtime_mixin.dart:157:7)
#1      RealtimeMixin._createSocket.<anonymous closure> (package:appwrite/src/realtime_mixin.dart:50:13)
#2      _RootZone.runUnaryGuarded (dart:async/zone.dart:1594:10)

please whats the issue here?
TL;DR
Developers are encountering a 'Missing channels (1008)' error in their Appwrite Flutter app. The solution provided is to check if the channel string is not empty before subscribing. Make sure to set the channel dynamically and handle realtime in the app to avoid this error.

Are you handling realtime in your app?

If so, are you setting the channel dynamically?

yes...

Then, the best would be to check if the channel string is not empty before subscribing, something like so:

TypeScript
if(dynamicChannel.isNotEmpty)
  realtime.subscribe([dynamicChannel]);
