+## Blank screen when channel gets delete
+
+When a channel is deleted, and if some user is active on that channel, a blank screen appears by default (as per the default logic) as we return `null` in this case.

You can implement such UX by listening to `channel.deleted` event on channel screen, and navigate to channel list screen with appropriate notification on app.

+    // add your action here
+  }
