Unable to update stateNotifier when realtime data arrives

What is your code?

TL;DR

User is experiencing an issue with updating stateNotifier when realtime data arrives. The error suggests that the provider cannot be modified in a build function. The user's code includes a stream provider and a method to get the latest message using realtime data. Another user asks for the user's code.

Just a moment

@Steven

Stream<RealtimeMessage> getLatestMessage();

TypeScript

  Stream<RealtimeMessage> getLatestMessage() {
    final realtime = _realtime.subscribe([
      'databases.${AppwriteConstants.databaseId}.collections.${AppwriteConstants.messagesCollection}.documents'
    ]).stream;
    return realtime;
  }
