Manage Chat Room Attributes

Chat rooms enable real-time messaging among multiple users.

This page shows how to use the Agora Chat SDK to manage the attributes of a chat room in your app.

Understand the tech

The Agora Chat SDK provides the ChatRoom, ChatRoomManager, and ChatRoomEventHandler classes for chat room management, which allows you to implement the following features:

• Retrieve the announcements of a chat room
• Update the announcements of a chat room
• Update the name of a chat room
• Update the description of a chat room

Prerequisites

Before proceeding, ensure that you meet the following requirements:

• You have initialized the Agora Chat SDK. For details, see Get Started with Flutter.
• You understand the call frequency limit of the Agora Chat APIs supported by different pricing plans as described in Limitations.
• You understand the number of chat rooms supported by different pricing plans as described in Pricing Plan Details.

Implementation

This section describes how to call the APIs provided by the Agora Chat SDK to implement chat room features.

Retrieve the chat room announcements

All chat room members can call fetchChatRoomAnnouncement to retrieve the chat room announcements.

The following code sample shows how to retrieve the chat room announcements:

try {
  String? announcement =
      await ChatClient.getInstance.chatRoomManager.fetchChatRoomAnnouncement(
    roomId,
  );
} on ChatError catch (e) {
}

Update the chat room announcements

Only the chat room owner and admins can call updateChatRoomAnnouncement to set and update the announcements. The length of the chat room announcements can be a maximum of 512 characters. Once the chat room announcements are updated, all the other chat room members receive the ChatRoomEventHandler#onAnnouncementChangedFromChatRoom callback.

The following code sample shows how to update the chat room announcements:

try {
  await ChatClient.getInstance.chatRoomManager.updateChatRoomAnnouncement(
    roomId,
    newAnnouncement,
  );
} on ChatError catch (e) {
}

Update the chat room name

The chat room owner and admins can call changeChatRoomName to set and update the chat room name. The length of a chat room name can be a maximum of 128 characters.

The following code sample shows how to update the chat room name:

try {
  await ChatClient.getInstance.chatRoomManager.changeChatRoomName(
    roomId,
    newName,
  );
} on ChatError catch (e) {
}

Update the chat room description

The chat room owner and admins can call changeChatRoomDescription to set and update the chat room description. The length of a chat room description can be a maximum of 512 characters.

The following code sample shows how to update the chat room description:

try {
  await ChatClient.getInstance.chatRoomManager.changeChatRoomDescription(
    roomId,
    newDesc,
  );
} on ChatError catch (e) {
}
