Receive a Chat Message

To be able to receive chat messages you need to implement a method onChatUpdates(...) method from callback RtkChatEventListener. You can subscribe to this events by calling meeting.addChatEventListener(rtkChatEventListener)

class ChatEventListener extends RtkChatEventListener {
  @override
  void onChatUpdates(List<ChatMessage> messages) {
    messages.map((msg) {
      switch (msg.type) {
        case MessageType.text:
          print((msg as TextMessage).displayName);
          print((msg).message);

          // Show message/return state to show text message UI.

          break;
        case MessageType.image:
          print((msg as ImageMessage).displayName);
          print((msg).link);

          // Show message/return state to show image message UI.
          break;
        case MessageType.file:
          print((msg as FileMessage).name);
          print((msg).link);
          print((msg).size);
          // Show message/return state to show file message UI.

          break;
      }
    });
  }

  void onNewChatMessage(ChatMessage message) {
      // your code to handle new chat message
  }
}

In this context, messages refers to a list of all the chat messages in the meeting. The type of message used is ChatMessage, which was introduced earlier in the introduction to Chat topic.

Whenever a chat message is received, the meeting.chat.messages list is automatically updated.
