Kommunicate provides build conversation function to create and launch conversation directly. It saves your extra steps of authentication, creation, initialization, and launch. You can customize the process by building the conversation object according to your requirements.

To launch the conversation you need to create a conversation object. This object is passed to the build conversation function and based on the parameters of the object the conversation is created/launched.

Below is an example to launch a conversation.

dynamic conversationObject = {
     'appId': '<APP_ID>',// The [APP_ID]( obtained from kommunicate dashboard.

        .then((clientConversationId) {
      print("Conversation builder success : " + clientConversationId.toString());
    }).catchError((error) {
      print("Conversation builder error : " + error.toString());
