Interactive Messages

An InteractiveMessage is a specialized object that encapsulates an interactive unit within a chat message, such as an embedded form that users can fill out directly within the chat interface. This enhances user engagement by making the chat experience more interactive and responsive to user input.

InteractiveMessage is a chat message with embedded interactive content. It can contain various properties:

Parameter	Description
receiverId	The UID or GUID of the recipient
receiverType	The type of the receiver to whom the message is to be sent i.e CometChatConstants.RECEIVER_TYPE_USER (user) or CometChatConstants.RECEIVER_TYPE_GROUP (group)
messageType	The type of the message that needs to be sent
interactiveData	A JSONObject holding structured data for the interactive element
allowSenderInteraction	A boolean determining whether the message sender can interact with the message, by default, it is set to false
interactionGoal	An InteractionGoal object encapsulating the intended outcome of interacting with the InteractiveMessage, by default, it is set to none

Interaction

An Interaction represents a user action involved with an InteractiveMessage. It includes:

• elementId: An identifier for a specific interactive element.
• interactedAt: A timestamp indicating when the interaction occurred.

Mark as Interacted

This method marks a message as interacted by identifying it with the provided Id. it also logs the interactive element associated with the interaction.

Dart

await CometChat.markAsInteracted(messageId, interactedElementId, 
                         onSuccess: (String message ){
                           //write code here for after success

                         }, onError: 
                         (CometChatException excep){
                           //write code here for after err

                         });

Goal Completion

A key feature of InteractiveMessage is checking whether a user's interactions with the message meet the defined InteractionGoal

Any Interaction	The goal is considered completed if there is at least one interaction.	InteractionGoalType.anyAction
Any of Specific Interactions	The goal is achieved if any of the specified interactions occurred.	InteractionGoalType.anyOf
All of Specific Interactions	The goal is completed when all specified interactions occur.	InteractionGoalType.allOf
None	The goal is never completed	InteractionGoalType.none

You would be tracking every interaction users perform on an InteractiveMessage (captured as Interaction objects) and comparing those with the defined InteractionGoal. The completion of a goal can vary depending on the goal type:

This user interaction tracking mechanism provides a flexible and efficient way to monitor user engagement within an interactive chat session. By defining clear interaction goals and checking user interactions against these goals, you can manage user engagement and improve the overall chat experience in your CometChat-enabled application.

InteractionGoal

The InteractionGoal represents the desired outcome of an interaction with an InteractiveMessage. It includes:

• elementIds: A list of identifiers for the interactive elements.
• type: The type of interaction goal from the CometChatConstants.

Sending InteractiveMessages

The InteractiveMessage can be sent using the sendInteractiveMessage method of the CometChat class. The method requires an InteractiveMessage object and a CallbackListener for handling the response.

Here is an example of how to use it:

dart

final Map<String, dynamic> interactiveData = {
  "title": "Survey",
  "formFields": [
    {
      "elementType":  "textInput" ,
      "elementId": "name",
      "optional": false,
      "label": "Name",
      "placeholder": {
        "text": "Enter text here"
        }
    },
    {
      "elementType":  "textInput",
      "elementId": "age",
      "optional": true,
      "label": "Age",
      "maxLines": 1,
      "placeholder": {
        "text": "Enter text here"
        }
    },
    {
      "elementType":  "Select",
      "elementId": "checkBox1",
      "optional": true,
      "label": "Check box element",
      "defaultValue":["chk_option_2"],
      "options" : [
        {
          "label": "Option 1",
          "value": "chk_option_1",
        },
        {
          "label": "Option 2",
          "value": "chk_option_2",
        }

      ]
    },
    {
      "elementType": "dropdown",
      "elementId": "gender",
      "optional": false,
      "label": "Gender",
      "defaultValue":"male",
      "options" : [
        {
          "label": "Male",
          "value": "male",
        },
        {
          "label": "Female",
          "value": "female",
        }

      ]
    },
  ],
  "submitElement": {
    "elementType": "button",
    "elementId": "submitButton",
    "buttonText": "Submit",
    "disableAfterInteracted": false,
    "action": {
      "actionType": "urlNavigation",
      "url": "https://www.cometchat.com/",
    }
  },
};



InteractiveMessage interactiveMessage =
InteractiveMessage(interactiveData: interactiveData,
                   receiverUid: "cometchat-uid-3", //Replace this with receiver id
                   type: "form",
                   receiverType: "user",//replace this with receiver type
                   allowSenderInteraction: true,
                   muid: DateTime.now().millisecondsSinceEpoch.toString(),
                   interactionGoal: InteractionGoal(
                     type: InteractionGoalType.none
                   )
                  );


CometChat.sendInteractiveMessage(interactiveMessage, onSuccess: (InteractiveMessage message){

print(interactiveMessage);

}, onError: (CometChatException excep){
print(excep);
});

Event Listeners

CometChat SDK provides event listeners to handle real-time events related to InteractiveMessage.

On InteractiveMessage Received

The onInteractiveMessageReceived event listener is triggered when an InteractiveMessage is received.

Here is an example:

Dart

class DemoClass with MessageListener{

String listenerId = "UNIQUE_LISTENER_ID"; //Replace with unique listener id


CometChat.addMessageListener(_listenerId, this);



  @override
void onInteractiveMessageReceived(InteractiveMessage message){

  //TODO  implement onInteractiveMessageReceived event 
}

}

On Interaction Goal Completed

The onInteractionGoalCompleted event listener is invoked when an interaction goal is achieved.

Here is an exampl

Dart

class DemoClass with MessageListener{

String listenerId = "UNIQUE_LISTENER_ID"; //Replace with unique listener id


CometChat.addMessageListener(_listenerId, this);



@override
void onInteractionGoalCompleted(InteractionReceipt receipt) {
  //TODO implement onInteractionGoalCompleted
}

}

These event listeners offer your application a way to provide real-time updates in response to incoming interactive messages and goal completions, contributing to a more dynamic and responsive user chat experience.

Usage

An InteractiveMessage is constructed with the receiver's UID, the receiver type, the interactive type, and interactive data as a JSONObject. Once created, the InteractiveMessage can be sent using CometChat's sendInteractiveMessage() method. Incoming InteractiveMessages can be received and processed via CometChat's message listener framework.
