Actions

Actions dictate how a widget functions. They are divided into two types: Predefined and User-defined. You can override either type, allowing you to tailor the behavior of the widget to fit your specific needs.

While the CometChatConversationsWithMessages widget does not have its actions, its sub-widgets - Conversation, Messages, and Contacts - each have their own set of actions.

The actions of these widgets can be overridden through the use of the Configurations object of each widget. Here is an example code snippet.

Dart

CometChatConversationsWithMessages(
  conversationsConfiguration: ConversationsConfiguration(
      onItemTap: (conversation) {
        // TODO("Not yet implemented")
      }
  ),
)

Filters

Filters allow you to customize the data displayed in a list within a Widget. You can filter the list based on your specific criteria, allowing for a more customized. Filters can be applied using RequestBuilders of Chat SDK.

While the CometChatConversationsWithMessages widget does not have filters, its widgets do, For more detail on individual filters of its widget refer to Conversations Filters and Messages Filters.

By utilizing the Configurations object of its widgets, you can apply filters.

In the following example, we're filtering Conversation to only show User

Dart

CometChatConversationsWithMessages(
  conversationsConfiguration: ConversationsConfiguration(
    conversationsRequestBuilder: ConversationsRequestBuilder()
        ..limit = 5
        ..conversationType = "user"
  ),
)

Events

Events are emitted by a Widget. By using event you can extend existing functionality. Being global events, they can be applied in Multiple Locations and are capable of being Added or Removed.

The CometChatConversationsWithMessages does not produce any events but its subwidget does. For a full list of these events, you can refer to Conversations events and Messages events.

In the following example, we're incorporating observers for the ConversationDeleted event of Conversations widget.

This ccConversationDeleted will be emitted when the user deletes a conversation

Dart

import 'package:cometchat_chat_uikit/cometchat_chat_uikit.dart';

class _YourScreenState extends State<YourScreen> with CometChatConversationEventListener {

  @override
  void initState() {
    super.initState();
    CometChatConversationEvents.addConversationListListener("listenerId", this); // Add the listener
  }

  @override
  void dispose(){
    super.dispose();
    CometChatConversationEvents.removeConversationListListener("listenerId"); // Remove the listener
  }

  @override
  void ccConversationDeleted(Conversation conversation) {
    // TODO("Not yet implemented")
  }
}
