# Message Information

> Message Information — CometChat documentation.

The `CometChatMessageInformation` is a [Widget](/ui-kit/flutter/v4/components-overview#components) designed to display message-related information, such as delivery and read receipts. It serves as an integral part of the CometChat UI UI Kit, extending the [ListBase](/ui-kit/flutter/v4/list-base) class, which provides the underlying infrastructure for CometChat UI widgets. With its rich set of methods and properties, developers can easily customize and tailor the appearance and behavior of the message information widget to suit the specific requirements of their application.

`CometChatMessageInformation` is comprised of the following [Base Widgets](/ui-kit/flutter/v4/components-overview#base-components):

| Base Widgets                              | Description                                                                  |
| ----------------------------------------- | ---------------------------------------------------------------------------- |
| [List Base](/ui-kit/flutter/v4/list-base) | This renders common widgets used across `Conversations`, `Groups` & `Users`. |

## Usage

### Integration

You can launch `CometChatMessageInformation` directly using `Navigator.push`, or you can define it as a widget within the `build` method of your `State` class.

##### 1. Using Navigator to Launch `CometChatMessageInformation`

<Tabs>
  <Tab title="Dart">
    ```dart theme={null}
    Navigator.push(context, MaterialPageRoute(builder: (context) => CometChatMessageInformation())); // Message object is required to launch this widget.
    ```
  </Tab>
</Tabs>

##### 2. Embedding `CometChatMessageInformation` as a Widget in the build Method

<Tabs>
  <Tab title="Dart">
    ```dart theme={null}
    import 'package:cometchat_chat_uikit/cometchat_chat_uikit.dart';
    import 'package:flutter/material.dart';

    class MessageInformation extends StatefulWidget {
      const MessageInformation({super.key});

      @override
      State<MessageInformation> createState() => _MessageInformationState();
    }

    class _MessageInformationState extends State<MessageInformation> {

      @override
      Widget build(BuildContext context) {
        return Scaffold(
            body: SafeArea(
                child: CometChatMessageInformation(message: baseMessage) // Message object is required to launch this widget.
            )
        );
      }
    }
    ```
  </Tab>
</Tabs>

### Actions

[Actions](/ui-kit/flutter/v4/components-overview#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.

##### 1. onClose

The `onClose` event is typically triggered when the back button is pressed and it carries a default action. However, with the following code snippet, you can effortlessly override this default operation.

<Tabs>
  <Tab title="Dart">
    ```dart theme={null}
    CometChatMessageInformation(
      message: baseMessage!,
      onClose: () {
        // TODO("Not yet implemented")
      },
    )
    ```
  </Tab>
</Tabs>

***

##### 2. onError

This action doesn't change the behavior of the widget but rather listens for any errors that occur in the MessageList widget.

<Tabs>
  <Tab title="Dart">
    ```dart theme={null}
    CometChatMessageInformation(
      message: baseMessage!,
      onError: (e) {
        // TODO("Not yet implemented")
      },
    )
    ```
  </Tab>
