## Overview

`CometChatGroups` functions as a standalone [Widget](/ui-kit/flutter/v4/components-overview#components) designed to create a screen displaying a list of groups, with the added functionality of enabling users to search for specific groups. Acting as a container widget, `CometChatGroups` encapsulates and formats the `CometChatListBase` and `CometChatGroupList` widgets without introducing any additional behavior of its own.

| [CometChatListBase](/ui-kit/flutter/v4/list-base) | `CometChatListBase` serves as a container widget equipped with a title (navigationBar), search functionality (search-bar), background settings, and a container for embedding a list view. |
| [CometChatListItem](/ui-kit/flutter/v4/list-item) | This widget renders information extracted from a `Group` object onto a tile, featuring a title, subtitle, leading view, and trailing view.                                                 |

## Usage

### Integration

As `CometChatGroups` is a custom **widget**, it can be launched directly by user actions such as button clicks or other interactions.

You can launch `CometChatGroups` 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 `CometChatGroups`

<Tabs>
  <Tab title="Dart">
    ```dart theme={null}
    Navigator.push(context, MaterialPageRoute(builder: (context) => const CometChatGroups()));
    ```
  </Tab>
</Tabs>

##### 2. Embedding `CometChatGroups` 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 Groups extends StatefulWidget {
      const Groups({super.key});

      @override
      State<Groups> createState() => _GroupsState();
    }

    class _GroupsState extends State<Groups> {

      @override
      Widget build(BuildContext context) {
        return const Scaffold(
            body: SafeArea(
                child: CometChatGroups()
            )
        );
      }
    }
    ```
  </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. onItemTap

This method proves valuable when users seek to override onItemTap functionality within CometChatGroups, empowering them with greater control and customization options.

The `onItemTap` action doesn't have a predefined behavior. You can override this action using the following code snippet.

<Tabs>
  <Tab title="Dart">
    ```dart theme={null}
    CometChatGroups(
      onItemTap: (context, group) {
        // TODO("Not yet implemented")
      },
    )
    ```
  </Tab>
</Tabs>

***

##### 2. onBack

Enhance your application's functionality by leveraging the `onBack` feature. This capability allows you to customize the behavior associated with navigating back within your app. Utilize the provided code snippet to override default behaviors and tailor the user experience according to your specific requirements.

<Tabs>
  <Tab title="Dart">
    ```dart theme={null}
    CometChatGroups(
      onBack: () {
        // TODO("Not yet implemented")
      },
    )
    ```
  </Tab>
</Tabs>

***

##### 3. onError

You can customize this behavior by using the provided code snippet to override the `onError` and improve error handling.

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

***

##### 4. onItemLongPress

This method becomes invaluable when users seek to override long-click functionality within CometChatGroups, offering them enhanced control and flexibility in their interactions.

The `onItemLongPress` action doesn't have a predefined behavior. You can override this action using the following code snippet.

<Tabs>
  <Tab title="Dart">
    ```dart theme={null}
    CometChatGroups(
      onItemLongPress: (context, group) {
        // TODO("Not yet implemented")
      },
    )
    ```
  </Tab>
</Tabs>

***

##### 5. onSelection

When the `onSelection` event is triggered, it furnishes the list of selected groups. This event can be invoked by any button or action within the interface. You have the flexibility to implement custom actions or behaviors based on the selected groups.

This action does not come with any predefined behavior. However, you have the flexibility to override this event and tailor it to suit your needs using the following code snippet.

<Tabs>
  <Tab title="Dart">
    ```dart theme={null}
    CometChatGroups(
      selectionMode: SelectionMode.multiple,
      activateSelection: ActivateSelection.onClick,
      onSelection: (groupList) {
        // TODO("Not yet implemented")
      }
    )
    ```
  </Tab>
</Tabs>

***

### Filters

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

##### 1. GroupsRequestBuilder

The [GroupsRequestBuilder](/sdk/flutter/retrieve-groups) enables you to filter and customize the group list based on available parameters in GroupsRequestBuilder. This feature allows you to create more specific and targeted queries when fetching groups. The following are the parameters available in [GroupsRequestBuilder](/sdk/flutter/retrieve-groups)

<Tabs>
  <Tab title="Dart">
    ```dart theme={null}
    CometChatGroups(
        groupsRequestBuilder: GroupsRequestBuilder()
            ..limit = 10
    )
    ```
  </Tab>
</Tabs>
