List operators in group channel

An operator list is a complete list of operators of a group channel. The operator list is created through GroupChannelOperatorsFragment.

You can start building an operator list screen by first creating a fragment. To do so, call the createGroupChannelOperatorsFragment method. Once an operator list fragment is built, you need to set up the navigation props and register the screen to a navigation library. Refer to the code below.

import React from 'react';

import { useGroupChannel } from '@sendbird/uikit-chat-hooks';
import { createGroupChannelOperatorsFragment, useSendbirdChat } from '@sendbird/uikit-react-native';

const GroupChannelOperatorsFragment = createGroupChannelOperatorsFragment();
const GroupChannelOperatorsScreen = ({ route: { params } }: any) => {
    const { sdk } = useSendbirdChat();
    const { channel } = useGroupChannel(sdk, params.channelUrl);
    if (!channel) return null;
    
    const navigateToBack = () => {};
    const navigateToGroupChannelRegisterOperator = () => {};
    
    return (
        <GroupChannelOperatorsFragment
            channel={channel}
            onPressHeaderLeft={navigateToBack}
            onPressHeaderRight={navigateToGroupChannelRegisterOperator}
        />
    );
};

The following table lists the properties of GroupChannelOperatorsFragment.

To store and handle data that are used to build the operator list screen, Sendbird UIKit provides GroupChannelOperatorsContexts, which includes the Fragment context object.

type GroupChannelOperatorsContextsType = {
    Fragment: React.Context<{
        headerTitle: string;
        channel: Sendbird.GroupChannel;
    }>;
};

To retrieve data from the Chat SDK on the current user's operator list screen, you need to call the useContext hook and pass GroupChannelOperatorsContexts.Fragment as a parameter. The data is then used to render the operator list module and its components.

const Component = () => {
    const {
        headerTitle,
        channel,
    } = useContext(GroupChannelOperatorsContexts.Fragment);
};

An operator list screen is composed of five module components: header, list, loading status, loading error, and empty status. These components make up the GroupChannelOperatorsModule and are used to create and display the UI of the screen.

The header component displays the title of the group channel, a button on the top left corner, and another button on the top right corner. By default, the left button allows you to go back to the previous screen and when selected, the onPressHeaderLeft navigation prop is called. When the right button is selected, onPressHeaderRight is called and the group channel settings screen appears.

The following table lists the properties of GroupChannelOperatorsModule.Header.

The list component shows a list of profile images and names of operators of the channel.

The following table lists the properties of GroupChannelOperatorsModule.List.

The StatusLoading component lets the user know if the list is loading.

The StatusEmpty component lets the user know if the list is empty.

The StatusError component lets the user know if the list fetching has failed.

In the list operators in group channel key function, you can customize the default GroupChannelOperatorsFragment to change various elements of the screen such as the module and its components. See the code below on how to replace the default header component with a custom header component in GroupChannelOperatorsFragment as an example.

Note: To learn more about how to customize a fragment, go to the Fragment page.

const GroupChannelOperatorsFragment = createGroupChannelOperatorsFragment({
    Header: () => <MyHeader />, // Use custom header
});
const GroupChannelOperatorsScreen = ({ route: { params } }: any) => {
    const { sdk } = useSendbirdChat();
    const { channel } = useGroupChannel(sdk, params.channelUrl);
    if (!channel) return null;
    
    const navigateToBack = () => {};
    const navigateToGroupChannelRegisterOperator = () => {};
    
    return (
        <GroupChannelOperatorsFragment
            channel={channel}
            onPressHeaderLeft={navigateToBack}
            onPressHeaderRight={navigateToGroupChannelRegisterOperator}
        />
    );
};
