It shows the list of messages of the current channel.

class ChannelPage extends StatelessWidget {
  const ChannelPage({
    Key key,
  }) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: ChannelHeader(),
      body: Column(
        children: <Widget>[
          Expanded(
            child: MessageListView(
              threadBuilder: (_, parentMessage) {
                return ThreadPage(
                  parent: parentMessage,
                );
              },
            ),
          ),
          MessageInput(),
        ],
      ),
    );
  }
}

Make sure to have a StreamChannel ancestor in order to provide the information about the channels. The widget uses a ListView.custom to render the list of channels.

The widget components render the ui based on the first ancestor of type StreamChatTheme. Modify it to change the widget appearance.
