      appBar: ChannelHeader(),
      body: Column(
        children: <Widget>[
          Expanded(
            child: MessageListView(
              threadBuilder: (_, parentMessage) {
                return ThreadPage(
                  parent: parentMessage,
                );
              },
            ),
          ),
          MessageInput(),

      ),
    );
  }
}

You usually put this widget in the same page of a MessageListView as the bottom widget.

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