    print("Media tapped");
  },
  style: LMFeedPostMediaStyle(
    videoStyle: LMFeedPostVideoStyle(

In this example, an LMFeedPostMedia widget is created with a postId and a list of attachments. The title and subtitle properties are used to provide additional information about the media section. The onError and onMediaTap callbacks are used to handle errors and media tap events, respectively. The style property is used to customize the appearance of different types of media attachments using the LMFeedPostMediaStyle class.
