This single-block plugin allows you to display a meta field or a custom field as a block on the front end. It supports custom fields for posts, terms, and users. It can be nested inside a parent block that has postId and postType context, such as Query Block, WooCommerce Product Collection, or used as a stand-alone block. You can display any field whose value can be retrieved by the core API (get_post_meta, get_term_meta, get_user_meta) and is a string or can be converted to a string.
