ContentItem class abstract

The base class for all content items in Vyuh.

A content item represents a piece of content that can be:

• Fetched from a Content Management System (CMS)
• Rendered on screen with a specific layout
• Modified with content modifiers
• Organized in a content hierarchy

Content items are the building blocks of a Vyuh application's content. They combine data from the CMS with presentation logic to create rich, interactive user interfaces.

Example:

@JsonSerializable()
class BlogPost extends ContentItem {
  static const schemaName = 'blog.post';

  final String title;
  final String content;

  BlogPost({
    required this.title,
    required this.content,
    super.layout,
    super.modifiers,
  }) : super(schemaType: schemaName);
}
