Tag class abstract

Abstract base class for creating and manipulating HTML elements programmatically. Tag provides a foundation for building HTML structures in Dart code with support for attributes, child elements, CSS classes, and inline styles. It offers a fluent API for chaining operations and maintains the hierarchical structure of HTML documents. Key features:

• Dynamic attribute management
• CSS class manipulation
• Inline style handling
• Child element management
• HTML string generation
• Fluent method chaining Example usage:

final div = CustomTag('div')
  .addClass('container')
  .addAttr('data-id', '123')
  .addStyle('background-color', 'blue')
  .addChild(CustomTag('p').addChild(TextTag('Hello World')));
String html = div.toHtml();
// Result: <div class="container" data-id="123" style="background-color: blue; "><p>Hello World</p></div>
