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>
