EasyAttribute<T extends Object?> class abstract

The base class for all text attributes in the EasyText system.

EasyAttribute represents a styling or formatting property that can be applied to text content. Attributes can be either inline (applied to specific text ranges) or block-level (applied to entire paragraphs or blocks).

Attribute Types:

Inline Attributes: Applied to text selections (color, bold, italic, etc.)
Block Attributes: Applied to entire paragraphs (alignment, indentation, etc.)
Exclusive Attributes: Cannot be combined with other exclusive attributes

Usage Example:

// Create custom attribute
class CustomAttr extends EasyAttribute<String> {
  CustomAttr(String value) : super(value: value);

  @override
  String get key => 'custom';

  @override
  bool get isInline => true;

  @override
  bool get exclusive => false;

  @override
  bool canMergeWith(EasyAttribute attribute) => true;

  @override
  EasyAttribute clone(String value) => CustomAttr(value);
}
