Option<T extends UIPayload> class abstract mixin

Interface for selectable options in dropdowns, radio buttons, etc.

Implement this on your enum or class to make it usable in option-based form inputs. The title provides the display text for the UI.

Example with enum:

enum Priority with Option<UIText> {
  low, medium, high;

  @override
  UIText get title => switch (this) {
    Priority.low => SimpleText('Low'),
    Priority.medium => SimpleText('Medium'),
    Priority.high => SimpleText('High'),
  };
}

Example with class:

class Country with Option<UIText> {
  final String code;
  final String name;

  @override
  UIText get title => SimpleText(name);
}
