Choice class - multi_select library

Choice<T> class

Represents a selectable choice item.

The key field serves dual purposes:

Unique identification for validation and selection tracking
Grouping: if key is null or empty, the choice acts as a group title

Example:

List<Choice<Car>> choices = [
  Choice(null, 'Sports Cars'),  // Group title
  Choice('1', 'Ferrari', metadata: Car(...)),
  Choice('2', 'Porsche', metadata: Car(...)),
  Choice(null, 'SUVs'),  // Another group title
  Choice('3', 'Range Rover', metadata: Car(...)),
];
