ListOperation<T> class sealed

Describes an operation on a cached list.

Provides built-in operations for common list mutations with type safety.

Example:

// Append an item
final op = ListOperation.append(newItem);

// Update items matching a condition
final op = ListOperation.updateWhere(
  (item) => item.id == targetId,
  (item) => item.copyWith(name: 'New Name'),
);

// Remove items matching a condition
final op = ListOperation.removeWhere((item) => item.id == targetId);
