AggregateRoot<TId extends Id> class abstract

Represents the root of an aggregate, a cluster of domain entities and value objects.

This abstract class extends Entity, inheriting its identity characteristics, and serves as the foundation for all aggregate roots in the domain model. Aggregate roots are the main entry points for accessing and performing operations on aggregates, ensuring consistency and enforcing aggregate boundaries.

The generic type parameter TId represents the type of the identifier used by the aggregate root, which must extend from Id. This allows for flexibility in defining custom identifier types for different aggregates.

Usage:

class User extends AggregateRoot<UserId> {
  final String name;

  User({required UserId id, required this.name}) : super(id: id);
}
