Add support for Embedded Objects

[ibrahim-mubarak]

Describe the solution you'd like

@Entity()
class User {
  User(this.id, this.address);

 @Id
  final int id;

 @Embedded()
  final Address? address;
}

class Address {
 final String? streetAddress1;
 final String? streetAddress2
}

Database schema for User then becomes

id
street_address_1
street_address_2

Describe alternatives you've considered

The alternatives are as mentioned in objectbox/objectbox-java#456

Thanks for your request! For anyone else interested, please thumbs up the first post!

As noted objectbox/objectbox-java#456 is the Java issue about this.

And the current workarounds are to

• serialize objects (e.g. to a JSON string) or,
• use a to-one relation.
