when<TResult extends Object?> method

  1. @optionalTypeArgs
TResult when<TResult extends Object?>(
  1. TResult $default(
    1. int id,
    2. int accountId,
    3. String address,
    4. String city,
    5. String zipCode,
    6. String province,
    7. String country,

    9. String? vatNumber,
    10. String? businessName,
    11. DateTime? deletedAt,
    12. DateTime? createdAt,
    13. DateTime? updatedAt,
    )
)

A switch-like method, using callbacks.

As opposed to map, this offers destructuring. It is equivalent to doing:

switch (sealedClass) {
  case Subclass(:final field):
    return ...;
  case Subclass2(:final field2):
    return ...;
}
