when<TResult extends Object?> method

@optionalTypeArgs TResult when<TResult extends Object?>(TResult $default(@JsonKey.new(name: 'id') int id, @JsonKey.new(name: 'account_id') int accountId, @JsonKey.new(name: 'address') String address, @JsonKey.new(name: 'city') String city, @JsonKey.new(name: 'zip_code') String zipCode, @JsonKey.new(name: 'province') String province, @JsonKey.new(name: 'country') String country, @JsonKey.new(name: 'tax_code') String? taxCode, @JsonKey.new(name: 'vat_number') String? vatNumber, @JsonKey.new(name: 'business_name') String? businessName, @JsonKey.new(name: 'deleted_at') DateTime? deletedAt, @JsonKey.new(name: 'created_at') DateTime? createdAt, @JsonKey.new(name: 'updated_at') 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 ...;
}
