when<TResult extends Object?> method

  1. @optionalTypeArgs
TResult when<TResult extends Object?>(
  1. TResult $default(
    1. String $type,
    2. LabelerPolicies policies,
    3. ULabelerServiceLabels? labels,
    4. DateTime createdAt,
    5. List<ReasonType>? reasonTypes,
    6. List<SubjectType>? subjectTypes,
    7. List<String>? subjectCollections,
    8. Map<String, dynamic>? $unknown,
    )
)

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 ...;
}

Implementation

@optionalTypeArgs TResult when<TResult extends Object?>(TResult Function( String $type, @LabelerPoliciesConverter()  LabelerPolicies policies, @ULabelerServiceLabelsConverter()  ULabelerServiceLabels? labels,  DateTime createdAt, @ReasonTypeConverter()  List<ReasonType>? reasonTypes, @SubjectTypeConverter()  List<SubjectType>? subjectTypes,  List<String>? subjectCollections,  Map<String, dynamic>? $unknown)  $default,) {final _that = this;
switch (_that) {
case _LabelerServiceRecord():
return $default(_that.$type,_that.policies,_that.labels,_that.createdAt,_that.reasonTypes,_that.subjectTypes,_that.subjectCollections,_that.$unknown);case _:
  throw StateError('Unexpected subclass');

}
