maybeWhen<TResult extends Object?> method

  1. @optionalTypeArgs
TResult maybeWhen<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,
    )?, {
  2. required TResult orElse(),
})

A variant of when that fallback to an orElse callback.

It is equivalent to doing:

switch (sealedClass) {
  case Subclass(:final field):
    return ...;
  case _:
    return orElse();
}

Implementation

@optionalTypeArgs TResult maybeWhen<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,{required TResult orElse(),}) {final _that = this;
switch (_that) {
case _LabelerServiceRecord() when $default != null:
return $default(_that.$type,_that.policies,_that.labels,_that.createdAt,_that.reasonTypes,_that.subjectTypes,_that.subjectCollections,_that.$unknown);case _:
  return orElse();

}
