maybeWhen<TResult extends Object?> method

  1. @optionalTypeArgs
TResult maybeWhen<TResult extends Object?>(
  1. TResult $default(
    1. String $type,
    2. String src,
    3. int id,
    4. String reasonType,
    5. String? reason,

    11. 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,  String src,  int id,  String reasonType,  String? reason, @UReportViewSubjectConverter()  UReportViewSubject subject,  Map<String, dynamic>? record, @ReportViewStatusConverter()  ReportViewStatus status, @JsonKey(toJson: iso8601)  DateTime createdAt, @JsonKey(toJson: iso8601)  DateTime updatedAt,  Map<String, dynamic>? $unknown)?  $default,{required TResult orElse(),}) {final _that = this;
switch (_that) {
case _ReportView() when $default != null:
return $default(_that.$type,_that.src,_that.id,_that.reasonType,_that.reason,_that.subject,_that.record,_that.status,_that.createdAt,_that.updatedAt,_that.$unknown);case _:
  return orElse();
