whenOrNull<TResult extends Object?> method

  1. @optionalTypeArgs
TResult? whenOrNull<TResult extends Object?>(
  1. TResult? $default(
    1. String $type,
    2. int id,
    3. int reportId,
    4. @UReportActivityViewActivityConverter() UReportActivityViewActivity activity,
    5. String? internalNote,
    6. String? publicNote,
    7. Map<String, dynamic>? meta,
    8. bool isAutomated,
    9. String createdBy,
    10. @MemberConverter() Member? moderator,
    11. DateTime createdAt,
    12. Map<String, dynamic>? $unknown,
    )?
)

A variant of when that fallback to returning null

It is equivalent to doing:

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

Implementation

@optionalTypeArgs TResult? whenOrNull<TResult extends Object?>(TResult? Function( String $type,  int id,  int reportId, @UReportActivityViewActivityConverter()  UReportActivityViewActivity activity,  String? internalNote,  String? publicNote,  Map<String, dynamic>? meta,  bool isAutomated,  String createdBy, @MemberConverter()  Member? moderator,  DateTime createdAt,  Map<String, dynamic>? $unknown)?  $default,) {final _that = this;
switch (_that) {
case _ReportActivityView() when $default != null:
return $default(_that.$type,_that.id,_that.reportId,_that.activity,_that.internalNote,_that.publicNote,_that.meta,_that.isAutomated,_that.createdBy,_that.moderator,_that.createdAt,_that.$unknown);case _:
  return null;

}
