whenOrNull<TResult extends Object?> method

@optionalTypeArgs TResult? whenOrNull<TResult extends Object?>(TResult? $default(UAdminUpdateSubjectStatusSubject subject, StatusAttr? takedown, StatusAttr? deactivated, 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(@UAdminUpdateSubjectStatusSubjectConverter()  UAdminUpdateSubjectStatusSubject subject, @StatusAttrConverter()  StatusAttr? takedown, @StatusAttrConverter()  StatusAttr? deactivated,  Map<String, dynamic>? $unknown)?  $default,) {final _that = this;
switch (_that) {
case _AdminUpdateSubjectStatusInput() when $default != null:
return $default(_that.subject,_that.takedown,_that.deactivated,_that.$unknown);case _:
  return null;

}
}
