whenOrNull<TResult extends Object?> method

  1. @optionalTypeArgs
TResult? whenOrNull<TResult extends Object?>(
  1. TResult? $default(
    1. UAdminGetSubjectStatusSubject subject,
    2. StatusAttr? takedown,
    3. StatusAttr? deactivated,
    4. 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(@UAdminGetSubjectStatusSubjectConverter()  UAdminGetSubjectStatusSubject subject, @StatusAttrConverter()  StatusAttr? takedown, @StatusAttrConverter()  StatusAttr? deactivated,  Map<String, dynamic>? $unknown)?  $default,) {final _that = this;
switch (_that) {
case _AdminGetSubjectStatusOutput() when $default != null:
return $default(_that.subject,_that.takedown,_that.deactivated,_that.$unknown);case _:
  return null;

}
}
