whenOrNull<TResult extends Object?> method

@optionalTypeArgs TResult? whenOrNull<TResult extends Object?>(TResult? $default(String version, BuildProcessingState processingState, String? uploadedDate, @JsonKey.new(name: 'expired') bool isExpired, @JsonKey.new(name: 'usesNonExemptEncryption') bool? doesUseNonExemptEncryption,)?)

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 version,  BuildProcessingState processingState,  String? uploadedDate, @JsonKey(name: 'expired')  bool isExpired, @JsonKey(name: 'usesNonExemptEncryption')  bool? doesUseNonExemptEncryption)?  $default,) {final _that = this;
switch (_that) {
case _BuildAttributesDto() when $default != null:
return $default(_that.version,_that.processingState,_that.uploadedDate,_that.isExpired,_that.doesUseNonExemptEncryption);case _:
  return null;

}
}
