when<TResult extends Object?> method

@optionalTypeArgs TResult when<TResult extends Object?>(TResult $default(bool showErrorMsg, String loadingText, String? contentType, Map<String, dynamic> headers, bool showDefaultLoading, @JsonKey.new(name: 'data', toJson: _dataToJson) dynamic data, ResponseType? responseType, bool? nullParams, @igFreezedJson RequestEncoder? requestEncoder, @igFreezedJson DioStart? dioStart, bool? returnIsString, @igFreezedJson String? fullUrl, @igFreezedJson InterceptorCall? interceptorCall, @igFreezedJson UrlParseFormat? urlParseFormat, @igFreezedJson ResponseResultCallback? responseResultCallback, Map<String, dynamic>? extra, @igFreezedJson CancelToken? cancelToken, @igFreezedJson ProgressCallback? onSendCallback, @igFreezedJson ProgressCallback? onReceiveProgress, String? downloadUrl, @igFreezedJson File? savePath,))

A switch-like method, using callbacks.

As opposed to map, this offers destructuring. It is equivalent to doing:

switch (sealedClass) {
  case Subclass(:final field):
    return ...;
  case Subclass2(:final field2):
    return ...;
}
