when<TResult extends Object?> method

@optionalTypeArgs TResult when<TResult extends Object?>({ required TResult cancel(@igFreezedJson Object? error, @igFreezedJson RequestOptions? options), required TResult connectionTimeout(), required TResult sendTimeout(), required TResult receiveTimeout(), required TResult badCertificate(), required TResult connectionError(), required TResult badResponse(@igFreezedJson Response? response, int? statusCode), required TResult businessException(String message, @igFreezedJson Object? error, @igFreezedJson StackTrace? stackTrace), })

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 ...;
}

Implementation

@optionalTypeArgs
TResult when<TResult extends Object?>({
  required TResult Function(@igFreezedJson Object? error,
          @igFreezedJson RequestOptions? options)
      cancel,
  required TResult Function() connectionTimeout,
  required TResult Function() sendTimeout,
  required TResult Function() receiveTimeout,
  required TResult Function() badCertificate,
  required TResult Function() connectionError,
  required TResult Function(
          @igFreezedJson Response? response, int? statusCode)
      badResponse,
  required TResult Function(String message, @igFreezedJson Object? error,
          @igFreezedJson StackTrace? stackTrace)
      businessException,
}) {
  final _that = this;
  switch (_that) {
    case BaseApiCancelException():
      return cancel(_that.error, _that.options);
    case BaseApiConnectionTimeoutException():
      return connectionTimeout();
    case BaseApiSendTimeoutException():
      return sendTimeout();
    case BaseApiReceiveTimeoutException():
      return receiveTimeout();
    case BaseApiBadCertificateException():
      return badCertificate();
    case BaseApiConnectionErrorException():
      return connectionError();
    case BaseApiBadResponseException():
      return badResponse(_that.response, _that.statusCode);
    case BaseApiBusinessException():
      return businessException(_that.message, _that.error, _that.stackTrace);
  }
