Implementation

@override
Future<void> run() async {
  final rest = argResults!.rest;
  if (rest.length > 1) {
    printErrorAndExit('--- Too many arguments specified ---');
  }
  final apiKey = Platform.environment['KENALL_API_KEY'];
  if (apiKey == null) {
    printErrorAndExit('--- KENALL_API_KEY is not found ---');
  }

  final postalCode = argResults!['code'] ?? '';
  if (postalCode.isEmpty) {
    printErrorAndExit('--- arguments postalCode is not found ---');
  }

  final config = Config(apiKey: apiKey!);
  final kenallClient = KenallClient(config, http.Client());
  try {
    final response = await kenallClient.getAddress(
      GetAddressRequest(postalCode: postalCode),
    );
    printInfo('version: ${response.version}');
    printInfo('city count: ${response.addresses.length}');
    response.addresses.forEach((address) {
      printInfo('address: ${address.toJson()}');
    });
    exit(0);
  } catch (error) {
