Implementation

Version? minAppVersion(Map response, {String tagName = 'mav'}) {
  Version? version;
  try {
    final desc = description(response);
    if (desc != null) {
      String regExpSource = r"\[\:tagName\:[\s]*(?<version>[^\s]+)[\s]*\]";
      regExpSource = regExpSource.replaceAll(RegExp('tagName'), tagName);
      final regExp = RegExp(regExpSource, caseSensitive: false);
      final match = regExp.firstMatch(desc);
      final mav = match?.namedGroup('version');

      if (mav != null) {
        try {
          // Verify version string using class Version
          version = Version.parse(mav);
        } on Exception catch (e) {
          if (debugLogging) {
            print(
                'upgrader: ITunesResults.minAppVersion: $tagName error: $e');
          }
        }
      }
    }
  } on Exception catch (e) {
    if (debugLogging) {
      print('upgrader.ITunesResults.minAppVersion : $e');
    }
  }
  return version;
