      if (regExp.hasMatch(userAgent)) {
        Iterable<RegExpMatch> matches = regExp.allMatches(userAgent);
        String unformattedName =
            matches.first.namedGroup('unformattedName') ??
                engineParser.name.toLowerCase();
        String version = matches.first.namedGroup('version') ?? '';

        return Engine(
          name: engineParser.name,
          unformattedName: unformattedName,
          version: version,
