      return PackageVersionNumberGeneralLibraryRange(
          min: other.min,
          max: other.max,
          includeMin: true,
          includeMax: other.includeMax,
          alwaysIncludeMaxPreRelease: true);
    }

    if (other.max == this) {
      return PackageVersionNumberGeneralLibraryRange(
          min: other.min,
