Returns whether the candidate version/build is strictly newer.

Implementation

  required String candidateVersion,
  required int candidateBuildNumber,
  required String currentVersion,
  required String currentBuildNumber,

    throw FormatException(
      'Invalid current build number: $currentBuildNumber',
    );
  }

  final versionComparison = compare(candidateVersion, currentVersion);
  if (versionComparison != 0) return versionComparison > 0;
  return candidateBuildNumber > parsedCurrentBuild;
