Directory extractTarFiles(String inputPath, String outputPath)

Extract the entries in the given tar file to a directory.

Implementation

    final tarOutput = OutputFileStream(tarPath);
    GZipDecoder().decodeStream(input, tarOutput);
    input.closeSync();
    tarOutput.closeSync();
  }

  final outDir = Directory(outputPath);

    outDir.createSync(recursive: true);
  }
