See more Zip Examples

Demonstrates how to iterate over the files contained within a .zip and unzip specific files. Dart

import 'package:chilkat/chilkat.dart';

void main() {
  // This example requires the Chilkat API to have been previously unlocked.
  // See Global Unlock Sample for sample code.

  final zip = CkZip();

  try {
    zip.openZip('my_files.zip');
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  final unzipDir = '/temp/unzipDir';

  // Get the number of files and directories in the .zip
  final n = zip.numEntries;

  final entry = CkZipEntry();

  var i = 0;
  while (i < n) {

    zip.entryAt(i, entry);
    if (!entry.isDirectory) {
      // (the filename may include a path)
      print(entry.fileName);

      // Your application may choose to unzip this entry
      // based on the filename.
      // If the entry should be unzipped, then call Extract(unzipDir)
      try {
        entry.extract(unzipDir);
      } on ChilkatException catch (e) {
        print(e.lastErrorText);
        return;
      }
    }

    i++;
  }
