import 'package:chilkat/chilkat.dart';

void main() {
  var success = false;

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

  final zip = CkZip();

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

  final entry = CkZipEntry();

  success = zip.entryOf('hamlet.xml', entry);
  if (!success) {
    print(zip.lastErrorText);
    return;
  }

  entry.fileName = 'hamlet2.xml';

  success = zip.entryOf('helloWorld.pl', entry);
  if (!success) {
    print(zip.lastErrorText);
    return;
  }

  entry.fileName = 'hw.pl';

  // Now unzip to the "test" subdirectory, under our current
  // working directory:
  final numFilesUnzipped = zip.unzip('test');
  if (numFilesUnzipped < 0) {
    print(zip.lastErrorText);
    return;
  }

  // The filenames within the .zip are unchanged, but it unzipped
  // test/hw.pl and test/hamlet2.xml
