Unzip Files to Byte Array

See more Zip Examples

Demonstrates how to unzip each file contained in a .zip to an in-memory byte array. Dart

import 'package:chilkat/chilkat.dart';

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

  final zip = CkZip();

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

  // Iterate of each entry in the zip.
  // An entry can be a file or directory entry.  For each file, unzip to a byte array.
  final numEntries = zip.numEntries;
  print('NumEntries = $numEntries');

  final entry = CkZipEntry();
  var i = 0;
  while (i < numEntries) {
    zip.entryAt(i, entry);
    if (!entry.isDirectory) {
      final fileData = entry.inflate();
      // Do whatever you wish with the file data...
    }

    i++;
  }

  zip.closeZip();

  print('Finished.');
