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('qa_data/zips/EC16100.zip');
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  // Get the 1st file in the .zip
  final entry = CkZipEntry();
  try {
    zip.entryAt(0, entry);
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  final fileContents = entry.unzipToString(0, 'utf-8');
  print(fileContents);
