Two simple test files for dart.io.

1. Run dart download.dart
2. Run dart extract.dart

Have fun..

download.dart

import 'dart:io';

final metaPackageUrl =
    'https://storage.googleapis.com/pub-packages/packages/meta-1.1.7.tar.gz';

void main() async {
  final client = HttpClient();
  final req = await client.getUrl(Uri.parse(metaPackageUrl));
  final res = await req.close();
  print('status: ${res.statusCode}');
  final data = <int>[];
  await for (final chunk in res) {
    data.addAll(chunk);
  }
  await File('output.tar.gz').writeAsBytes(data);
}

extract.dart

import 'dart:io';

void main() async {
  await Directory('output').delete(recursive: true).catchError((_) {});
  await Directory('output').create();
  final p = await Process.start('tar', [
    '--extract',
    '--gunzip',
    '--no-same-owner',
    '--no-same-permissions',
    '--directory',
    'output',
  ]);
  await File('output.tar.gz').openRead().pipe(p.stdin);
  final exitcode = await p.exitCode;
  print('exitcode: $exitcode');
}
