title: Do not display notification if download failed using flutter_downloader package in flutter
body: <p>In my app i have download functionality and i used flutter_downloader package to download file.</p>
  <p>Below is function for download file.</p>
  <pre><code>static Future&lt;String?&gt; downloadPdf(String path, String downloadLink) async {
      final taskId = await FlutterDownloader.enqueue(
        url: downloadLink,
        savedDir: path,
        showNotification: true,
        openFileFromNotification: true,
        saveInPublicStorage: true,
      );
  
      return taskId;
