title: Cannot find the path provided by getApplicationDocumentsDirectory()
body: <p>I tested this flutter app example:
  <a href="https://github.com/tensor-programming/flutter_read_write_file_and_path" rel="noreferrer">https://github.com/tensor-programming/flutter_read_write_file_and_path</a></p>
  
  <p>But, browsing my device with a file-manager (Solid Explorer), I cannot find the file "db.txt" created by this example.</p>
  
  <pre><code>final path = await localPath;
  </code></pre>
  
  <p>I checked in many folders including:</p>
  
  <ul>
  <li>/storage/emulated/0 (= sdcard)</li>
  <li>sdcard/Android/data</li>
  <li>sdcard/data</li>
  </ul>
  
  <p>Where is this file?
  Should I root my device to find/see it?</p>
  
  <p>What string to add after the "path" variable to reach the Download folder?
  Or, how to get the absolute path to the Download folder?</p>
  
  <p>Device: GALAXY S8+ SM-G955F. Android 8.0. Not Rooted.
  Flutter beta v0.5.1. Dart 2.0.0-dev.58.0. Windows 10.
  Thanks and regards</p>
