title: Directory not found in file explorer after being created using flutter code
body: <p>I created a directory using Flutter, to confirm the directory was created successfully I run the app for the second time and it shows the directory already exists,
  but I can't see the directory in the file browser.</p>
  
  <p>I also tried to create a text file in the directory, and
  tried to rename some photos to the directory </p>
  
  <p>The code I used to create the directory :</p>
  
  <pre><code>    Future createDir(String path) async
    {
  
      final dirName = new io.Directory(await getAppPath + "/Photo/Products");
      dirName.exists().then((isThere){
        isThere ? print("The Directory Exists Path is : " + dirName.path)
            : dirName.create(recursive: true).then((io.Directory directory){
          print("Create Directory Path is : " + directory.path);
        });
      });
    }
  
      Future&lt;String&gt; get getAppPath async
    {
      String resutl;
      io.Directory appDirectory = await getApplicationDocumentsDirectory();
      resutl = appDirectory.path;
      return resutl;
    }
  </code></pre>
  
  <p>Creating text file :</p>
  
  <pre><code>File saveTest = File(photoSavePaht + '/' + 'test.txt');
  print('Save Test path : ' + saveTest.path);
  saveTest.writeAsString('Test Text to save');
  </code></pre>
  
  <p>Renaming photo :</p>
  
  <pre><code>File movPhoto = File(savedPhoto);
  movPhoto.rename(_productImage.path);
  </code></pre>
  
  <p>I did not get any error message after running these code segments.</p>
