title: File_Picker plugin doesn't return absolute path for write file in Flutter
body: <p>I'm using the file_picker plugin to pick files from device storage in my flutter app. I need an absolute path so that I can read/write files. But picking file using file_picker plugin just returns the path of the copied file which is stored in the app cached (File loaded and cached at:/data/user/0/com.example.file_locker/cache/file_picker/Screenshot_2021-03-09-00-59-58-834_com.linkedin.android.jpg
  ).</p>
  <p>I'm using <strong>file_picker: ^2.1.6</strong>.</p>
  <p>file_picker repository issue <a href="https://github.com/miguelpruivo/flutter_file_picker/issues/40" rel="nofollow noreferrer">here</a>.</p>
  <p>Now, are there any solutions to get the absolute path from file_picker so that I can read/write the file?
  I'm stuck on my project, and your solutions will be appreciated.</p>
  <p>I've seen other file explorer plugin they also did the same way if you know some other else which return the desired solutions please let me know.</p>
  <p>Thank you in advance.</p>
