Add filter to FileDialog Lbrary entry

[sonnyp]

We should demonstrate the usage of filter in the Open File library entry

  text_files = gtk_file_filter_new ();
  gtk_file_filter_set_name (text_files, _("Text Files"));
  gtk_file_filter_add_mime_type (text_files, "text/plain");
  gtk_file_filter_add_mime_type (text_files, "application/x-zerosize");
  gtk_file_chooser_add_filter (GTK_FILE_CHOOSER (native), g_object_ref (text_files));

Hi @sonnyp I would like to work on this issue. If you could assign me to it an provide an additional context you have that would be great.

[sonnyp]

In Workbench Library, there is a entry named ""Open File"

We should demonstrate the usage of filters so that only one type of file can be selected.

HEre is an example

  const filter = Gtk.FileFilter.new();
  filter.set_name("Text Files");
  filter.add_mime_type("text/*");
  const filters = new Gio.ListStore();
  filters.append(filter);

  const file_dialog = new Gtk.FileDialog({ filters });

Hey @sonnyp can you tell me the expected behavior of Open File cause it is showing error when i select open file

and open multiple files just logs the number of file selected .

[sonnyp]

ha yes - I'm aware of this bug might be a good idea to fix it first

The problem is that in the Flatpak sandbox GLib.get_user_special_dir(GLib.UserDirectory.DIRECTORY_DOWNLOAD) returns NULL

If you like you can send a PR that removes initial_folder and default_dir

Removed initial_folder and default_folder. https://gist.github.com/Sahil-Shadwal/6d63af8c237bf069e4ed7af7026a5790

So, should i make PR first and get my code reviewed or after ?
