SteamDeck - No .stfolder when creating folders with in ~/.var

The solution is;

  1. Open Discover and Install Flatseal by searching for flatseal in the search box
  2. Once installed, launch flatseal
  3. On the left scroll down until you find “Syncthing GTK” and click on that.
  4. On the right scroll down to the “Filesystem” section
  5. In Other Files click the button on the right with a picture of a folder with a + plus sign
  6. Type ~/.var/app:rw
  7. Close flatseal and restart the Steam Deck (or find a way to restart sync thing, I tried via the web interface and systemctl, and nothing changed but restarting the Steam Deck worked the best).

Then it should work to sync folders inside of ~/.var/app.
