The easiest solution will be to mount the partitions of interest
somewhere before examining them with the appropriate tools.

If you are interested in how gparted works, perhaps you might
review your previous question on this topic:
   https://lists.debian.org/debian-user/2019/01/msg00910.html

In particular:
   https://lists.debian.org/debian-user/2019/01/msg01106.html
   https://lists.debian.org/debian-user/2019/01/msg01112.html
shows that gparted was using dumpe2fs.

You can run that tool yourself. Maybe something like:
# dumpe2fs -h /dev/sda1 | grep ^Free
