Where are the plugins when you install w flatpak?

[lac]

I think this is an installation question.  If instead you think it makes more sense as a plugin question, feel free to move this.

I needed to manipulate images, add layers to them, remove artifacts, etc.  I have used gimp before on debian linux, and there were
debian packages that handled the python-fu and other plugins.  But apparently all of that isn't being supported now by debian.  Since I knew
that using resythesizer was going to be a significant part of the job, I went to https://github.com/bootchk/resynthesizer...ynthesizer where it suggested that I install a flatpak verison of gimp 3.2 and then resythesizer for flatpak.  This seemed ok to me.

The command I used to install resythesizer was:
 flatpak install org.gimp.GIMP.Plugin.Resynthesizer org.gimp.GIMP.Plugin.LiquidRescale org.gimp.GIMP.Plugin.Lensfun org.gimp.GIMP.Plugin.GMic org.gimp.GIMP.Plugin.Fourier org.gimp.GIMP.Plugin.FocusBlur org.gimp.GIMP.Plugin.BIMP

This worked fine.  gimp 3.2 was fine.  resynthesizer worked fine.  Weeks passed.  Many .xcf files were created.  And then I found out that while some of our users want the art precisely as we have created it, a different set want the same art with a larger canvas -- the whole think shifted 8 transparent pixels to the right and 44 transparent pixels down.  This seems to be a straight-forward job for a python plugin.  I've never made one but I do know how to program in python, so I figured that this would be ok.  The first thing I wanted to do was look at existing plugins to see how they worked.  And unfortunately, I could not find any.

The flatpak installation document mentioned "Note: if you install through flatpak, it may be necessary to point GIMP to the newly installed plugins locations, so it knows where to load them from. In GIMP: Edit - Preferences - Folders - Plugins and use a plus sign to add plugin folders of newly installed flatpaks."  But Edit - Preferences - Folders  is empty. Not only are there no Plug-ins, but also no Brushes, Palettes, Patterns etc either.  "Temporary Folder" and "Swap Folder" are the only things mentioned.  So no "adding plus signs" is possible.

....  I decided to experiment.  I made a file batch_add_borders.py and installed it in
/home/lac/.config/GIMP/3.2/plug-ins/ which is also empty.

Now when gimp starts it reports:
Skipping potential plug-in '/home/lac/.config/GIMP/3.2/plug-ins/batch_add_borders.py': plug-ins must be installed in subdirectories.

I don't know what this means; I thought I did exactly that by adding it to the plugins directory.

Can somebody explain what I should do now?

Thank you.

First, your flatpak installation.  You seem to have a lot of old, possibly redundant installations there.
(1) is a typical installation, a Gimp 3.2.x and flatpak plugins that are version 3.  

(2) In Gimp Edit -> Preferences -> Folders (click to expand) -> Plug-ins  it shows the paths to the plugin folders.  You have found the only one you need ~/.config/GIMP/3.2/plug-ins

About Gimp 3 plugins.  They can be binary like resynthesizer or python or script-fu  What ever type, they go in a folder with the same name as the plugin.  So batch_add_borders.py  goes in its own folder batch_add_borders without any extension and for linux the plugin has to be executable.
As examples (3) is the Batcher python plugin, complicated comes with lots of dependencies. (4) A simple script-fu plugin  but still has to go in its own folder.
