> PSA: I have no idea what im doing

I know Omarchy is opinionated and not sure how it feels about flatpaks, but for people like me who prefer flatpaks when possible, I added it to the walker menu.

If this is going to be considered for addition to omarchy, obviously either flatpak will need to be preinstalled (which people might not like) or the menu will need to dynamically populate based on whether or not flatpak is installed or not.

_or either prompt the user to install it first, or install it for them.. Personally think these are jank_ 

__Prerequisites:__
- install flatpak with `install > package > flatpak` from omarchy menu

---

updated the following functions (_"others" is existing code_)
> before updating the function, copy the file from the `~/.local/share/omarchy/bin` and place it in `~/.local/bin`

`file: /omarchy-menu`
```bash
show_install_menu() {
  case $(menu "...others \n Flatpak") in
  ... others
  *Flatpak*) terminal omarchy-flatpak-install ;;
  esac
}

show_remove_menu() {
  case $(menu "...others \n Flatpak") in
  ...others 
  *Flatpak*) terminal omarchy-flatpak-remove ;;
  esac
}
```

---

And added the following shell scripts:
> place these in `~/.local/bin`

`file: /omarchy-flatpak-remove`
```bash
#!/bin/bash

# some flatpak app names are space seperated and thus we need to traverse until we find
# the id of the flatpak which must contain a minimum of 2 dots
extract_dotted() {
    awk '{
        for (i = 1; i <= NF; i++) {
            if (gsub(/\./, "&", $i) >= 2) {
                print $i
            }
        }
    }'
}

fzf_args=(
  --multi
  --preview 'flatpak info $(echo {} | awk "{for (i = 1; i <= NF; i++) { if (gsub(/\\./, \"&\", \$i) >= 2) { print \$i; exit } }}")' # redudant reuse of extract_dotted func. Could abstract to util bin
  --preview-label='alt-p: toggle description, alt-j/k: scroll, tab: multi-select, F11: maximize'
  --preview-label-pos='bottom'
  --preview-window 'down:65%:wrap'
  --bind 'alt-p:toggle-preview'
  --bind 'alt-d:preview-half-page-down,alt-u:preview-half-page-up'
  --bind 'alt-k:preview-up,alt-j:preview-down'
  --color 'pointer:red,marker:red'
)

pkg_names=$(flatpak list --app | fzf "${fzf_args[@]}")

if [[ -n "$pkg_names" ]]; then
  val=$(echo "$pkg_names" | extract_dotted)
  echo "$pkg_names" | extract_dotted | xargs flatpak remove -y
  omarchy-show-done
fi
```

`file: /omarchy-flatpak-install`
```bash
#!/bin/bash

fzf_args=(
  --multi
  --preview 'flatpak remote-info flathub {2}'
  --preview-label='alt-p: toggle description, alt-j/k: scroll, tab: multi-select, F11: maximize'
  --preview-label-pos='bottom'
  --preview-window 'down:65%:wrap'
  --bind 'alt-p:toggle-preview'
  --bind 'alt-d:preview-half-page-down,alt-u:preview-half-page-up'
  --bind 'alt-k:preview-up,alt-j:preview-down'
  --color 'pointer:green,marker:green'
)

pkg_names=$(flatpak remote-ls | fzf "${fzf_args[@]}")

if [[ -n "$pkg_names" ]]; then
  echo "$pkg_names"
  echo "$pkg_names" | awk '{print $2}'
  # Convert newline-separated selections to space-separated for yay
  echo "$pkg_names" | awk '{print $2}' | xargs flatpak install -y
  omarchy-show-done
fi
```

Make sure to mark them as executable with the command `chmod +x ~/.local/bin/*`

### Tips
#### vscode (electron)
For something like vscode, you may need to run some of these commands:
[Visual Studio Code (Flatpak) not launching](https://github.com/YaLTeR/niri/issues/1731#issuecomment-3217469702)
```bash
flatpak override --user --nosocket=wayland com.visualstudio.code;
flatpak override --user com.visualstudio.code --filesystem=host --socket=x11 --socket=wayland;
```

And i suspect this is the case for other electron based flatpaks as well

#### omarchy-menu hotkey
omarchy-menu command should point to the new bin file we creted (can varify in terminal), but when using the hotkey, it loads up the one in the omarchy bin directory. So youll need to do something to override this. What i did was:

`file: ~/.config/hypr/bindings.conf`
```bash
... others
unbind = SUPER ALT, SPACE
bindd = SUPER ALT, SPACE, Omarchy menu, exec, ~/.local/bin/omarchy-menu
```
