To run flatpak installed apps from dmenu.

flatpak-dmenu.md

To run a flatpak app from dmenu, you can create a symlink for the app in /usr/bin. You can find the flatpak apps binary link in /var/lib/flatpak/exports/bin/ on ubuntu. E.g. to run Rocket Chat (installed from flatpak via software center), you can do something like this:

sudo ln -s /var/lib/flatpak/exports/bin/chat.rocket.RocketChat /usr/bin/rocket-chat

This way you will be able to find it in the dmenu.

The best approach I found was using i3-dmenu-desktop.

1. Search for then change the `dmenu_run` in the i3config or if you have the default config you'll see alternatives slightly below the default line for `dmenu_run`.

2. Adjust accordingly using `rofi` or `i3-dmenu-desktop` by commenting/uncommenting.

Both rofi and i3-dmenu-deskotp ran on my system to display flatpaks without any other changes to the system.

This is the best answer so far.. nothing to do but to add a binding in the config

bindsym $mod+Shift+d exec --no-startup-id i3-dmenu-desktop

then reload config.. then execute the binding and i3-dmenu-desktop give you list of apps that can run in the desktop, INCLUDING the flatpaks..
