Can not find executable path of flatpak apps

Question

App installed using apt package manager starts running when I type the app name in terminal like firefox. [Using Kubuntu 22.04]

which firefox

This command will show the path of firefox in my system.

In case of Flatpak apps, how to run the the flatpak app without

flatpak run org.mozilla.firefox

So, how can I find flatpak app's path like which firefox.

I need it so that I can set brave browser app in $CHROME_EXECUTABLE path for flutter development.

Answer 1

which returns the full pathname of an executable, provided it exists in one of the directories listed in the search PATH. flatpak exposes executables for installed applications in /var/lib/flatpak/exports/bin. However, that directory is not automatically included in the PATH when you install flatpak. You could include it in the PATH yourself. Then, you could launch the Firefox version installed by flatpak with the command org.mozilla.firefox.

You can always launch an executable by providing the full path name:

/var/lib/flatpak/exports/bin/org.mozilla.firefox

So you can just set the variable as:

CHROME_EXECUTABLE=/var/lib/flatpak/exports/bin/org.mozilla.firefox

So, how can I find flatpak app's path like which firefox.

Just by being informed about how flatpak does it, or from the documentation. No tool can provide that information if the executable is not in the path or if you do not know the name of the executable.
