Change theme of flatpak apps

[laguill]

Hello,

I am on xubuntu 23.10. The script is working very well to change Yaru from light to dark on native applications.

I would like to know how to change also the theme of flatpak applications.

At the moment I have this script but not really convenient...

[Desktop Entry]
Type=Application
Terminal=false
Name=Flatpak Dark Theme Switcher
Icon=org.gnome.Settings
Exec=gnome-terminal --title "Flatpak Dark Mode Switcher" -- sh -c 'while [ 1 -eq 1 ]; do echo "Press 1 for light theme, 2 for dark theme and hit enter"; read userInput; userInput=$(echo "$userInput" | xargs); if [ "$userInput" -eq "1" ]; then theme="Adwaita"; elif [ "$userInput" -eq "2" ]; then theme="Adwaita-dark"; else clear; echo "Invalid input, try again"; continue; fi; sudo flatpak override --env=GTK_THEME=$theme; sudo flatpak override --env=QT_STYLE_OVERRIDE=$theme; clear; echo "Operation Complete"; done;'

Can the script also handle this ?

Thanks for your help
