Applies generated libadwaita theme from wallpaper using Material You
Copy the extension to your extensions folder (create the folder if it does not exist).
git clone https://github.com/avanishsubbiah/material-you-theme
cd material-you-theme
make && make install
Log out and log back in and you should be able to enable it in your extension manager.
NOTE: Using the extension now will theme your native installed libadwaita apps, follow the steps below to have the theme apply to GTK3 and flatpak apps.
Theming for native libadwaita will work by default.
Install Flatseal, and add xdg-config/gtk-4.0:ro to Other Files under the category Filesystem in the All Applications section.
Install the adw-gtk3 theme and apply it.
After installing the adw-gtk3 add xdg-config/gtk-3.0:ro to Other Files under the category Filesystem in the All Applications section using Flatseal.
Once the extension is enabled the extension will update your theme based on your current wallpaper and system dark mode preference. When you change your system dark mode preference or wallpaper the extension will automatically refresh your theme.
Disabling the extension in your extension manager will undo theme changes back to default.
