Flatline was created to facilitate the installation process of Flatpak applications from the websites flathub.org, app.gnome.org and appcenter.elementary.io.

Donations

Known Limitations

Flatline basically uses AppStream to tell GNOME Software (or any software center with Flatpak support) which app to show, however there is no way to specify which repository to show. When opening it will be necessary to manually choose the repository. If you use distributions that focus heavily on using Flatpaks like Fedora Silverblue, you won't notice this.

Development

1. Clone the repository
2. Open Firefox browser and navigate to about:debugging
3. Click "Load Temporary Add-on" and from the file browser, choose manifest.json

Special thanks

I want to thank Lains for taking the trouble to create such a cool icon, thanks also to Nahuel for bringing the idea to the table.
