Flatpak is a Linux application sandboxing and distribution framework.

Usage

Using this configuration, flatpak will be installed and ready to use globally for all users:

/etc/nixos/configuration.nix

services.flatpak.enable = true;

If you'd rather make flatpak available to a specific user, add flatpak to that user's packages. To be able to install flatpaks graphically, add the gnome.gnome-software package. The result will look something like this:

/etc/nixos/configuration.nix

  users.users.'&lt;user&gt;' = {
    packages = with pkgs; [
      flatpak
      gnome.gnome-software
    ];
  };

After adding the desired solution to your configuration file, flatpak will be installed, but it is not always added to your path directly, e.g. when you are using Sway.

To manually add it to the path while using the greetd login manager and Sway, create a .profile file with an override for your XDG_DATA_DIRS path, e.g.:

.profile

export XDG_DATA_DIRS=$XDG_DATA_DIRS:/usr/share:/var/lib/flatpak/exports/share:$HOME/.local/share/flatpak/exports/share

This is also required when installing flatpak on a per-user basis.

To start using flatpaks, particularly for flatpak development:

$ flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo
$ flatpak update
$ flatpak search bustle
$ flatpak install flathub org.freedesktop.Bustle
$ flatpak run org.freedesktop.Bustle

Development

Build a Flatpak project

The following example builds a demo project of the libhandy repository using flatpak-builder, installs it locally in the user space and runs it. First install flatpak and flatpak-builder on your system

/etc/nixos/configuration.nix

services.flatpak.enable = true;
environment.systemPackages = [ pkgs.flatpak-builder ];

Clone, build and run the example project. For now, a patch for libhandy might be required to fix a bug in the build process.

$ flatpak remote-add --if-not-exists gnome-nightly https://nightly.gnome.org/gnome-nightly.flatpakrepo
$ flatpak install org.gnome.Sdk/x86_64/master org.gnome.Platform/x86_64/master
$ git clone https://gitlab.gnome.org/GNOME/libhandy.git
$ cd libhandy
$ flatpak-builder --user --install _flatpak examples/sm.puri.Handy.Demo.json
$ flatpak run sm.puri.Handy.Demo

Note that the gnome-nightly repository and its dependencies are especially required for this specific project and might be different for other Flatpak projects.

Troubleshooting
