What is the issue?

Description

I encountered an issue when using the flake configuration provided in the README of this repository. The configuration resulted in an error when trying to include Dagger as a package in a Nix development environment. Specifically, the error was: "attribute 'dagger' missing".

Steps to Reproduce

I used the flake configuration as given in the README, which is as follows:

{
  inputs = {
    nixpkgs.url = "nixpkgs/nixos-unstable";
    flake-utils.url = "github:numtide/flake-utils";
    dagger.url = "github:dagger/nix";
    dagger.inputs.nixpkgs.follows = "nixpkgs";
  };

  outputs = { self, nixpkgs, flake-utils, dagger, ... }:
    flake-utils.lib.eachDefaultSystem (system:
      let
        pkgs = nixpkgs.legacyPackages.${system};
      in {
        devShell = pkgs.mkShell {
          buildInputs = [ dagger.packages.dagger ];
        };
      });
}

Running nix develop with this configuration led to an error.

Suggested Fix

The issue was resolved by modifying the line in the devShell to reference the Dagger package for each system architecture specifically:

buildInputs = [ dagger.packages.${system}.dagger ];

Dagger version

dagger v0.9.4 (registry.dagger.io/engine) darwin/arm64
