{ pkgs, … }: {

Which nixpkgs channel to use.

channel = “stable-24.05”; # or “unstable”

Use NixOS Search to find packages

packages = [
pkgs.jdk17
pkgs.unzip
pkgs.sudo
pkgs.screenfetch
# pkgs.cocoapods
pkgs.systemd
];

Sets environment variables in the workspace

env = { };
idx = {
# Search for the extensions you want on https://open-vsx.org/ and use “publisher.id”
extensions = [
“Dart-Code.flutter”
“Dart-Code.dart-code”
“Github.vscode-github-actions”
“Github.github-vscode-theme”
“Gruntfuggly.todo-tree”
“aaron-bond.better-comments”
“usernamehw.errorlens”
“vscode.image-preview”
“Nash.awesome-flutter-snippets”

  # Runs when a workspace is first created with this `dev.nix` file

Create a new project, copy the dev.nix from that project, paste the contents into your 115GB VM, and restart.
