dart-flutter-nix's Issues

Web dev target?

This tool is very useful and I've successfuly built flutter projects with it.
But usually for developping apps I use the chrome target because it allows me to experiment with different viewport sizes.
Is support for the web option planned?

derivation has '__noChroot' set, but that's not allowed when 'sandbox' is 'true'

To reproduce:

  • git clone https://github.com/fzyzcjy/flutter_convenient_test
  • cd flutter_convenient_test/packages/convenient_test_manager
  • write the flake.nix:
{
  description = "test runner";

  inputs = {
    nixpkgs.url = "github:NixOS/nixpkgs";
    flake-utils.url = "github:numtide/flake-utils";
    dart-flutter.url = "github:flafydev/dart-flutter-nix";
  };

  outputs = { self, flake-utils, nixpkgs, dart-flutter }:
    flake-utils.lib.eachDefaultSystem
      (system:
        let
          pkgs = import nixpkgs {
            inherit system;
            overlays = [ dart-flutter.overlays.default ];
          };

        in
        {
          devShells.default = pkgs.mkFlutterShell {
            linux = {
              enable = true;
            };

            nativeBuildInputs = with pkgs; [ pkg-config openssl openssl.dev libdeflate ];
            buildInputs = with pkgs; [ openssl openssl.dev ];
            NIX_LD = pkgs.stdenv.cc.bintools.dynamicLinker;
            OPENSSL_ROOT_DIR = "${pkgs.openssl.dev}/include/openssl";
          };

          packages.default = pkgs.buildFlutterApp
            {
              pname = "convenient_test_manager";
              version = "0.0.1";
              src = ./.;
            };

        });
}
  • run pubspec-nix
  • run nix build
    • fails with error: derivation '/nix/store/rshlbapih5mgmd8s6hppfb54qsygq91k-flutter-desktop-embedding-6c66ad2.drv' has '__noChroot' set, but that's not allowed when 'sandbox' is 'true

temporary solution:

  • be a trusted user
  • nix build --impure --option sandbox false

questions:

  • why does this need noChroot?

Expose flutter for desktop dependencies?

Sometimes it would be useful to have just the dependencies needed for running flutter apps. Because this may change, this repo could serve as a single source o truth.

Context
  • flutter 3.7.3 is out for a while
  • there is a PR for it: NixOS/nixpkgs#215754
    • it is stuck because upstream broke aarch64
  • I rebased it to nixpkgs:master on http://github.com/gilice/nixpkgs
  • dart-flutter-nix wants to build its flutter with the patches for 3.3.8 and it breaks
error: builder for '/nix/store/varcv3marlwkzv49yqbzx2vhi6kf6mqb-flutter-unwrapped-3.7.3.drv' failed with exit code 1;

  • I temporarily skip using dart-flutter-nix and use simple nix instead
  • what I am looking for is exposing this libs variable externally for situations like this

Parallel dependency fetching?

pubspec-nix is pretty slow for even medium-sized projects, taking about 3 minutes to run here.

I wonder if we could improve on this by fetching dependencies in parallel, instead of sequentially.
I am not sure how one would do this in Python, as I haven't used that language much.

If no one else wants this, I might do a rewrite in Rust (oh god) using tokio just for fun.
We could even (oh god x2) do downloading one file in parallel with aria2.

Can't run "flutter run"

Hi, I can't build my existing app on nixos in the CLI. Not sure why though, maybe someone can shed light on this:

> flutter run

then
