NixOs issues with flutter run


I'm on nixOS and trying to start a flutter project. When I hit flutter run the following error occures.

* What went wrong:
Error resolving plugin [id: 'dev.flutter.flutter-gradle-plugin', version: '1.0.0']
> A problem occurred configuring project ':gradle'.
   > Could not create service of type OutputFilesRepository using ExecutionGradleServices.createOutputFilesRepository().
      > Failed to create parent directory '/nix/store/lbi43bsi63zvp7wjgswsp1vjrg4pv9b2-flutter-3.13.4-unwrapped/packages/flutter_tools/gradle/.gradle' when creating directory '/nix/store/lbi43bsi63zvp7wjgswsp1vjrg4pv9b2-flutter-3.13.4-unwrapped/packages/flutter_tools/gradle/.gradle/buildOutputCleanup'

Had anyone this issue and know how to resolve it? I understand that everything in /nix/store is read-only, but this should somehow work.


Solution

  • I was encountering similar Gradle errors. In the end, I managed to successfully build the .apk with Flutter on NixOS using this nix develop and this flake

    {
      description = "moxplatform";
      inputs = {
        # nixpkgs.url = "github:NixOS/nixpkgs/nixpkgs-unstable";
        nixpkgs.url = "github:NixOS/nixpkgs/23.05";
        flake-utils.url = "github:numtide/flake-utils";
        android-nixpkgs.url = "github:tadfisher/android-nixpkgs";
      };
    
      outputs = { self, nixpkgs, flake-utils, android-nixpkgs }: flake-utils.lib.eachDefaultSystem (system: let
        pkgs = import nixpkgs {
          inherit system;
          config = {
            android_sdk.accept_license = true;
            allowUnfree = true;
          };
        };
        # Everything to make Flutter happy
