Flutter

Development

Create following flake.nix in a new project directory

/etc/nixos/flake.nix

{
description = "Flutter 3.0.4";
inputs = {
  nixpkgs.url = "github:NixOS/nixpkgs/23.05";
  flake-utils.url = "github:numtide/flake-utils";
};
outputs = { self, nixpkgs, flake-utils }:
  flake-utils.lib.eachDefaultSystem (system:
    let
      pkgs = import nixpkgs {
        inherit system;
        config = {
          android_sdk.accept_license = true;
          allowUnfree = true;
        };
      };
      buildToolsVersion = "30.0.3";
      androidComposition = pkgs.androidenv.composeAndroidPackages {
        buildToolsVersions = [ buildToolsVersion "28.0.3" ];
        platformVersions = [ "31" "28" ];
        abiVersions = [ "armeabi-v7a" "arm64-v8a" ];
      };
      androidSdk = androidComposition.androidsdk;
    in
    {
      devShell =
        with pkgs; mkShell rec {
          ANDROID_SDK_ROOT = "${androidSdk}/libexec/android-sdk";
          buildInputs = [
            flutter
            androidSdk
            jdk11
          ];
        };
    });
}

Run following commands to start a new demo project and run the "hello world" application

# flutter create my_app
# cd my_app
