flutter_smartgen 0.5.0

CLI that scaffolds Flutter feature-module pages with GetX, registers routes, syncs AppImages, creates environment files, and scaffolds lib/app. Configure via smartgen.yaml.

flutter_smartgen

CLI for Flutter apps using GetX. Scaffolds feature-module pages, registers routes, and syncs AppImages from asset folders.

Run from your Flutter project root (pubspec.yaml + lib/).

---

Quick start

smartgen init
smartgen page profile --route
smartgen assets images

What you get

• smartgen.yaml — project config
• lib/screens/profile_screen/ — 6 files (view, controller, binding, repository, model, barrel)
• lib/router/app_routes.dart + app_pages.dart — route constant + GetPage (created if missing)
• lib/app/app_images.dart — asset constants from your folders

Build your UI inside _mainBody() in the generated view.

---

Examples

Run smartgen page profile --route in a project named my_app.

Page module (lib/screens/profile_screen/)

profile_screen/
├── profile.dart                              # barrel exports
├── binding/profile_screen_binding.dart
├── controller/profile_screen_controller.dart
├── resource/
│   ├── model/profile_model.dart
│   └── repository/profile_screen_repository.dart
└── view/profile_screen.dart

view/profile_screen.dart

class ProfileScreen extends GetView<ProfileController> {
  const ProfileScreen({super.key});

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: _mainBody(context),
    );
  }

  Widget _mainBody(BuildContext context) {
    return const SizedBox();   // add your UI here
  }
}

binding/profile_screen_binding.dart

class ProfileScreenBinding extends Bindings {
  @override
  void dependencies() {
    Get
      ..lazyPut<ProfileScreenRepository>(ProfileScreenRepository.new)
      ..lazyPut<ProfileController>(
        () => ProfileController(Get.find<ProfileScreenRepository>()),
      );
  }
}

Routes (--route or smartgen route profile)

lib/router/app_routes.dart — constant appended:

class AppRoutes {
  AppRoutes._();

  static const String profilePage = '/profile';
}

lib/router/app_pages.dart — imports + GetPage appended:

import 'package:my_app/screens/profile_screen/binding/profile_screen_binding.dart';
import 'package:my_app/screens/profile_screen/view/profile_screen.dart';

class AppPages {
  AppPages._();

  static final List<GetPage<dynamic>> getPages = <GetPage<dynamic>>[
    GetPage<dynamic>(
      name: AppRoutes.profilePage,
      binding: ProfileScreenBinding(),
      page: () => const ProfileScreen(),
    ),
  ];
}

If lib/router/ does not exist, the first route command creates these files automatically.

AppImages (smartgen assets images)

Given assets/images/ic_back.svg and assets/icons/search_icon.svg in your yaml directories:

lib/app/app_images.dart

class AppImages {
  AppImages._();

  /// Images
  static const String icBack = 'assets/images/ic_back.svg';

  /// Icons
  static const String searchIcon = 'assets/icons/search_icon.svg';
}

Re-runs add new files, skip existing constants, and remove entries when the asset file was deleted.

Environment files (smartgen env)

.env.development and .env.production (project root):

# Generated by smartgen env — add real values locally; do not commit secrets.
BASE_URL=
API_KEY=

Add both files to .gitignore. Load with flutter_dotenv if needed.

App folder (smartgen app)

Creates lib/app/ scaffold files (skip if exist). All files or one by name:

smartgen app
smartgen app fonts
smartgen app class

app_class.dart — singleton with default loading state:

class AppClass {
  factory AppClass() => _singleton;
  AppClass._internal();
  static final AppClass _singleton = AppClass._internal();

  RxBool isLoading = false.obs;
}

Other files (AppColors, AppConstants, AppStrings, …) are empty class shells. Run smartgen assets images to fill AppImages.

Valid names: barrel, colors, constants, strings, images, fonts, lists, enum, dialogue, class, translation.

---

Install

Global (any project)

dart pub global activate flutter_smartgen
export PATH="$PATH:$HOME/.pub-cache/bin"   # add to ~/.zshrc or ~/.bash_profile

Windows or issues? Set up your path.

Dev dependency (recommended for teams)

dev_dependencies:
  flutter_smartgen: ^0.5.0

dart pub get
dart run flutter_smartgen:smartgen init

Important: With a dev dependency, always use dart run flutter_smartgen:smartgen … — not smartgen ….

Example:

dart run flutter_smartgen:smartgen page profile --route

---

Commands

Command	Description
smartgen init	Create smartgen.yaml
smartgen env	Create .env.development and .env.production (skip if exist)
smartgen app [name]	Create lib/app/ scaffold files (all or one: fonts, colors, …)
smartgen page <name>	Generate a screen module (6 files)
smartgen page <name> --route	Generate module + register route
smartgen route <name>	Register route only (module must exist)
smartgen assets images	Sync AppImages from asset folders

Existing page, env, and app files are never overwritten. Re-runs skip what already exists.

---

Configuration

smartgen init writes smartgen.yaml:

package_name: my_app
screens_base: lib/screens

naming:
  screen_suffix: Screen
  controller_suffix: Controller

routes:
  routes_file: lib/router/app_routes.dart
  pages_file: lib/router/app_pages.dart
  routes_class: AppRoutes
  pages_class: AppPages
  route_name_suffix: Page

assets:
  images:
    output: lib/app/app_images.dart
    class_name: AppImages
    directories:
      - assets/images

Optional: uncomment common_scaffold in yaml to use your shared scaffold instead of Scaffold.

For assets images: add files under assets/images, list folders in pubspec.yaml → flutter: assets:, then run the command. New files are added, deleted files are removed from AppImages.

---

Naming

Input	Module folder	Route constant	Path
profile	profile_screen/	profilePage	/profile
sign_up	sign_up_screen/	signUpPage	/sign_up

Classes use your naming suffixes (default: ProfileScreen, ProfileController).
