Premium GetX Flutter Boilerplate 🚀 #

A production-ready, highly organized Flutter starter template built with GetX, Clean Feature-First Architecture, Centralized Dependency Injection, Singleton Routing, high-performance Singleton Network Clients, and deeply customizable Premium Common UI Components.

This template is meticulously structured for maximum code readability, rapid developer onboarding, and scalability, making it the perfect foundation for any enterprise-grade mobile application.

⚡ Quick Start with CLI #

Instead of manual cloning and search-and-replace, you can use our official GetX Boilerplate CLI from pub.dev to instantly scaffold a new project with this template, automatically configured with your custom project name:

1. Install the CLI globally #

dart pub global activate getx_boilerplate_cli

2. Scaffold a new project #

getx_boilerplate_cli create my_awesome_app

This will automatically:

Clone the latest template from GitHub.
Clear git history to start a new project.
Rename all package imports and declarations from getx_template to my_awesome_app.
Run flutter pub get so you are ready to code immediately!

🚀 Architectural Overview #

We follow an organized, domain-driven Feature-First Architecture. All custom UI widgets are unified under a standard Common design system (replacing standard platform-specific prefixes).

📦 Key Core Architectures #

1. Centralized Global Dependency Injection #

All GetX controllers are managed in a single, robust centralized file: lib/core/bindings/dependency_injection.dart. Using Get.lazyPut(..., fenix: true) ensures that controllers are memory-efficiently instantiated only when needed and automatically recreated when accessed again, eliminating memory leaks. Global services (like ConnectivityService or SharedPreferencesService) are registered as permanent dependencies.

class DependencyInjection extends Bindings {
  @override
  void dependencies() {
    Get.putAsync(() => AppLifecycleObserver().init());
    
    // Services
    Get.lazyPut(() => SharedPreferencesService.instance, fenix: true);
    Get.put(ConnectivityService(), permanent: true);
    Get.put(DialogService(), permanent: true);
    
    // Controllers
    Get.lazyPut(() => SplashController(), fenix: true);
    Get.lazyPut(() => OnboardingController(), fenix: true);
    Get.lazyPut(() => AuthController(), fenix: true);
  }
}

2. Singleton Routing System #

All route constants and screen mappings are neatly encapsulated within a single Singleton class in lib/core/routing/app_routes.dart. This removes clutter and makes route declaration clean and human-readable.

GetMaterialApp(
  initialRoute: AppRoutes.splash,
  getPages: AppRoutes.instance.routes,
  unknownRoute: AppRoutes.instance.unknownRoute,
);

3. High-Performance Network & Connectivity Clients #

ApiClient (Dio Singleton):
- Exposes clean HTTP methods: .get(), .post(), .put(), .patch(), .delete().
- Multipart Uploads: Built-in support for uploading forms/files via multipartUpload with progress callbacks.
- Resiliency: Automatic global API interception, authorization token injection, network logs, and standard NetworkException conversion.
ConnectivityService (Connection Observer):
- Listens to dynamic internet status changes.
- Exposes reactive boolean status updates using GetX RxBool (isConnected.value).

🚀 How to Add a New Feature #

Adding a new module (e.g., chat) is extremely simple:

Create folders:

lib/features/chat/
├── data/
│   └── model/
└── screen/
    ├── controller/ (chat_controller.dart)
    ├── view/       (chat_screen.dart)
    └── widget/     (local_widget.dart)

Declare routing: Add your route to lib/core/routing/app_routes.dart:

static const String chat = '/chat';
    
// Add inside List<GetPage> routes list:
GetPage(name: chat, page: () => const ChatScreen()),

Register the Controller: Add your controller inside the centralized file lib/core/bindings/dependency_injection.dart:
```
Get.lazyPut(() => ChatController(), fenix: true);
```

Inject the Controller inside your View:

class ChatScreen extends StatelessWidget {
  const ChatScreen({super.key});

  @override
  Widget build(BuildContext context) {
    final controller = Get.find<ChatController>();
    return CommonScaffold(
      appBar: const CommonTopBar(title: 'Chat'),
      body: ...
    );
  }
}

📱 Premium High-Readability Extensions #

Unified extension methods reduce widget layout tree nesting:

1. Spacing Extensions (`lib/core/utils/extenstion/screen_extensions.dart`) #

Append .height or .width to integers or doubles for responsive layout spacing:

16.height — Responsive SizedBox(height: 16.h)
24.width — Responsive SizedBox(width: 24.w)

2. Context Extensions (`lib/core/utils/extenstion/context_extensions.dart`) #

Directly access themes, color schemes, and screen dimension constraints from the current context:

context.theme — Quick access to Theme.of(context)
context.colorScheme — Quick access to the color scheme tokens
context.screenWidth — Current display width

3. Widget Layout Extensions (`lib/core/utils/extenstion/widget_extensions.dart`) #

Add responsiveness, paddings, and alignment inline without wrapping widgets manually:

widget.paddingAll(16.h)
widget.paddingSymmetric(horizontal: 20.w)
widget.visible(condition)

Example usage:

import 'package:getx_template/core/utils/extenstion/screen_extensions.dart';
import 'package:getx_template/core/utils/extenstion/context_extensions.dart';
import 'package:getx_template/core/utils/extenstion/widget_extensions.dart';

@override
Widget build(BuildContext context) {
  return Column(
    children: [
      CommonText(
        'Workspace Settings',
        style: context.textTheme.headlineMedium,
        color: context.colorScheme.primary,
      ),
      12.height,
      CommonText(
        'Subheading',
        style: context.textTheme.bodyMedium,
      ).paddingSymmetric(horizontal: 16.w),
    ],
  );
}

🔐 System Services & Helpers #

1. System Permissions Utility (`PermissionHelper`) #

Managed under lib/services/permissions/permission_helper.dart, this helper allows silent checking of permission states before request triggers:

// Check if access is already granted
final bool isAlreadyGranted = await PermissionHelper.check(Permission.camera);

if (!isAlreadyGranted) {
  // Triggers native system prompt dialog
  final bool status = await PermissionHelper.camera();
  if (!status) {
    // If permanently denied, prompt user to redirect to App System Settings
    await openAppSettings();
  }
}

2. URL & Intent Launcher Helper (`UrlLauncherHelper`) #

Easily trigger email intents, website URLs, and external applications securely:

UrlLauncherHelper.email("support@example.com");
UrlLauncherHelper.open("https://pub.dev");

🔧 Useful Commands #

# Fetch package dependencies
flutter pub get

# Format your codebase
dart format lib/

# Run static analysis check
flutter analyze

# Launch application on emulator / device
flutter run

Happy coding! This template is designed to give you standard-setting performance and premium user experience from day one.
