🛠️ Asset Generator #

A simple and flexible Dart/Flutter CLI tool to auto-generate asset reference classes and barrel files — making asset management and file exports clean, consistent, and error-free.

✨ Features #

✅ Automatically scans asset folders and generates Dart class with constant paths
✅ Supports nested folders and various file types (.png, .svg, .json, etc.)
✅ Converts file names to camelCase constants for easy reference
✅ Works in Flutter and pure Dart projects
✅ Fully customizable class name and output structure
✅ Also supports barrel file generation: auto-exports multiple Dart files from any directory
✅ CLI-ready, no runtime dependency

📦 Use Cases #

• Generate an AppImages class to avoid hardcoding asset paths
• Organize all custom widgets via a single widget_exports.dart barrel file
• Reduce boilerplate and avoid human error in large projects
• Keep imports clean and scalable in modular architecture

🚀 Getting Started #

🔧 Installation #

Add this package to your dev_dependencies:

dev_dependencies:
  smart_asset_generator: ^0.0.6

Or use the path version locally during development:

dev_dependencies:
  smart_asset_generator:
    path: ../smart_asset_generator

Run pub get or flutter pub get.

🏃‍♂️ CLI Usage #

🖼️ Generate Asset Reference Class #

dart run smart_asset_generator <asset_path> [class_name]

✅ Example

dart run smart_asset_generator assets/images AppImages

Generates:

// lib/generated/app_images.dart
class AppImages {
  AppImages._();

  static const String icGoogle = 'ic_google.png';
  static const String icArrowRight = 'ic_arrow_right.svg';
}

Use it like:

Image.asset(AppImages.icGoogle);

📦 Generate Barrel File #

dart run asset_generator barrel <directory> [output_file_name]

✅ Example

dart run smart_asset_generator barrel lib

dart run smart_asset_generator barrel lib/widgets widget_exports

Generates:

// lib/widgets/widget_exports.dart
export 'button/custom_button.dart';
export 'form/input_field.dart';
export 'layout/grid_view.dart';

This allows clean imports in your app:

import 'package:your_app/widgets/widget_exports.dart';
