📦 Barrel Generator

The Barrel Generator is a CLI tool written in Go that automates the creation of export files (barrel files) for Dart/Flutter projects. It scans a directory and generates a <folder_name>_exports.dart file containing all necessary exports, organized automatically.

🚀 Installation

1️⃣ Download and Compile the Code

If you already have Go installed, you can compile the binary directly:

# Clone the repository
git clone <REPOSITORY_URL>
cd <PROJECT_FOLDER>

# Compile the binary
go build -o barrel_gen

# Move it to a globally accessible location
mv barrel_gen ~/go/bin/   # Or sudo mv barrel_gen /usr/local/bin/

Now, you can run the barrel_gen command from anywhere in the terminal.

🎯 How to Use

The Barrel Generator allows you to create export files for any folder in your Dart/Flutter project.

🔹 Automatically Generate an Export File

barrel_gen -dir=lib/features/user/models

If the models folder contains .dart files, it will generate:

lib/features/user/models/models_exports.dart

🔹 Specify a Custom Output Name

barrel_gen -dir=lib/features/user/models -o=lib/features/user/models.dart

This will create a file with a different name:

lib/features/user/models.dart

---

🛠 Example Usage

If we run:

barrel_gen -dir=lib/models

And the lib/models folder contains the following files:

lib/models/
│── user.dart
│── product.dart
│── order.dart
│── user.freezed.dart  (ignored)
│── user.g.dart        (ignored)

The generated models_exports.dart file will be:

// 📦 Automatically generated file. DO NOT EDIT MANUALLY.

export 'user.dart';
export 'product.dart';
export 'order.dart';

Organizing your files in Flutter has never been easier! 🚀
