blue_bird_cli 1.0.0

A powerful CLI tool to kickstart your Flutter projects with clean, scalable architectures that grow with your app.

Blue Bird CLI 🐦

Build scalable Flutter apps with confidence.

Blue Bird CLI generates production-ready Flutter projects with clean architecture, workspace management, and automated dependency injection. Choose from lite templates for small apps or complex multi-package architectures for enterprise-scale applications.

Inspired by Very Good CLI 🤖

Installation 🚀

dart pub global activate blue_bird_cli

Quick Start

# Create a lite app (small to medium projects)
blue_bird create lite_app -t flutter_lite

# Create a full-scale app (complex, enterprise projects)
blue_bird create full_app

# Add a feature package to an existing project
blue_bird create my_feature -t flutter_package -o "full_app/packages"

---

Templates

🪶 Flutter Lite

Perfect for small to medium-sized projects

A streamlined single-app structure with clean architecture, ideal for apps that need organization without the complexity of multi-package workspaces.

blue_bird create lite_app -t flutter_lite --org com.mycompany

Structure:

lite_app/
├── lib/
│   ├── main.dart
│   └── src/
│       ├── config/         # DI, routes, l10n, theming
│       ├── data/           # Repositories, data sources, models
│       ├── domain/         # Entities, use cases, repository interfaces
│       └── presentation/   # Pages, widgets, view models
├── assets/
└── test/

🏗️ Flutter Project

Built for complex, scalable applications

A comprehensive multi-package architecture with clean architecture patterns, perfect for large teams and enterprise apps.

blue_bird create full_app

Structure:

full_app/
├── core/              # Foundation layer
├── design_system/     # UI system
├── packages/          # Feature packages
│   └── bb_example_package/
│   └── ...
└── lib/               # Main app

📦 Flutter Package

Modular feature development

Generate feature packages with clean architecture (data, domain, presentation layers) that automatically integrate with your workspace.

cd full_app/packages
blue_bird create my_feature -t flutter_package

Auto-configured:

• ✅ Added to workspace
• ✅ Added to dependencies
• ✅ DI configuration injected

Architecture & Dependencies

Blue Bird enforces a clear dependency hierarchy to maintain scalability:

graph TD
    A[Main App] --> B[design_system]
    A --> C[core]
    A --> D[packages/*]
    B --> C
    D --> B
    D --> C
    
    style A fill:#4CAF50
    style B fill:#2196F3
    style C fill:#FF9800
    style D fill:#9C27B0

Dependency Rules:

• Main App → Can use all packages
• design_system → Can use core only
• core → No internal dependencies (foundation layer)
• packages/ → Can use core and design_system
• packages/ → ❌ Cannot depend on each other (no cyclic dependencies)

This ensures maintainability and prevents circular dependencies as your app grows.

---

Package Structure

Feature packages follow clean architecture with three distinct layers:

Domain Layer (Business Logic)

• Entities, repositories interfaces, use cases

Data Layer (Implementation)

• Repository implementations, data sources, models

Presentation Layer (UI)

• Pages, widgets, state management (Cubit/BLoC)

Example: bb_example_package

bb_example_package/
├── lib/src/
│   ├── domain/
│   ├── data/
│   ├── presentation/
│   └── config/di/

Commands

Create Projects & Packages

# Lite template
blue_bird create lite_app -t flutter_lite
