arcle 2.1.1

Agentic Flutter Development Platform — scaffold Clean Architecture projects with BLoC, GetX, or Riverpod, and configure AI agent support.

ARCLE CLI

Agentic Flutter Development Platform — scaffold Clean Architecture projects with BLoC, GetX, or Riverpod, and configure AI agent support for Claude Code, Codex, and Gemini.

Why ARCLE

ARCLE removes repetitive setup work for scalable Flutter apps.

• Create a project with Clean Architecture structure
• Choose BLoC, GetX, or Riverpod
• Generate full feature modules
• Keep DI and route wiring consistent
• API client ready with Dio
• Session management & token handling
• Multi-language support
• Environment configuration (local, staging, production)
• Working demo feature with login & API integration
• Auto-generated documentation
• Production-ready code structure
• Build APKs from the CLI
• AI agent context generation — Claude Code, Codex, Gemini out of the box

What's New In 2.0.0

• Agentic Flutter Development Platform — every new project ships with .ai/ project context, coding rules, architecture rules, and security rules for any AI coding agent
• Claude Code integration — .claude/CLAUDE.md and .claude/settings.json generated automatically
• Codex integration — .codex/instructions.md and .codex/settings.json generated automatically
• Gemini integration — .gemini/GEMINI.md and .gemini/settings.json generated automatically
• New arcle agent command — add/remove/switch/list/validate AI agents
• New arcle ai command — init/sync/validate/doctor AI configuration
• New arcle upgrade command — upgrade existing projects to v2.0.0 (SDK constraint, dimensions, analysis options, .ai/ config, scripts)
• Universal Dimensions class — no longer depends on GetX; works across all state management options via dart:ui PlatformDispatcher
• Stricter linting — always_use_package_imports, avoid_unnecessary_containers, prefer_single_quotes, unnecessary_const, unnecessary_new added to generated analysis_options.yaml
• Setup & doctor scripts — scripts/setup.sh, scripts/setup.ps1, scripts/doctor.sh, scripts/doctor.ps1 generated in every project
• Minimum Dart SDK raised to >=3.7.0 <4.0.0

📦 Installation

Option 1: Activate globally (Recommended)

dart pub global activate arcle

Then use the arcle command directly from anywhere in your terminal.

Make sure your pub cache bin folder is in your PATH:

• Linux/macOS: $HOME/.pub-cache/bin
• Windows: %APPDATA%\Pub\Cache\bin

Add to your PATH if not already present:

• Linux/macOS: Add to ~/.bashrc or ~/.zshrc: export PATH="$PATH:$HOME/.pub-cache/bin"
• Windows: Use System Properties → Environment Variables → Add %APPDATA%\Pub\Cache\bin

Option 2: Run from pub

dart pub global activate arcle
arcle --help

Or use without activating:

dart pub global run arcle:arcle --help

State Management

ARCLE includes templates and generators for three state management solutions:

BLoC (Business Logic Component)

• Event-driven architecture
• Predictable state management with clear separation of concerns
• Automatic DI generation using GetIt and Injectable
• Best for: Complex apps with multiple features and events

GetX

• Lightweight and simple to use
• Reactive state management with bindings
• No build_runner needed
• Best for: Quick prototyping and small to medium apps

Riverpod

• Type-safe provider-based state management
• No context needed, functional approach
• Excellent for state composition
• Best for: Apps requiring strong typing and immutability

✅ Requirements

• Dart SDK: >=3.7.0 <4.0.0
• Flutter: 3.29.3 or higher
• Operating System: macOS, Linux, or Windows
• Terminal: bash, sh, zsh, or PowerShell

Platform Notes

• Android: ARCLE automatically configures Gradle build files with SDK versions (minSdk 21, compileSdk 35) and desugaring support for modern Java features. APK building is fully supported via arcle build apk.
• iOS: ARCLE automatically configures the iOS deployment target (13.0+) in Podfile and generates essential permission descriptions in Info.plist for camera, photos, microphone, location, calendar, and contacts access. Projects are ready for iOS development after creation.
• Generated notification and permission services include platform guards so unsupported platforms fail safely instead of crashing.
• Android and iOS are the primary supported mobile targets for the generated permission and local notification setup.
• iOS Release Builds: Remember to configure Apple signing in Xcode, set your Team ID, and manage provisioning profiles before building for distribution.
• Web is safe for shared app code, but local notifications and runtime permissions are intentionally treated as unsupported by default.
• macOS support is available in the generated code structure and is platform-safe, though features like permissions default to graceful failure.

Build Behavior

• arcle build apk --version-name ... --version-code ... rewrites the target project's pubspec.yaml version field before building
• arcle build apk --env prod|stag|local rewrites the target project's lib/core/env/env_factory.dart default environment before building
• These build changes are persistent in the target Flutter project
• Existing command forms remain fully supported; aliases are optional shortcuts only

🧪 Troubleshooting

Command Not Found: arcle

If you get "command not found: arcle" after global activation, ensure the pub cache bin is in your PATH:

# Check if dart is properly installed
dart --version

# Re-activate arcle
dart pub global activate arcle

# On Linux/macOS, add to your shell profile (~/.bashrc, ~/.zshrc, etc.)
export PATH="$PATH:$HOME/.pub-cache/bin"

# On Windows, use System Environment Variables
%APPDATA%\Pub\Cache\bin

Flutter SDK Not Found

ARCLE requires Flutter to be installed and available in PATH:

flutter --version
which flutter  # or 'where flutter' on Windows

Build Failures

Ensure you're using a compatible Flutter version:

flutter channel stable
flutter upgrade

🏛️ State Management Details

ARCLE generates different structures and setup requirements based on your chosen state management:

BLoC/Cubit Architecture

• Event-based state management with predictable patterns
• DI Setup: Uses GetIt + Injectable library
• Files Created:
  • lib/core/di/injection.dart - Service locator initialization
  • lib/core/di/injectable_module.dart - Dependency registration module
  • lib/core/di/injection.config.dart - Auto-generated dependencies (generated by build_runner)
  • lib/core/di/bloc_providers.dart - BLoC provider instances
• Localization: Creates assets/langs/en.json and assets/langs/bn.json
• Best For: Complex apps with multiple features and events
• Code Generation: Requires build_runner - run arcle auto-gen-di after adding features

GetX

• Lightweight and simple reactive state management
• Controller-based: Uses controller + binding pattern
• DI Setup: Service locator is built into GetX
• Files Created:
  • lib/core/localization/getx_localization.dart - GetX localization wrapper
  • Feature controller: lib/features/*/presentation/controller/*_controller.dart
  • Feature binding: lib/features/*/presentation/bindings/*_binding.dart
• Localization: Creates .gitkeep placeholder (you manage translations)
• Best For: Quick prototyping and small to medium apps
• Build Step: No additional build step required

Riverpod

• Type-safe provider-based state management
• Functional approach: Providers instead of classes
• DI Setup: Built into Riverpod providers
• Files Created:
  • lib/core/di/providers.dart - Core provider definitions
  • Feature providers: lib/features/*/presentation/providers/*_providers.dart
  • Feature state: lib/features/*/presentation/state/*_state.dart
• Localization: Creates assets/langs/en.json and assets/langs/bn.json
• Best For: Apps requiring strong typing and immutability
• Code Generation: Uses code generation for some features

📋 Feature Structure by State Management

Generated features have different presentation structure depending on state management:

BLoC:
lib/features/feature_name/presentation/
├── pages/
│   └── feature_name_screen.dart
├── widgets/
│   └── feature_name_card.dart
└── bloc/
    ├── feature_name_bloc.dart
    ├── feature_name_event.dart
    └── feature_name_state.dart

GetX:
lib/features/feature_name/presentation/
├── pages/
│   └── feature_name_screen.dart
├── widgets/
│   └── feature_name_card.dart
├── controller/
│   └── feature_name_controller.dart
└── bindings/
    └── feature_name_binding.dart

Riverpod:
lib/features/feature_name/presentation/
├── pages/
│   └── feature_name_screen.dart
├── widgets/
│   └── feature_name_card.dart
├── providers/
│   └── feature_name_providers.dart
└── state/
    └── feature_name_state.dart

• ❌ Add more demo features
• ❌ Support for custom templates

🤖 AI Agent Configuration

arcle create generates only the Flutter Clean Architecture structure. To add AI agent context files run this from your project root after creation:

arcle configure-ai   # interactive wizard — pick Claude / Codex / Gemini / All
arcle agent-init     # alias

This writes .ai/ context files plus the agent-specific directory (.claude/, .codex/, .gemini/) based on your selection. State management is read from arcle.yaml automatically.

🔍 Pre-Commit Code Review

arcle review              # analyze + format + missing-tests scan (fast, always-on)
arcle review --test       # also run flutter test
arcle review --coverage   # flutter test --coverage + report coverage %
arcle review --ai         # AI-assisted diff review (requires arcle configure-ai)
arcle review --staged     # diff only staged changes
arcle -r                  # shortcut alias

The missing-tests scan only checks files that appear in the current git diff — not the entire project — so it stays quiet until you actually change a file without a test.
