Authentication

Before using most CLI commands, you'll need to authenticate with Stac Cloud.

Login

# Authenticate with Google OAuth
stac login
# This opens your browser for OAuth authentication# Your credentials are securely stored locally

Check Status

# Check your authentication status
stac status

Logout

# Clear stored authentication tokens
stac logout

Initialize Stac

Use this to set up Stac in an existing Flutter/Dart project. It links your local app to a Stac Cloud project and scaffolds required files.

⚠️Note: You must be authenticated (stac login) before running stac init.

# Initialize Stac in the current project
stac init

What it does

• ✅ Creates stac/ folder for Stac DSL widgets
• ✅ Adds lib/default_stac_options.dart with your StacOptions (e.g., projectId)
• ✅ Updates pubspec.yaml with stac and related dependencies
• ✅ Optionally links to an existing Stac Cloud project

Building Widgets

Convert Dart to JSON

# Build all widgets in current project
stac build
# Build specific project directory
stac build --project /path/to/project
# Build with validation (enabled by default)
stac build --validate
# Build with verbose output
stac build --verbose

Build Options

Option	Description	Default
-p, --project	Project directory path	Current directory
--validate	Validate generated JSON	true
-v, --verbose	Show detailed build output	false

The build command converts Stac widget definitions from the stac/ folder into JSON format in the build/ folder.

Deployment

Deploy to Stac Cloud

# Build and deploy to Stac Cloud
stac deploy
# Deploy specific project directory
stac deploy --project /path/to/project
# Skip build and deploy existing files
stac deploy --skip-build
# Deploy with verbose output
stac deploy --verbose

Deployment Options

Option	Description	Default
-p, --project	Project directory path	Current directory
--skip-build	Skip building before deployment	false
-v, --verbose	Show detailed deployment output	false

Note: By default, stac deploy automatically runs stac build before deploying. Use --skip-build to deploy existing build files without rebuilding.

Cloud Project Management

List Projects

# List all your Stac Cloud projects
stac project list
# Output as JSON format
stac project list --json

The list command shows:

• 📋 Project name and ID
• 📝 Project description
• 📅 Created and updated timestamps

Create New Project

# Create a new project on Stac Cloud
stac project create --name "My App" --description "My SDUI app"# Short form
stac project create -n "My App" -d "My SDUI app"

After creating a project, run stac init to initialize it locally.

Development Workflow

🚀 Quick Start

Here's a typical workflow to get started with Stac CLI:

# 1. Authenticate with Stac Cloud (one-time setup)
stac login
# 2. List available projects (optional)
stac project list
# 3. Navigate to your Flutter/Dart projectcd your-flutter-project
# 4. Initialize Stac in your project
stac init
# 5. Create your widget definitions in the stac/ folder# Edit stac/your_screen.dart with your Stac widgets# 6. Build and deploy to Stac Cloud
stac deploy

🔄 Development Cycle

Once set up, your typical development cycle will be:

# Make changes to widgets in stac/ folder# ...# Build and deploy changes
stac deploy
# Or build locally first to test
stac build
stac deploy --skip-build
