This project is built using the Flutter framework and the Dart programming language.
For the backend, it uses Supabase, a serverless platform. It includes:
- Deno functions written in TypeScript
- PostgreSQL scripts for database operations
Key Architectural Highlights:
- Offline-First: The app is designed to work fully offline (critical for
festivals). It uses a robust caching strategy (
OfflineDataService) and local databases. - SQL-Centric Logic: A significant portion of business logic (orders, games, permissions) resides in PostgreSQL Functions (RPC) rather than Dart code.
[!TIP] For Developers & AI Agents:
Please consult AI_README.md for a deep architectural deep-dive, component analysis, and "Split Brain" logic documentation.
The project uses a centralized configuration system driven by
automation/project.conf. This file is the single source of truth for:
- Deployment: Domain settings (
DOMAIN,CNAME). - Application: Supabase credentials (
SUPABASE_URL,ANON_KEY), Organization ID, and integration links. - Theme: Brand colors (
THEME_SEED_1...4) which are automatically applied to both Flutter (app_config.dart) and Web Client (theme_config.css). - Fonts: Font family configuration (
FONT_FAMILY_BASE) and form scaling. - Version: Application version (
VERSION), propagating topubspec.yaml,package.json, and the app.
After editing automation/project.conf, apply changes by running:
./automation/apply_config.shThis script automatically:
- Updates all relevant configuration files.
- Auto-detects and installs fonts from
automation/fonts/. - Synchronizes version numbers.

This project supports the Model Context Protocol (MCP) to allow AI assistants to interact with the project environment.
To enable AI agents to control a headless Chrome instance (e.g., for end-to-end testing or automation), use the Puppeteer MCP server:
./automation/start-mcp-puppeteer.shThis script exposes Chrome Developer Tools capabilities via the MCP protocol.
To enable AI agents to interact with the Supabase database and management API:
1. Postgres Database Access Allows direct SQL queries and schema inspection.
Requires DATABASE_URL in .env.local.
./automation/start-mcp-db.sh2. Supabase Management Allows project management and log inspection.
Requires SUPABASE_ACCESS_TOKEN in .env.local.
./automation/start-mcp-supabase.shThe app was originally developed by a team of volunteers for Absolventský Velehrad event in 2023.
