# Project Constitution: Mobile Application ## Project Principles ### 1. Mobile-First Design - Design for touch interactions - Optimize for battery life and data usage - Support offline-first functionality - Follow platform guidelines (iOS/Android) ### 2. Performance - App launch time < 2s - 60 FPS animations - Bundle size < 50MB - Minimize API calls and data transfer ### 3. Cross-Platform Consistency - Shared business logic (React Native/Flutter) - Platform-specific UX where appropriate - Maintain single codebase for iOS and Android ### 4. User Experience - Native-feeling interactions - Intuitive navigation - Proper loading states - Graceful error handling ## Technical Constraints - **Framework**: React Native 0.72+ or Flutter 3.10+ - **Min iOS**: 14.0 - **Min Android**: API 26 (Android 8.0) - **Bundle Size**: < 50MB download - **Startup Time**: < 2s cold start ## Library Preferences ### React Native - **Navigation**: React Navigation 6+ - **State**: React Query + Zustand - **Forms**: React Hook Form + Zod - **Storage**: MMKV or AsyncStorage - **Network**: Axios with interceptors ### Flutter - **State**: Riverpod or Bloc - **Navigation**: GoRouter - **Storage**: Hive or sqflite - **Network**: Dio with interceptors ## Architecture - Feature-based modules - Clean Architecture or MVVM - Repository pattern for data - Service layer for business logic --- *Optimized for React Native and Flutter cross-platform development*
