Create world-class mobile app with advanced multi-language support
Built complete React Native mobile app from scratch with ZERO hard-coded language: 🌍 LANGUAGE SYSTEM (6 Languages): - EN (English), TR (Türkçe), KMR (Kurmancî), CKB (سۆرانی), AR (العربية), FA (فارسی) - User selects language on welcome screen - Language choice persists throughout entire app lifecycle - Settings screen allows language change anytime - NO hard-coded strings - all text uses i18next t() function - RTL support for Arabic, Sorani, and Persian - AsyncStorage saves user preference permanently ✅ IMPLEMENTED FEATURES: - Welcome screen with beautiful language picker (Kurdistan gradient) - Sign In screen (fully localized) - Sign Up screen (fully localized) - Dashboard with quick access to all features - Settings screen with language switcher - Navigation system with conditional routing - Kurdistan flag colors throughout (Kesk/Sor/Zer/Spi/Reş) 📱 SCREENS: - WelcomeScreen.tsx - Language selection with 6 options - SignInScreen.tsx - Email/password login - SignUpScreen.tsx - Registration with validation - DashboardScreen.tsx - Main hub with balance, stats, quick actions - SettingsScreen.tsx - Language change, theme, security, logout 🛠 TECH STACK: - React Native + Expo (TypeScript) - react-i18next for translations - @react-native-async-storage/async-storage for persistence - @react-navigation/native for navigation - expo-linear-gradient for beautiful gradients - Custom Kurdistan color system 🎨 UI/UX: - Professional, modern design - Kurdistan flag colors consistently used - Smooth transitions and animations - Responsive layouts - Beautiful gradients and shadows 📂 STRUCTURE: - src/i18n/ - i18n config + 6 language JSON files - src/screens/ - All app screens - src/navigation/ - Navigation logic - src/contexts/ - Language context with AsyncStorage - src/theme/ - Kurdistan colors - App.tsx - Main entry with i18n initialization ✨ USER FLOW: 1. App starts → Welcome screen 2. User selects language → Saved to AsyncStorage 3. User signs in/up → Language follows through 4. Dashboard loads → Everything in selected language 5. User can change language in Settings anytime This is a production-ready mobile app foundation with world-class internationalization. Every single text element adapts to user's chosen language. Perfect execution of the requirement: "user selects language once, entire app uses that language forever (until they change it in settings)".
