A Flutter-based mobile application designed for seamless and intuitive text translation. This application allows users to translate text between a wide variety of languages, featuring a clean user interface with support for both light and dark themes.

• Real-time Text Translation: Utilizes the translator package (leveraging Google Translate) for accurate and fast translations.
• Multi-language Support:
  • Loads an extensive list of supported and target languages from a local JSON configuration (assets/lang.json).
  • Includes an "Auto Detect" feature for the source language.
• Dual Theme System:
  • Offers both light and dark themes for user preference.
  • Theme selection is persisted across app sessions using SharedPreferences.
  • Custom-defined ThemeData for a polished look and feel in both modes.
• User-Friendly Interface:
  • Introduction Page: Welcomes users with the app logo, a brief description, and easy navigation to the translation screen.
  • Translation Page: Provides intuitive controls for language selection, text input, and viewing translated output.
  • Visual feedback for loading states and error messages.
• Custom Styling: Incorporates Google Fonts for enhanced typography.
• Error Handling: Implements mechanisms to manage and display errors during translation or language data loading.

• Language Service (LanguageService): Manages the loading and caching of language lists from assets/lang.json, optimizing performance.
• Theme Management (_MyTranslatorAppState): Handles theme state, persistence, and toggling logic.
• UI Widgets:
  • MyTranslatorApp: The root widget, setting up MaterialApp and theme configurations.
  • IntroductionPage: The initial landing screen.
  • TranslationPage: The primary interface for all translation tasks.
  • AppFooter: A consistent footer element.

• Flutter: For cross-platform mobile application development.
• Dart: The programming language for Flutter.
• Packages:
  • translator: For core translation functionality.
  • shared_preferences: For persisting theme preferences.
  • google_fonts: For custom font integration.
  • flutter/services (rootBundle): For loading local asset files (e.g., lang.json).

• Flutter SDK: Installation Guide
• An IDE like Android Studio or VS Code with Flutter plugins.
