🏗️ Modular Architecture #

This package is built with a clean, modular architecture that separates different functionalities into focused modules:

Core Modules #

  • url_schemes.dart - Client-side URL scheme methods for direct Telegram app integration
  • messaging.dart - Bot API messaging methods for sending text, formatted messages, and interactive content
  • media.dart - Media handling for photos, videos, audio, documents, stickers, and animations
  • chat.dart - Chat management including information retrieval, settings, and administrative actions
  • members.dart - Member management for user permissions, roles, and moderation
  • bot_config.dart - Bot configuration including commands, descriptions, and profile settings
  • webhook.dart - Webhook management for real-time message handling and bot updates

Unified Interface #

All modules are seamlessly integrated through the main Telegram class, providing a single, comprehensive API while maintaining clean separation of concerns under the hood.

// All methods are available through the main Telegram class
import 'package:telegram/telegram.dart';

// URL scheme methods
await Telegram.send(username: 'user', message: 'Hello');

// Bot API methods  
await Telegram.sendMessage(chatId: 'chat', text: 'Hello');

// Media methods
await Telegram.sendPhoto(chatId: 'chat', photo: 'url');

// Chat management
await Telegram.getChat(chatId: 'chat');

You can also import specific modules if you only need certain functionality:

// Import only what you need
import 'package:telegram/src/messaging.dart';
import 'package:telegram/src/media.dart';

// Use module classes directly
await TelegramMessaging.sendMessage(chatId: 'chat', text: 'Hello');
await TelegramMedia.sendPhoto(chatId: 'chat', photo: 'url');
