Creating a Telegram bot #

In order to create a Telegram bot, you need to talk to @BotFather generating a bot token. Simply follow the instructions.

Usage #

Initialising the bot:

import 'package:teledart/teledart.dart';
import 'package:teledart/telegram.dart';

void main() {
  var BOT_TOKEN = 'YOUR_BOT_TOKEN_FROM_BOT_FATHER';
  final username = (await Telegram(BOT_TOKEN).getMe()).username;
  var teledart = TeleDart(BOT_TOKEN, Event(username!));

  teledart.start()
}

A simple usage example:

teledart.onMessage(keyword: 'Fight for freedom')
    .listen((message) => message.reply('Stand with Hong Kong'));

Using bot commands:

// Long way
teledart.onMessage(entityType: 'bot_command', keyword: 'start')
    .listen((message) => teledart.sendMessage(message.chat.id, 'Hello TeleDart!'));

// Short way (recommended)
teledart.onCommand('glory')
    .listen((message) => message.reply('to Ukraine!'));

Modifying Stream:

teledart
    .onMessage(keyword: 'dart')
    .where((message) => message.text?.contains('telegram') ?? false)
    .listen((message) => message.replyPhoto(
        //  io.File('example/dash_paper_plane.png'),
        'https://raw.githubusercontent.com/DinoLeung/TeleDart/master/example/dash_paper_plane.png',
        caption: 'This is how the Dart Bird and Telegram are met'));

Inline mode example:

teledart.onInlineQuery().listen((inlineQuery) => inlineQuery.answer([
      InlineQueryResultArticle(
          id: 'ping',
          title: 'ping',
          inputMessageContent: InputTextMessageContent(
              messageText: '*pong*', parseMode: 'MarkdownV2')),
      InlineQueryResultArticle(
          id: 'ding',
          title: 'ding',
          inputMessageContent: InputTextMessageContent(
              messageText: '*_dong_*', parseMode: 'MarkdownV2')),
    ]));
