TeleDart #
A clean implementation of Telegram bot API allows you to create your own easily.

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()
}
