Just a Telegram Library for Dart. A package to interact with the official

Disclaimer #

I'm doing it just for fun, so... use at your own risk.

I hope it will become something great.


Usage #

First build the .g files for Serializable (if you clone the repo):

pub run build_runner build

A simple usage example:

import 'dart:io' as io;
import 'package:paperplane/paperplane.dart';

void main() {
  var token = 'Just A Token';
  var bot = PaperPlane.createBot(token);

  // Work with events...
    .where((message) => message.text == 'owo')
    .listen((message) => message.replyText(text: 'uwu'));
  // Work with updates and directly with methods...
  var api = bot.api;
  var updater = bot.updater.onUpdate();
    .where((onUpdate) => onUpdate.message.text == 'animate')
    .listen((update) => methods.sendAnimation(
      animation: Luggage.withFile(file: io.File('./files/gifs/bunny_girl.gif'))));
