Whatsapp bot flutter web

Run Whatsapp bot on web natively (within browser without puppeteer)

Getting Started

This library is part of whatsapp_bot_flutter web implementation

Add this script tag in web/index.html file inside of head tag

<script src="./assets/packages/whatsapp_bot_flutter_web/assets/wp_bot.js" defer></script>

Install WhatsappBotFlutter extension on chrome, this extension will insert some required js code in whatsapp web which is required for communication

Install using scripty, To install with scripty, open the link and search for WhatsappBotFlutterCommunicator and install it, that's it this will automatically inject required js in whatsappWeb whenever needed

Or use any extension to inject this code in whatsapp web

const script = document.createElement("script");
script.type = "text/javascript";
script.src = 'https://cdn.jsdelivr.net/gh/rohitsangwan01/whatsapp_bot_flutter_chrome_extension@latest/content.js';
document.body.appendChild(script);

Or manually install extension from here

Usage

Run project using : flutter run -d web-server --web-port 8000 --web-hostname 0.0.0.0, to open in chrome browser where extension is installed

First we have to get WhatsappClient using WhatsappBotFlutterWeb.connect() method

Either link with QRCode (default) and get QrCode in onQrCode callback or set linkWithPhoneNumber, and get code in onPhoneLinkCode callback

WhatsappClient? whatsappClient = await WhatsappBotFlutterWeb.connect({
  onConnectionEvent: (ConnectionEvent event) {
    print(event.toString());
  },
  onQrCode: (String qr, Uint8List? imageBytes) {
    // use imageBytes to display in flutter : Image.memory(imageBytes)
    print(WhatsappBotFlutter.convertStringToQrCode(qr));
  },
});
