Thanks to rohitsangwan01 for reference!

Getting Started

In the pubspec.yaml of your flutter project, add the following dependency:

dependencies:
  ...
  whatsapp_sender_flutter: latest

Import it:

import 'package:whatsapp_sender_flutter/whatsapp_sender_flutter.dart';

Configuration

For the first usage, wait for the automatic download of the .local-chromium folder in your project root. Without this folder the package will not work,this is because this package is based on puppeteer.

Basic usage

The process for sending messages is like for WhatsApp Web:

1. Scan the qr code
2. Start the sending

Send text message

After you have scanned the code, you can start the sending campaign.

All phones must contain the international prefix!

   ...
   await WhatsAppSenderFlutter.send(
         phones: [ "391111111", "391111111", "391111111"],
         message: "Hello",
   );

Send file message

After you have scanned the code, you can start the sending campaign.

All phones must contain the international prefix!

   await WhatsAppSenderFlutter.send(
         phones: [ "391111111", "391111111", "391111111"],
         message: "Hello",
         file: File("path-to-file.pdf"),
   );

Listen changes

New functions for listen changes:

1. onEvent(WhatsAppSenderFlutterStatus status), usethis function to listen the sending status
2. onQrCode(String qrCode), use this function to intercept the qrCode
3. onSending(WhatsAppSenderFlutterCounter counter), use this function to count the number of successful or unsuccessful submissions.
4. onError(WhatsAppSenderFlutterErrorMessage errorMessage), use this feature to catch errors while sending

   ...
   await WhatsAppSenderFlutter.send(
        phones: [ "391111111", "391111111", "391111111"],
        message: "Hello",
        file: File("path-to-file.pdf"),
        onEvent: (WhatsAppSenderFlutterStatus status) {
          print(status);
        },
        onQrCode: (String qrCode) {
          print(qrCode);
        },
        onSending: (WhatsAppSenderFlutterCounter counter) {
          print(counter.success.toString());
          print(counter.fails.toString());
        },
        onError: (WhatsAppSenderFlutterErrorMessage errorMessage) {
          print(errorMessage);
        },
   );

To know in detail the possible states of WhatsAppSenderFlutterStatus, WhatsAppSenderFlutterCounter, WhatsAppSenderFlutterErrorMessage read documentation

Save your session

   WhatsAppSenderFlutter whatsAppSenderFlutter = WhatsAppSenderFlutter();
   ...
   await whatsAppSenderFlutter.send(
         phones: [ "391111111", "391111111", "391111111"],
         message: "Hello",
         savedSessionDir: "./userData"
   );

To save the session you must indicate a folder name in savedSessionDir.

If you save the session you will no longer have to scan the qr code !

Do not indicate savedSessionDir if you want to be asked to scan the qr code at each sending.

To Do

• Send text message ✔️
• Multi session support ✔️
• Send files ✔️
