How to send a file to specific contact in whatsapp using url launcher

We can able to send a text message directly to specific contact, but I want to send a file to whatsapp contact using url launcher. How to achieve this in flutter.

Below is my code for sending only message.

String message = "sample text";
String androidURL = "https://wa.me/917390123456/?text=${Uri.parse(message)}";

if(await canLaunchUrl(Uri.parse(URL))){
    await launchUrl(Uri.parse(URL),mode: LaunchMode.externalApplication);
}

This is working fine for sending text message. How to send a file by using the same. Can someone help.

To send a file, you can use the whatsapp://send?file=<file_url>" URL scheme. To send an image, you can use "whatsapp://send?text=&file=<file_url>" and the file format should be in jpeg or png format.

import 'package:url_launcher/url_launcher.dart';

// ...

void _sendFileToWhatsApp() async {
  var phoneNumber = "917390123456";
  var fileUrl = "https://example.com/file.pdf"; // Replace with the URL of the file you want to send
  var url = "whatsapp://send?phone=$phoneNumber&file=$fileUrl";

  if (await canLaunchUrl(url)) {
    await launchUrl(url);
  }
}

check here. Share images or files _image1.path contains path of the file which is shared to the whatsapp. check here whatsapp_share

Future<void> shareFile() async {
await WhatsappShare.shareFile(
  text: 'Whatsapp share text',
  phone: '911234567890',
  filePath: [_image1.path, _image2.path],
);
