WhatsApp will include your message in <code>text</code> and it will automatically appear in the text field of a chat.</p> <p>Both the <code>phoneNumber</code> and <code>text</code> arguments are optional. The <code>WhatsAppUnilink</code> instance, whenever converted to a string, will create a WhatsApp link for you.</p> <p>When <code>WhatsAppUnilink</code> instance is converted to a string, any brackets, dashes, plus signs, and leading zeros or any other non-digit characters will be removed from the phone number.</p> <p>The APIs support working with strings (<code>toString()</code>) and URIs (<code>asUri</code>).</p> <p><em>Important</em>: the <code>whatsapp_unilink</code> package does not convert from the local phone numbers format to the international format based on the device's locale.</p> <h3 class="hash-header" id="flutter">Flutter <a href="#flutter" class="hash-link">#</a></h3> <p>You may want to launch the WhatsApp app on your user's phone and make life easier for your users by pre-filling the mobile number and text.</p> <p>Use the <a href="https://pub.dev/packages/url_launcher"><code>url_launcher</code></a> for launching the links you create with the <code>whatsapp_unilink</code> package.</p> <pre><code class="language-dart">import 'package:whatsapp_unilink/whatsapp_unilink.dart'; // For Flutter applications, you'll most likely want to use // the url_launcher package. import 'package:url_launcher/url_launcher.dart'; // ...somewhere in your Flutter app... launchWhatsAppUri() async { final link = WhatsAppUnilink( phoneNumber: '+001-(555)1234567', text: "Hey!

You can either explicitly call the <code>link.toString()</code> method, or you may rely on Dart's shorter string interpolation, <code>'$link'</code>.</p> <pre><code class="language-dart">import 'package:url_launcher/url_launcher_string.dart'; launchWhatsAppString() async { final link = WhatsAppUnilink( phoneNumber: '+001-(555)1234567', text: "Hey!
