    Uri dataUrl = Uri.parse(url!);

    if (await canLaunchUrl(dataUrl)) {

      throw 'Could not launch $dataUrl';
    }
  }

  static launchWhatsApp(

    String url = '';
    if (Platform.isAndroid) {
      url = "https://wa.me/$phone?text=${Uri.parse(message)}";

    The url in my case that works, looks like this. Try this:

    https://wa.me/${phone}/?text=hello

    Maybe this can help you:

    import 'package:whatsapp_unilink/whatsapp_unilink.dart';
import 'package:url_launcher/url_launcher.dart';

        final link = WhatsAppUnilink(
          phoneNumber: '+000000000',
          text: "hello",
        );
    
        await launch('$link');
