使用插件。

https://pub.dev/packages/url_launcher

final url = "https://wa.me/91XXXXXXXXXX?text=Hello";

//do not forgot to enter your country code instead of 91 and instead of XXXXXXXXXX enter phone number.

if (await canLaunchUrl(Uri.parse(url))) {
  await launchUrl(Uri.parse(url));
} else {
  showSnackBar(message: "Can't share link", title: "Error");
}
if (!await launchUrl(Uri.parse(url))) throw 'Could not launch $url';
