android无需额外配置
ios:

需要 url_launcher

_launchWhatsapp() async {
//直接对指定号码发送消息
// 参考: https://api.whatsapp.com/send?phone=$phone&text=${URLEncoder.encode(message, "UTF-8")}
//  const url = 'whatsapp://send?phone=$phone';
const url = "https://wa.me/?text=Your Message here";
var encoded = Uri.encodeFull(url);

if (await canLaunch(encoded )) {
  await launch(encoded );
