Question

I am using the url_launcher plugin for call, but the dialer is not showing the # character:

String url = \'tel:*123#\';
if (await canLa         


        

Answer 1

You need to use URL encoding for special character in a URL.

So # equals %23

This will work launch('tel:\*123\%23');

Other Way is to encode the number typed by user and pass it through Uri.encodeFull(urlString) or Uri.encodeComponent(urlString)

Like this.

launch("tel:" + Uri.encodeComponent('*123#'));
