In flutter app i am using Url_launcher dependency to open phone application with content to dial using following function Url_launcher.launch("tel:\*5*250#" ). It does open the application but # symbol is not dialed in there else everything works ok ... Any workaround to include # ???

I found this issue only on Android devices. It works on iOS.

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

So # equals %23

This will work launch('tel:\*5*250\%23');

This answer helped me.

The easiest and safest way is encode the mobile number typed by user and pass it through

Uri.encodeComponent(numberTypedByUser)

Like this.

launch("tel:" + Uri.encodeComponent('*5*250#'));
