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.
