I am trying to send sms in trial version but facing Unhandled Exception: Exception

[irfansadiq786]

I am using this plugin for sending sms in trial version. Whenever I try to send sms to different number other than I added in console, I got an exception which I am unable to handle, I tried wrapping with try, catch block of My code when sending sms so i can catch the exception but failed. Whenever I call twilioFlutter.sendSMS method I got an exception and my app crashes. Here is my Code: try { twilioFlutter.sendSMS( toNumber: phoneNumber, messageBody: 'Irfan Sadiq is sending message and your code is $otp'); } catch (e) { ScaffoldMessenger.of(context) .showSnackBar(const SnackBar(content: Text('Something went wrong'))); } Any help, fixes will be highly appreciated. Thanks
