requestSmsPermission method

Implementation

Future<void> requestSmsPermission() async {
  await Permission.sms.request();
  var status = await Permission.sms.status;
  if (status.isDenied) {
    // We didn't ask for permission yet or the permission has been denied before but not permanently.

  }

// You can can also directly ask the permission about its status.
  if (await Permission.location.isRestricted) {
    // The OS restricts access, for example because of parental controls.
  }
}
