SMS Scheduling ??

[PranavMasekar]

final sender = SmsSender();
final contacts = ContactQuery();
final contact = await contacts.queryContact('+91xxxxxxxxxx');
log(contact!.fullName.toString());
await sender.sendSms(
SmsMessage(
    contact.address,
    'From Someone',
  ),
);

In the SmsMessage class there are options for date and dataSent.
So does this allows us to schedule messages ?? If not then what exactly are they used for?
