cannot send SMS while in background

[GokulakrishnanV]

This is my code:
print("Handling a background message: ${message.messageId}"); print('Message data: ${message.data}'); String mobile = message.data['mobile_numbers']; FCM.mobile = mobile.split(','); FCM.message = message.data['message']; await sendSMS(message: FCM.message, recipients: FCM.mobile, sendDirect: true);

and the error is:

[cherlow]

Did you figure this out? Am having the same problem.

[GokulakrishnanV]

Yes, It was a permission issue. Resolved.

Am having the same problem. What permission should I add or what should I change in the permissions?

Can you share what the permission issue was? Thanks.
