When i run the query .getAllSms() i get the error bellow. All the sms permissions is granted. This is my code.

SmsQuery query = new SmsQuery();
List<SmsMessage> messages = await query.getAllSms.catchError((e) {
      print("Sms error: $e");
    });

I get this error:

hi buddy, i think you should import permission_handler

import 'package:permission_handler/permission_handler.dart'; ...

// in the space where the error was thrown, you should ask the permission first to read sms, // checkSelfPermission might mean that u requested for data like the permission was already given var sms = await Permission.sms.status; if (sms.isGranted) { SmsQuery query = new SmsQuery(); List messages = await query.getAllSms.catchError((e) { print("Sms error: $e"); }); }
