Cant Add Contacts

Your add contact example is one line, with no guide on how to initialize the contact.

Looking at the source, I think my below code should work, but it fails with below error. Any idea on how I’m doing wrong?

(Tried on Android 9 && Android 8)

Code:

import 'package:contacts_service/contacts_service.dart';
import 'dart:async';

Future<void> generateContact(String name, String phone) async {
    Item phoneNumber = Item.fromMap({
      "label": "mobile",
      "phone": phone
    });
    await ContactsService.addContact(Contact(phones: [phoneNumber], givenName: name, familyName: "SOME DATA"));
}

Error:

As @clovisnicolas mention, you should handle Permission.WriteContacts permission before adding a new contact, using flutter_simple_permissions plugin:

bool isPermissionGranted = await SimplePermissions.checkPermission(Permission.WriteContacts);

Can you try this plugin https://github.com/Ethras/flutter_simple_permissions And ask for permissions before adding/fetching contacts ?
