[Flutter] Why is the group list empty even though this contact is a member of a group?

I have grouped the contacts, but when I run the print() command in the console, the list of groups is empty. Why is the group list empty even though this contact is a member of a group?



import 'package:flutter/material.dart';
import 'package:flutter_contacts/contact.dart';
import 'package:flutter_contacts/flutter_contacts.dart';

class ContactsPage extends StatefulWidget {
const ContactsPage({super.key});

@override
State<ContactsPage> createState() => _ContactsPageState();
}

class _ContactsPageState extends State<ContactsPage> {
List<Contact> _contacts =[];

@override
void initState() {
super.initState();
_fetchContacts();
}

Future _fetchContacts() async {
if (!await FlutterContacts.requestPermission()) {
} else {
List<Contact> contacts = await FlutterContacts.getContacts();
setState(() => _contacts = contacts);
print(_contacts);
}
return _contacts;
}


@override
Widget build(BuildContext context) {
return Scaffold(
body: FutureBuilder(
future: _fetchContacts(),
builder: (BuildContext context, index) {
return ListView.builder(
itemCount: _contacts.length,
itemBuilder: (BuildContext context, int index) {
return ListTile(
title: Text(_contacts[index].groups[0].name),
);
}, );
},),
);
}
}


console result:

I/flutter ( 9205): [Contact(id=253, displayName=A. H pahlozadeh, thumbnail=null, photo=null, isStarred=true, name=Name(first=, last=, middle=, prefix=, suffix=, nickname=, firstPhonetic=, lastPhonetic=, middlePhonetic=), phones=[], emails=[], addresses=[], organizations=[], websites=[], socialMedias=[], events=[], notes=[], accounts=[], groups=[])
