I want to Save Contact Number at Mobile storage using Flutter - flutter

Question

I wrote this function to save contact number, but it can't save on local storage
Future _saveContact() async {
Contact contact = Contact();
contact.familyName = 'FreeZone';
contact.phones = [Item(label: "mobile", value: '01752591591')];
contact.emails = [Item(label: "work", value: 'info#34.71.214.132')];
if (await Permission.contacts.request().isGranted) {
await ContactsService.addContact(contact);
print("Contact added successfully");
return contact;
}
}
dependencies:
contacts_service: ^0.6.3
permission_handler: ^8.3.0
How to save contact according to the above-given Name, Number, Email?

Answer 1

I could see 2 plugins in pub.dev that can do this for you in Android and iOS.
flutter_contact - A Flutter plugin to retrieve, create and save contacts and contact-related events on Android and iOS devices.
contacts_service - A Flutter plugin to retrieve and manage contacts on Android and iOS devices.
Please have a look into them.

Answer 2

Add this :
dependencies:
contacts_service: ^0.6.3
then:
import 'package:contacts_service_example/contacts_list_page.dart';
import 'package:contacts_service_example/contacts_picker_page.dart';
import 'package:flutter/material.dart';
import 'package:permission_handler/permission_handler.dart';
void main() => runApp(ContactsExampleApp());
// iOS only: Localized labels language setting is equal to CFBundleDevelopmentRegion value (Info.plist) of the iOS project
// Set iOSLocalizedLabels=false if you always want english labels whatever is the CFBundleDevelopmentRegion value.
const iOSLocalizedLabels = false;
class ContactsExampleApp extends StatelessWidget {
#override
Widget build(BuildContext context) {
return MaterialApp(
home: HomePage(),
routes: <String, WidgetBuilder>{
'/add': (BuildContext context) => AddContactPage(),
'/contactsList': (BuildContext context) => ContactListPage(),
'/nativeContactPicker': (BuildContext context) => ContactPickerPage(),
},
);
}
}
class HomePage extends StatefulWidget {
#override
_HomePageState createState() => _HomePageState();
}
class _HomePageState extends State<HomePage> {
#override
void initState() {
super.initState();
_askPermissions(null);
}
Future<void> _askPermissions(String routeName) async {
PermissionStatus permissionStatus = await _getContactPermission();
if (permissionStatus == PermissionStatus.granted) {
if (routeName != null) {
Navigator.of(context).pushNamed(routeName);
}
} else {
_handleInvalidPermissions(permissionStatus);
}
}
Future<PermissionStatus> _getContactPermission() async {
PermissionStatus permission = await Permission.contacts.status;
if (permission != PermissionStatus.granted &&
permission != PermissionStatus.permanentlyDenied) {
PermissionStatus permissionStatus = await Permission.contacts.request();
return permissionStatus;
} else {
return permission;
}
}
void _handleInvalidPermissions(PermissionStatus permissionStatus) {
if (permissionStatus == PermissionStatus.denied) {
final snackBar = SnackBar(content: Text('Access to contact data denied'));
ScaffoldMessenger.of(context).showSnackBar(snackBar);
} else if (permissionStatus == PermissionStatus.permanentlyDenied) {
final snackBar =
SnackBar(content: Text('Contact data not available on device'));
ScaffoldMessenger.of(context).showSnackBar(snackBar);
}
}
#override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(title: const Text('Contacts Plugin Example')),
body: SafeArea(
child: Column(
crossAxisAlignment: CrossAxisAlignment.stretch,
children: <Widget>[
ElevatedButton(
child: const Text('Contacts list'),
onPressed: () => _askPermissions('/contactsList'),
),
ElevatedButton(
child: const Text('Native Contacts picker'),
onPressed: () => _askPermissions('/nativeContactPicker'),
),
],
),
),
);
}
}

I think I solved your problem.
_saveContact () async {
// 'without Future' is working
var newPerson = Contact();
// newPerson uses Contact Package
newPerson.givenName = 'FreeZone';
newPerson.phones = [Item(label: "mobile", value: '01752591591')];
newPerson.emails = [Item(label: "work", value: 'info#34.71.214.132')];
if (await Permission.contacts.status.isGranted) {
await ContactsService.addContact(newPerson);
var contacts = await ContactsService.getContacts();
print("Contact added successfully");
return contacts;
// setState(() {
// //setState isn't necessary, it just shows 'contact' directly on a screen.
// name = contacts;
// // I put 'contacts' in 'name' directly
// });
}
}
Actually, I was in trouble using 'newPerson.phones'.
I was wondering how to put my parameter in 'phone number'.
However, with your code, I could know how to write the code.
Thank you and please accept this answer as a small token of my appreciation.
And it is what I wrote you helped.
addPerson (given,family,number) async {
var newPerson = Contact();
newPerson.givenName = given;
newPerson.familyName = family;
newPerson.phones = [Item(label: "mobile", value: number)];
// I wrote 'newPerson.phones = [number];' and it was wrong.
await ContactsService.addContact(newPerson);
// adding newPerson
var contacts = await ContactsService.getContacts();
// call all of contacts
setState(() {
name = contacts;
});
// to show the contacts directly, I use 'setState'.
}
