How to Open Native Contact Book to Pick Phone Number in Flutter
Introduction
Flutter is an open-source mobile app development framework created by Google. It is used to develop applications for Android and iOS. One of the common requirements in mobile app development is to access the native contact book to pick a phone number. In this article, we will explore how to open the native contact book to pick a phone number in Flutter.
Requirements
To open the native contact book to pick a phone number in Flutter, you need to add the `contactsservice` package to your project. You can add it to your `pubspec.yaml` file by running the command `flutter pub add contactsservice` in your terminal.
Implementation
To open the native contact book to pick a phone number, you can use the `Contact` class provided by the `contacts_service` package. Here is a sample code snippet that demonstrates how to do it:
“`dart
import ‘package:contactsservice/contactsservice.dart’;
import ‘package:flutter/material.dart’;
class ContactBookPage extends StatefulWidget {
@override
ContactBookPageState createState() => ContactBookPageState();
}
class _ContactBookPageState extends State
Iterable
@override
void initState() {
super.initState();
_getContacts();
}
_getContacts() async {
Iterable
setState(() {
_contacts = contacts;
});
}
_openContactBook() async {
Contact contact = await ContactsService.openContactBook();
if (contact != null) {
print(contact.phones.first.value);
}
}
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text(‘Contact Book’),
),
body: Center(
child: ElevatedButton(
child: Text(‘Open Contact Book’),
onPressed: _openContactBook,
),
),
);
