Flutter plugin to read, create, update, delete and observe native contacts on Android and iOS.

For a minimalistic example, take a look at example/. You can write a full-fledged contacts app with it – see example_full/ to see how.

Features #

  • Fetch all contacts
  • Create new contact
  • Update existing contact
  • Delete contacts
  • Observe contact database changes
  • Fetch all details for a given contact, including:
    • Photo (low / high resolution)
    • Phones
    • Emails
    • Company / job title
    • Postal addresses
    • Websites
    • Birthday / events
    • Instant messaging / social profiles
    • Notes
    • Labels (such as "main" or "work" for phones)

★ Exclusive flutter_contacts features:

  • Maximum compability with native contacts: fetching a contact and saving it back doesn't alter it
  • Contacts correctly sorted, ignoring case and diacritics
  • No "zombie contacts" on Android (fake or duplicate contacts that wouldn't appear in your default contact app)
  • Phone numbers and emails deduplicated by default

Usage #

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

if (await Permission.contacts.request().isGranted) {
    /// Get all contacts (IDs and names only)
    List<Contact> contacts = await FlutterContacts.getContacts();

    /// Get all fields (phones, emails, photo, job, etc) for a given contact
    Contact contact = await FlutterContacts.getContact(contacts.first.id);

    /// Listen to contacts database changes
    FlutterContacts.onChange(() => print('Contact DB changed'));

    /// Create contact
    Contact newContact = Contact.create()
        ..name = Name(first: 'John', last: 'Doe')
        ..phones = [Phone('555-123-4567'), Phone('555-999-9999', label: PhoneLabel.work)];
    newContact = await FlutterContacts.newContact(newContact);

    /// Update contact
    newContact.emails.add(Email('john.doe@example.com'));
    await FlutterContacts.updateContact(newContact);

    /// Delete contact
    await FlutterContacts.deleteContact(newContact.id);
}

Data model #

Essential data model (enough for most use cases) #

class Contact {
    String id;
    String displayName;
    Uint8List photo;
    Name name;
    List<Phone> phones;
    List<Email> emails;
    List<Address> addresses;
}

class Name {
    String first;
    String last;
}

class Phone {
    String number;
}

class Email {
    String address;
}

class Address {

    //   - getContact()
    //   - getContacts(withPhotos: true, useHighResolutionPhotos: true)
    //   - getFullContacts(withPhotos: true, useHighResolutionPhotos: true)

    List<String> mimetypes;   // list of android mimetypes
}

Default values #

Apart from photo, nothing can be null. String values default to '', boolean values to false, lists to [], DateTime to Jan 1 1970, and enums as indicated above.

Android/iOS availability #

Some fields are only available on iOS, others only on Android. Concretely it means that if, for example, you save a contact with contact.events[0].noYear = true on Android, you will lose that information when fetching it again.

Regarding labels, some are present in both (e.g. PhoneLabel.mobile), others only on one platform (e.g. PhoneLabel.iPhone). If you try, for example, to save a contact with contact.phones[0].label = PhoneLabel.iPhone on Android, it will instead get saved with label = PhoneLabel.custom and customLabel = 'iPhone'.

Installation #

  1. Add json_serializable: ^3.5.0 (or higher) to the dev_dependencies in pubspec.yaml.
  2. Add permission_handler: ^5.0.0+hotfix.3 (or higher) to the dependencies in pubspec.yaml: this is the package that allows you to request contact permissions.
  3. Add the following key/value pair to your app's Info.plist (for iOS):
     <plist version="1.0">
     <dict>
         ...
         <key>NSContactsUsageDescription</key>
         <string>Access contact list</string>
     </dict>
     </plist>
    
  4. Add the following <uses-permissions> tags to your app's AndroidManifest.xml (for Android):
     <manifest xmlns:android="http://schemas.android.com/apk/res/android" ...>
         <uses-permission android:name="android.permission.READ_CONTACTS"/>
         <uses-permission android:name="android.permission.WRITE_CONTACTS"/>
         <application ...>
         ...
