Flutter plugin to retrieve and manage contacts on Android

A Flutter plugin to retrieve and manage contacts on Android and iOS devices.

A Flutter plugin to access and manage the device’s contacts.

Usage

To use this plugin, add contacts_service as a dependency in your pubspec.yaml file.
For example:

dependencies:  
    contacts_service: ^0.4.6

Permissions

Android

Add the following permissions to your AndroidManifest.xml:

<uses-permission android:name="android.permission.READ_CONTACTS" />  
<uses-permission android:name="android.permission.WRITE_CONTACTS" />  

iOS

Set the NSContactsUsageDescription in your Info.plist file

<key>NSContactsUsageDescription</key>  
<string>This app requires contacts access to function properly.</string>  

Note
contacts_service does not handle the process of asking and checking for permissions. To check and request user permission to access contacts, try using the following plugins: flutter_simple_permissions or permission_handler.

If you do not request user permission or have it granted, the application will fail. For testing purposes, you can manually set the permissions for your test app in Settings for your app on the device that you are using. For Android, go to “Settings” – “Apps” – select your test app – “Permissions” – then turn “on” the slider for contacts.

Example

// Import package  
import 'package:contacts_service/contacts_service.dart';  
  
// Get all contacts on device
Iterable<Contact> contacts = await ContactsService.getContacts();  

// Get all contacts without thumbnail (faster)
Iterable<Contact> contacts = await ContactsService.getContacts(withThumbnails: false);

// Android only: Get thumbnail for an avatar afterwards (only necessary if `withThumbnails: false` is used)
Uint8List avatar = await ContactsService.getAvatar(contact);
  
// Get contacts matching a string
Iterable<Contact> johns = await ContactsService.getContacts(query : "john");

// Add a contact  
// The contact must have a firstName / lastName to be successfully added  
await ContactsService.addContact(newContact);  
  
// Delete a contact
// The contact must have a valid identifier
await ContactsService.deleteContact(contact);  

// Update a contact
// The contact must have a valid identifier
await ContactsService.updateContact(contact);

// Usage of the native device form for creating a Contact
// Throws a error if the Form could not be open or the Operation is canceled by the User
await ContactsService.openContactForm();

// Usage of the native device form for editing a Contact
// The contact must have a valid identifier
// Throws a error if the Form could not be open or the Operation is canceled by the User
await ContactsService.openExistingContact(contact);
