Flutter VoIP Push Notification #

pub package Flutter VoIP Push Notification - Currently iOS >= 8.0 only

Motivation #

Since iOS 8.0 there is an execellent feature called VoIP Push Notification (PushKit), while firebase_messaging does not support voip push notification which is only available on iOS >= 8.0 which is the reason for this plugin.

To understand the benefits of Voip Push Notification, please see VoIP Best Practices.

Note 1: This plugin works for only iOS. You can use firebase_messaging for Android by sending high priority push notification

Note 2 This This plugin was inspired by react-native-voip-push-notification and firebase_messaging

iOS #

The iOS version should be >= 8.0 since we are using PushKit.

Enable VoIP Push Notification and Get VoIP Certificate #

Please refer to VoIP Best Practices.

Note: Do NOT follow the Configure VoIP Push Notification part from the above link, use the instruction below instead.

Usage #

Add flutter_voip_push_notification as a dependency in your pubspec.yaml file.

Example #

import 'package:flutter/material.dart';
import 'package:flutter/material.dart';
import 'dart:async';
import 'package:flutter_voip_push_notification/flutter_voip_push_notification.dart';

void main() => runApp(MyApp());

class MyApp extends StatefulWidget {
  _MyAppState createState() => _MyAppState();

class _MyAppState extends State<MyApp> {
  String _pushToken = '';
  FlutterVoipPushNotification _voipPush = FlutterVoipPushNotification();
  void initState() {

  // Configures a voip push notification
  Future<void> configure() async {
    // request permission (required)
    await _voipPush.requestNotificationPermissions();

    // listen to voip device token changes

    // do configure voip push
    _voipPush.configure(onMessage: onMessage, onResume: onResume);

  /// Called when the device token changes
  void onToken(String token) {
    // send token to your apn provider server
    setState(() {
      _pushToken = token;

  /// Called to receive notification when app is in foreground
  /// [isLocal] is true if its a local notification or false otherwise (remote notification)
  /// [payload] the notification payload to be processed. use this to present a local notification
  Future<dynamic> onMessage(bool isLocal, Map<String, dynamic> payload) {
    // handle foreground notification
    print("received on foreground payload: $payload, isLocal=$isLocal");
    return null;

  /// Called to receive notification when app is resuming from background
  /// [isLocal] is true if its a local notification or false otherwise (remote notification)
  /// [payload] the notification payload to be processed. use this to present a local notification
  Future<dynamic> onResume(bool isLocal, Map<String, dynamic> payload) {
    // handle background notification
    print("received on background payload: $payload, isLocal=$isLocal");
    return null;

  showLocalNotification(Map<String, dynamic> notification) {
    String alert = notification["aps"]["alert"];
      alertBody: "Hello $alert",

  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: const Text('Plugin example app'),
