Push Messaging
Send targeted push notifications to your Flutter app users with Antsomi SDK. Rich media support & iOS/Android integration guide.
Antsomi's App Push feature empowers you to deliver impactful notifications to your mobile app users, fostering effective engagement and communication. These push notifications provide a dynamic avenue for timely, personalized, and efficient information delivery, enhancing user interactions with your mobile application.
Before continuing, please ensure that you've added the Flutter SDK to your app.
For Android
For Android integration, you'll need to ensure you have the correct Application ID. Once you have it, provide it in the Antsomi SDK configuration and we will handle the rest for you.
import 'dart:io' show Platform;
import 'package:antsomisdk/antsomi.dart'; // Contains Antsomi SDK APIs
if (Platform.isAndroid) {
AntsomiSDK.instance.config(
appGroupId: 'group.antsomi.mstore',
portalId: '564890637',
propsId: '564993464',
applicationID: 'e4e8d06e-4d97-43df-93e8-c36238147ca0',
);
}
If you're unsure how to obtain it, kindly follow these instructions.
For iOS
For iOS integration, you'll need to create a Notification Service Extension and ensure it's part of the same app group as your Flutter app. Then, provide the App Group ID to the Antsomi SDK during the integration process.
iOS development requires an iOS 11+ device (iPhone, iPad, iPod Touch) for testing.
You can also use the Xcode 14+ simulator with iOS 16+ to replicate your app environment.
Step 1: Add an iOS Service Extension
The AntsomiNotificationService
enables your iOS app to receive feature-rich notifications, including images, buttons, and badges.
1.1: Within your project's iOS folder, open the .xcworkspace
file in Xcode.
1.2: Select File
> New
> Target
1.3: Select Notification Service Extension
and press Next

Notification Service Enxtension
1.4: Provide the Extension Name (e.g., NotificationExtension
) and select the Swift
language (Objective-C
is also acceptable if needed).
1.5: Then click Finish
. Do not select Activate
on the dialog shown after selecting Finish
.
1.6: To maintain Xcode in debugging mode for your app rather than the extension, please click Cancel
when prompted to activate the scheme.
If you selected Activate
by accident, you can simply switch back to debug your app in Xcode (next to the Play button).

1.7: Open the project with Xcode, in the Project Navigator, select the top-level project directory and select the NotificationExtension
target.
Make sure that the Deployment Target
is configured to match the value of your Main Application Target
. Unless you have a particular reason to do otherwise, we recommend setting the Deployment Target
to iOS 10. This version of iOS is essential for accessing Rich Media in push notifications. Note that iOS versions older than 10 will not support Rich Media.

Step 2: Update the Flutter project
2.1: Close the Xcode project. In the /ios
directory of your Flutter project, open the Podfile, and add the following outside of the main target (should be at the same level as your main target):
#Add this to notification extension
target 'NotificationExtension' do
use_frameworks!
use_modular_headers!
pod 'AntsomiFramework', '0.0.9'
end
Your final Podfile will be similar to below:
### THIS IS EXAMPLE POD FILE ###
# Uncomment this line to define a global platform for your project
platform :ios, '11.0'
# CocoaPods analytics sends network stats synchronously affecting flutter build latency.
ENV['COCOAPODS_DISABLE_STATS'] = 'true'
project 'Runner', {
'Debug' => :debug,
'Profile' => :release,
'Release' => :release,
}
def flutter_root
generated_xcode_build_settings_path = File.expand_path(File.join('..', 'Flutter', 'Generated.xcconfig'), __FILE__)
unless File.exist?(generated_xcode_build_settings_path)
raise "#{generated_xcode_build_settings_path} must exist. If you're running pod install manually, make sure flutter pub get is executed first"
end
File.foreach(generated_xcode_build_settings_path) do |line|
matches = line.match(/FLUTTER_ROOT\=(.*)/)
return matches[1].strip if matches
end
raise "FLUTTER_ROOT not found in #{generated_xcode_build_settings_path}. Try deleting Generated.xcconfig, then run flutter pub get"
end
require File.expand_path(File.join('packages', 'flutter_tools', 'bin', 'podhelper'), flutter_root)
flutter_ios_podfile_setup
target 'Runner' do
use_frameworks!
use_modular_headers!
flutter_install_all_ios_pods File.dirname(File.realpath(__FILE__))
target 'RunnerTests' do
inherit! :search_paths
end
end
### Add SDK for extension target here
target 'NotificationExtension' do
use_frameworks!
use_modular_headers!
pod 'AntsomiFramework', '0.0.9'
end
###
post_install do |installer|
installer.pods_project.targets.each do |target|
flutter_additional_ios_build_settings(target)
end
end
2.2: Open the terminal, in the ios
directory, and run pod install
.
2.3: Open the <project-name>.xcworkspace
file (Make sure you open the .xcworkspace file).
In your project, at the NotificationExtension
folder, navigate to NotificationService
and modify the code like below:
import Foundation
import UserNotifications
import AntsomiFramework
class NotificationService: AntsomiNotificationService {
var contentHandler: ((UNNotificationContent) -> Void)?
var bestAttemptContent: UNMutableNotificationContent?
override func didReceive(_ request: UNNotificationRequest, withContentHandler contentHandler: @escaping (UNNotificationContent) -> Void) {
self.contentHandler = contentHandler
bestAttemptContent = (request.content.mutableCopy() as? UNMutableNotificationContent)
super.didReceive(request, withContentHandler: contentHandler)
}
}
Step 3: Enable iOS Push Capability in Xcode
3.1: In the main app target, select Signing & Capabilities
> All
> + Capability
, enable Push Notifications
.

Signing & Capabilities
3.2: Enable Background Modes
and check Remote Notifications
.

Background Modes
Step 4: Add App Group to your app
1.1 Go to your main app target, select Signing & Capabilities
> All
> + Capability
, search for App Group

4.2: Under App Groups click the +
button
4.3: Set the App Groups container identifier.
4.4: Go to the NotificationExtension
Target, select Signing & Capabilities
> All
> + Capability
, search for App Group, and add App Group to your NotificationExtension
target.
Make sure the NotificationServiceExtension
and your app have the same App Group ID.

Finally, you can go back to the integration process to continue initing the Anstomi SDK
