• To be able to use v1.0.0+ you will need to add AppGroups capability to your iOS project target.

Supported platforms:

• iOS
• Android

Requirements

• PPG project
• Access to Firebase Console
• Access to Apple Developers console
• For iOS - Cocoapods (or other package manager)

Approximate time of integration (without further implementation): 2-3h

Environment setup

Make sure that you have flutter installed, and flutter doctor command pass.

$ flutter doctor

If pass without any exceptions you are ready to go through next steps

1. Add SDK to your existing application

1.1 Install flutter package

$ flutter pub add pushpushgo_sdk

1.2 Add code to your main.dart file

1.2.1 Import library

import 'package:pushpushgo_sdk/pushpushgo_sdk.dart';

copied to clipboard

1.2.1 Initialize client

Declare and initialize PPG client in your main application class

    final pushpushgo = PushpushgoSdk({
        "apiToken": "my-api-key-from-pushpushgo-app", 
        "projectId": "my-project-id-from-pushpushgo-app"
        "appGroupId": "your-app-group-id-from-provisioning-profile"  // required from v1.0.0+
    });
    
    pushpushgo.initialize(onNewSubscriptionHandler: (subscriberId) {
      log(subscriberId);
    });

Then fill apiToken and projectId by your credentials from PPG project.

Note: If you want to see example of integration on test app visit: https://github.com/ppgco/flutter-example-integration

2. iOS Support

2.1 In Xcode open Podfile in /ios/ folder

Next steps are performed using Cocoapods package manager.

Make sure your minimum deployment platform version is at lest 14.0

Add to target 'Runner' do on the end of declaration:

  pod 'PPG_framework', :git => 'https://github.com/ppgco/ios-sdk.git'

2.2.1 Enable Push Notification Capabilities in Project Target

1. Select your root item in files tree called "your_project_name" with blue icon and select your_project_name in Target section.
2. Go to Signing & Capabilities tab and click on "+ Capability" under tabs.
3. Select Push Notifications, Background Modes and AppGroups (from v1.0.0+)
4. On Background Modes select items:

• Remote notifications
• Background fetch

2.2.2 Add NotificationServiceExtension

1. Go to file -> New -> Target

2. Search for Notification Service Extension and choose product name may be for example NSE

3. Finish process and on prompt about Activate “NSE” scheme? click Cancel

4. Open file NotificationService.swift

5. Paste this code:

   import UserNotifications
   import PPG_framework
   
   class NotificationService: UNNotificationServiceExtension {
   
       var contentHandler: ((UNNotificationContent) -> Void)?
       var bestAttemptContent: UNMutableNotificationContent?
   
       override func didReceive(_ request: UNNotificationRequest, withContentHandler contentHandler: @escaping (UNNotificationContent) -> Void) {
           self.contentHandler = contentHandler
           self.bestAttemptContent = (request.content.mutableCopy() as? UNMutableNotificationContent)
   
           guard let content = bestAttemptContent else { return }
   
           // Wait for delivery event result & image fetch before returning from extension
           let group = DispatchGroup()
           group.enter()
           group.enter()
   
           // Fill your app group id
           SharedData.shared.appGroupId = "YOUR APP GROUP ID" 
   
           PPG.notificationDelivered(notificationRequest: request) { _ in
               group.leave()
           }
   
           DispatchQueue.global().async { [weak self] in
               self?.bestAttemptContent = PPG.modifyNotification(content)
               group.leave()
           }
   
           group.notify(queue: .main) {
               contentHandler(self.bestAttemptContent ?? content)
           }
       }
   
       override func serviceExtensionTimeWillExpire() {
           // Called just before the extension will be terminated by the system.
           // Use this as an opportunity to deliver your "best attempt" at modified content, otherwise the original push payload will be used.
           if let contentHandler = contentHandler, let bestAttemptContent =  bestAttemptContent {
               contentHandler(bestAttemptContent)
           }
       }
   
   }

6. Add NotificationServiceExtension target to Podfile: Use name of file you created - in our case 'NSE'

   target 'NSE' do
     use_frameworks!
     use_modular_headers!
     pod 'PPG_framework', :git => 'https://github.com/ppgco/ios-sdk.git'
   end
   

   copied to clipboard

7. And again navigate to yourFlutterProject/ios/ in terminal and run command:

   $ pod install

8. (optional) In Info.plist add folowing to enable deep linking in flutter

   <key>FlutterDeepLinkingEnabled</key>
   <true/>
   

   copied to clipboard

2.3 Prepare certificates

1. Go to Apple Developer Portal - Identities and go to Identifiers section
2. Select from list your appBundleId like com.example.your_project_name
3. Look for PushNotifications and click "Configure" button
4. Select your Certificate Singing Request file
5. Download Certificates and open in KeyChain Access (double click in macos)
6. Find this certificate in list select then in context menu (right click) select export and export to .p12 format file with password.
7. Login into app and add this Certificate.p12 file with password via UI (https://next.pushpushgo.com/projects/YourProjectID/settings/integration/fcm)

import io.flutter.embedding.android.FlutterActivity

class MainActivity: FlutterActivity() {

    @RequiresApi(api = Build.VERSION_CODES.TIRAMISU)
    private fun requestNotificationsPermission() {
        if (ActivityCompat.checkSelfPermission(
                this,
                Manifest.permission.POST_NOTIFICATIONS
            ) != PackageManager.PERMISSION_GRANTED
