Configuración del SDK de Flutterflow

​

Requisitos

• Plan Flutterflow: Standard o superior
• Aplicación y plataforma de OneSignal configuradas

• macOS con Xcode 14+ (las instrucciones de configuración usan Xcode 16.2)
• Dispositivo con iOS 12+, iPadOS 12+ o simulador de Xcode ejecutando iOS 16.2+
• CocoaPods 1.16.2+

• Dispositivo Android 7.0+ o emulador con Google Play Store (Services) instalado

​

Configure your OneSignal app and platform

Step-by-step setup instructions

1

Create or select your app

Create a new app by clicking New App/Website, or add a platform to an existing app in Settings > Push & In-App. Select the platform(s) you want to configure and click Next: Configure Your Platform.

2

Configure platform credentials

Enter the credentials for your platform:

• Android: Set up Firebase credentials
• iOS: p8 token (recommended) or p12 certificate
• Amazon: Generate API key
• Huawei: Authorize OneSignal

Click Save & Continue after entering your credentials.

3

Save your App ID and install the SDK

Your App ID is displayed on the final screen. Copy and save it — you need it when initializing the SDK. Select your SDK platform, then follow the setup guide.

​

Configuración

​

1. Crear una nueva acción personalizada

  dependencies:
  	onesignal_flutter: ^5.1.2

  import 'package:onesignal_flutter/onesignal_flutter.dart';

  Future onesignal() async {
    //Remove this method to stop OneSignal Debugging
    OneSignal.Debug.setLogLevel(OSLogLevel.verbose);

    OneSignal.initialize("YOUR_APP_ID");

    // The promptForPushNotificationsWithUserResponse function will show the iOS or Android push notification prompt. We recommend removing the following code and instead using an In-App Message to prompt for notification permission
    OneSignal.Notifications.requestPermission(true);
  }

​

2. Exportar el proyecto

• Descarga de APK (solo Android)
• Descarga de proyecto completo (iOS y Android)

Abre el Developer Menu y descarga el APK:

Una vez que el APK se haya descargado, puedes probar la aplicación arrastrando el APK a un emulador Android para instalarlo. Las capacidades push deberían funcionar de inmediato y puedes enviar notificaciones push al dispositivo tan pronto como proporciones permisos push a través del prompt nativo.

Abre el Developer Menu y descarga el código del proyecto:

​

3. Configuración de iOS

• Abre una ventana de Terminal, cd (cambiar directorio) a la carpeta ios de tu proyecto descargado.
• En Terminal escribe flutter build ios y presiona enter. Espera a que la compilación se complete, esto puede tomar algún tiempo dependiendo del tamaño de tu proyecto.
• Todavía en Terminal escribe pod install y presiona enter. Espera a que la instalación del pod se complete.

​

Agregar Notification Service Extension

​

Agregar App Groups

​

Agregar SDK de OneSignal a la OneSignalNotificationServiceExtension

target 'OneSignalNotificationServiceExtension' do
  pod 'OneSignalXCFramework', '>= 5.0.0', '< 6.0'
end

# Uncomment this line to define a global platform for your project
platform :ios, '11.0'

- Runner (true) and OneSignalNotificationServiceExtension (false) do not both set use_frameworks!.

​

Código de OneSignalNotificationServiceExtension

import UserNotifications

import OneSignalExtension

class NotificationService: UNNotificationServiceExtension {

    var contentHandler: ((UNNotificationContent) -> Void)?
    var receivedRequest: UNNotificationRequest!
    var bestAttemptContent: UNMutableNotificationContent?

    override func didReceive(_ request: UNNotificationRequest, withContentHandler contentHandler: @escaping (UNNotificationContent) -> Void) {
        self.receivedRequest = request
        self.contentHandler = contentHandler
        self.bestAttemptContent = (request.content.mutableCopy() as? UNMutableNotificationContent)

        if let bestAttemptContent = bestAttemptContent {
            /* DEBUGGING: Uncomment the 2 lines below to check this extension is executing
                          Note, this extension only runs when mutable-content is set
                          Setting an attachment or action buttons automatically adds this */
            // print("Running NotificationServiceExtension")
            // bestAttemptContent.body = "[Modified] " + bestAttemptContent.body

            OneSignalExtension.didReceiveNotificationExtensionRequest(self.receivedRequest, with: bestAttemptContent, withContentHandler: self.contentHandler)
        }
    }

    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 {
            OneSignalExtension.serviceExtensionTimeWillExpireRequest(self.receivedRequest, with: self.bestAttemptContent)
            contentHandler(bestAttemptContent)
        }
    }
}

Testing the OneSignal SDK integration

​

Check mobile subscriptions

1

Launch your app on a test device.

The native push permission prompt should appear automatically if you added the requestPermission method during initialization.

2

Check your OneSignal dashboard

Before accepting the prompt, check the OneSignal dashboard:

• Go to Audience > Subscriptions.
• You should see a new entry with the status “Never Subscribed”.

3

Return to the app and tap Allow on the prompt.

4

Refresh the OneSignal dashboard Subscription's page.

The subscription’s status should now show Subscribed.

You have successfully created a mobile subscription. Mobile subscriptions are created when users first open your app on a device or if they uninstall and reinstall your app on the same device.

​

Set up test subscriptions

1

Add to Test Subscriptions.

In the dashboard, next to the subscription, click the Options (three dots) button and select Add to Test Subscriptions.

2

Name your subscription.

Name the subscription so you can easily identify your device later in the Test Subscriptions tab.

3

Create a test users segment.

Go to Audience > Segments > New Segment.

4

Name the segment.

Name the segment Test Users (the name is important because it will be used later).

5

Add the Test Users filter and click Create Segment.

You have successfully created a segment of test users. We can now test sending messages to this individual device and groups of test users.

​

Send test push via API

1

Get your App API Key and App ID.

In your OneSignal dashboard, go to Settings > Keys & IDs.

2

Update the provided code.

Replace YOUR_APP_API_KEY and YOUR_APP_ID in the code below with your actual keys. This code uses the Test Users segment we created earlier.

}'

3

Run the code.

Run the code in your terminal.

4

Check images and confirmed delivery.

If all setup steps were completed successfully, the test subscriptions should receive a notification with an image included:

Images will appear small in the collapsed notification view. Expand the notification to see the full image.

5

Check for confirmed delivery.

In your dashboard, go to Delivery > Sent Messages, then click the message to view stats.You should see the confirmed stat, meaning the device received the push.

You have successfully sent a notification via our API to a segment.

• No image received? Your Notification Service Extension might be missing.
• No confirmed delivery? Review the troubleshooting guide here.
• Having issues? Copy-paste the api request and a log from start to finish of app launch into a .txt file. Then share both with support@onesignal.com.

​

Send an in-app message

1

Close or background your app on the device.

This is because users must meet the in-app audience criteria before a new session starts. In OneSignal, a new session starts when the user opens your app after it has been in the background or closed for at least 30 seconds. For more details, see our guide on how in-app messages are displayed.

2

Create an in-app message.

• In your OneSignal dashboard, navigate to Messages > In-App > New In-App.
• Find and select the Welcome message.
• Set your Audience as the Test Users segment we used previously.

3

Customize the message content if desired.

4

Set Trigger to 'On app open'.

5

Schedule frequency.

Under Schedule > How often do you want to show this message? select Every time trigger conditions are satisfied.

6

Make message live.

Click Make Message Live so it is available to your Test Users each time they open the app.

7

Open the app and see the message.

After the in-app message is live, open your app. You should see it display:

Not seeing the message?

• Start a new session
  • You must close or background the app for at least 30 seconds before reopening. This ensures a new session is started.
  • For more, see how in-app messages are displayed.
• Still in the Test Users segment?
  • If you reinstalled or switched devices, re-add the device to Test Subscriptions and confirm it’s part of the Test Users segment.
• Having issues?
  • Follow Getting a Debug Log while reproducing the steps above. This will generate additional logging that you can share with support@onesignal.com and we will help investigate what’s going on.
