onesignal que acaba de ser creada.


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.

3. Configuración de iOS
Es probable que el proyecto descargado no esté listo para lanzar en iOS. Antes de configurar las adiciones específicas de OneSignal, necesitarás asegurarte de que el proyecto esté completamente construido. Para hacerlo:- Abre una ventana de Terminal, cd (cambiar directorio) a la carpeta
iosde tu proyecto descargado. - En Terminal escribe
flutter build iosy 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 instally presiona enter. Espera a que la instalación del pod se complete.
.xcworkspace en Xcode ubicado en la carpeta ios de tu proyecto.
Selecciona el proyecto raíz > tu objetivo de aplicación principal > Signing & Capabilities.
Si no ves Push Notifications habilitado, haz clic en + Capability y agrega Push Notifications. Asegúrate de ingresar los detalles correctos para tu Team y Bundle Identifier.


Agregar Notification Service Extension
La OneSignalNotificationServiceExtension permite que tu aplicación iOS reciba notificaciones enriquecidas con imágenes, botones e insignias. También es requerida para las funciones de analíticas de Confirmed Delivery de OneSignal. En Xcode selecciona File > New > Target… Selecciona Notification Service Extension y luego Next.
OneSignalNotificationServiceExtension y presiona Finish.



Agregar App Groups
Los App Groups permiten que tu aplicación y la OneSignalNotificationServiceExtension se comuniquen cuando se recibe una notificación, incluso si tu aplicación no está activa. Esto es requerido para insignias y Confirmed Deliveries. Selecciona tu Main App Target > Signing & Capabilities > + Capability > App Groups.
group.YOUR_BUNDLE_IDENTIFIER.onesignal donde YOUR_BUNDLE_IDENTIFIER es el mismo que el “Bundle Identifier” de tu aplicación principal.


group.YOUR_BUNDLE_IDENTIFIER.onesignal donde YOUR_BUNDLE_IDENTIFIER es el mismo que el “Bundle Identifier” de tu aplicación principal.
NO INCLUYAS OneSignalNotificationServiceExtension.

Instrucciones opcionales para configurar nombre de App Group personalizado
Este paso solo es requerido si no quieres usar el nombre de app group predeterminado (que es
group.{your_bundle_id}.onesignal).Abre tu archivo Info.plist y agrega una nueva OneSignal_app_groups_key como tipo String.Ingresa el nombre del grupo que verificaste en el último paso como su valor.Asegúrate de hacer lo mismo para el Info.plist bajo la carpeta OneSignalNotificationServiceExtension.Agregar SDK de OneSignal a la OneSignalNotificationServiceExtension
Actualiza tuios/Podfile para incluir:
Podfile asegúrate de tener platform :ios, '11.0'. - O una versión más nueva de iOS si tu aplicación lo requiere.
cd al directorio ios, y ejecuta pod install.
Si ves el error a continuación, agrega use_frameworks! en la parte superior de tu podfile e intenta nuevamente.
Código de OneSignalNotificationServiceExtension
En el navegador de proyectos de Xcode, selecciona la carpeta OneSignalNotificationServiceExtension y abre el archivoNotificationService.m o NotificationService.swift.
Reemplaza todo el contenido del archivo con el siguiente código.

Testing the OneSignal SDK integration
This guide helps you verify that your OneSignal SDK integration is working correctly by testing push notifications, subscription registration, and in-app messaging.Check mobile subscriptions
Launch your app on a test device.
The native push permission prompt should appear automatically if you added the 
requestPermission method during initialization.
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”.

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
Test subscriptions are helpful for testing a push notification before sending a message.Add to Test Subscriptions.
In the dashboard, next to the subscription, click the Options (three dots) button and select Add to Test Subscriptions.

Name your subscription.
Name the subscription so you can easily identify your device later in the Test Subscriptions tab.
Name the segment.
Name the segment
Test Users (the name is important because it will be used later).Send test push via API
Get your App API Key and App ID.
In your OneSignal dashboard, go to Settings > Keys & IDs.
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.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.
Send an in-app message
In-app messages let you communicate with users while they are using your app.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.
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.

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

Make message live.
Click Make Message Live so it is available to your Test Users each time they open the app.
You have successfully setup the OneSignal SDK and learned important concepts like:
- Gathering Subscriptions, setting Test subscriptions, and creating Segments.
- Sending Push with images and Confirmed Delivery using Segments and our Create message API.
- Sending In-app messages.
User identification
Previously, we demonstrated how to create mobile Subscriptions. Now we’ll expand to identifying Users across all their subscriptions (including push, email, and SMS) using the OneSignal SDK. We’ll cover External IDs, tags, multi-channel subscriptions, privacy, and event tracking to help you unify and engage users across platforms.Assign External ID
Use an External ID to identify users consistently across devices, email addresses, and phone numbers using your backend’s user identifier. This ensures your messaging stays unified across channels and 3rd party systems (especially important for Integrations). Set the External ID with our SDK’slogin method each time they are identified by your app.
OneSignal generates unique read-only IDs for subscriptions (Subscription ID) and users (OneSignal ID).As users download your app on different devices, subscribe to your website, and/or provide you email addresses and phone numbers outside of your app, new subscriptions will be created.Setting the External ID via our SDK is highly recommended to identify users across all their subscriptions, regardless of how they are created.
Add Tags
Tags are key-value pairs of string data you can use to store user properties (likeusername, role, or preferences) and events (like purchase_date, game_level, or user interactions). Tags power advanced Message Personalization and Segmentation allowing for more advanced use cases.
Set tags with our SDK addTag and addTags methods as events occur in your app.
In this example, the user reached level 6 identifiable by the tag called current_level set to a value of 6.




Add email and/or SMS subscriptions
Earlier we saw how our SDK creates mobile subscriptions to send push and in-app messages. You can also reach users through emails and SMS channels by creating the corresponding subscriptions.- Use the
addEmailmethod to create email subscriptions. - Use the
addSmsmethod to create SMS subscriptions.

Best practices for multi-channel communication
- Obtain explicit consent before adding email or SMS subscriptions.
- Explain the benefits of each communication channel to users.
- Provide channel preferences so users can select which channels they prefer.
Privacy & user consent
To control when OneSignal collects user data, use the SDK’s consent gating methods:setConsentRequired(true): Prevents data collection until consent is given.setConsentGiven(true): Enables data collection once consent is granted.
Prompt for push permissions
Instead of callingrequestPermission() immediately on app open, take a more strategic approach. Use an in-app message to explain the value of push notifications before requesting permission.
For best practices and implementation details, see our Prompt for push permissions guide.
Listen to push, user, and in-app events
Use SDK listeners to react to user actions and state changes. The SDK provides several event listeners for you to hook into. See our SDK reference guide for more details.Push notification events
addClickListener(): Detect when a notification is tapped. Helpful for Deep Linking.addForegroundLifecycleListener(): Control how notifications behave in foreground.
User state changes
addObserver()for user state: Detect when the External ID is set.addPermissionObserver(): Track the user’s specific interaction with the native push permission prompt.addObserver()for push subscription: Track when the push subscription status changes.
In-app message events
addClickListener(): Handle in-app click actions. Ideal for deep linking or tracking events.addLifecycleListener(): Track full lifecycle of in-app messages (shown, clicked, dismissed, etc.).
