# Widget and In-App Messages

### Pop-up and In-App Message Presentation Behavior <a href="#pop-up-and-in-app-message-presentation-behavior" id="pop-up-and-in-app-message-presentation-behavior"></a>

All push notifications in Netmera work automatically—no additional coding is required. However, you can customize pop-up presentations and listen to push callbacks.

By default, when a popup notification or in-app message is received:

* If the app is in the foreground, the SDK displays pop-up notifications and in-app messages **immediately**.
* If the app is in the background, the SDK shows them **when the app returns to the foreground.**

### Receiving Popups and In-App Messages in the Background

To receive popups or in-app messages when the application is in the background, you need to enable **Remote Notifications** under **Background Modes** in **Capabilities**.

### Managing Pop-up Presentations <a href="#enable-disable-immediate-presentations" id="enable-disable-immediate-presentations"></a>

To enable or disable pop-up presentation, you need to call this methods

{% hint style="info" %}
To show pop-up on the app start or everywhere in the app, please call `Netmera.enablePopupPresentation();` to your `main.dart` file.
{% endhint %}

```dart
 Netmera.enablePopupPresentation();
```

```dart
 Netmera.disablePopupPresentation();
```

### Handle Widget URL's

**Step 1:** In order to use the widget URL callback, add these lines into `AppDelegate.swift` file.

<pre class="language-swift"><code class="lang-swift"><strong>import NetmeraNotification
</strong><strong>import netmera_flutter_sdk
</strong>
...
  override func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey : Any]? = nil) -> Bool {
    ...
<strong>    FNetmera.setPushDelegate(self)
</strong>    ..
  }
...

<strong>extension AppDelegate: NetmeraPushDelegate {
</strong><strong>    func urlOpeningDecision(for url: URL, push: NetmeraBasePush) -> PushDelegateDecision {
</strong><strong>        return .sdkHandles
</strong><strong>    }
</strong><strong>    
</strong><strong>    func openURL(_ url: URL, for push: NetmeraBasePush) {
</strong><strong>        FNetmera.openURL(url: url, forPushObject: push)
</strong><strong>    }
</strong><strong>}
</strong></code></pre>

{% hint style="info" %}
No need extra implementation for Android.
{% endhint %}

**Step 2:** Handle widget URL's in dart classes.

```dart
void _onWidgetUrlTriggered(String url) {
  // Handle widget URL
}

Netmera.onWidgetUrlTriggered(_onWidgetUrlTriggered);
```
