4 years ago Hi @rgodlontonshaw,
It appears your project has been updated to version 1.1.2 of the pushy_flutter Dart package. This new version invokes your notification listener in the background, even if your app is not running, allowing you to generate a notification from Dart code. It requires a slight code change.
To update your project to the new Pushy Flutter SDK:
1) Please ensure your Flutter Android project has been updated to Flutter 1.12+ for compatibility with the new version of our plugin. Your android/app/src/main/AndroidManifest.xml should contain a <meta-data> attribute labeled flutterEmbedding with a value of 2.
2) Remove the following lines from your android/app/src/main/AndroidManifest.xml:
<!-- Pushy Notification Receiver -->
<!-- Incoming push notifications will invoke the following BroadcastReceiver -->
<receiver android:name="me.pushy.sdk.flutter.PushReceiver" android:exported="false">
<intent-filter>
<!-- Do not modify this -->
<action android:name="pushy.me" />
</intent-filter>
</receiver>3) Remove any existing Pushy.setNotificationListener((data) => {}) method from your application.
4) Add the following method to your main.dart file, right after the import statements, and outside any Widget class declaration, to process push notifications in the background via a Flutter background isolate:
// Please place this code in main.dart,
// After the import statements, and outside any Widget class (top-level)
void backgroundNotificationListener(Map<String, dynamic> data) {
// Print notification payload data
print('Received notification: $data');
// Notification title
String notificationTitle = 'MyApp';
// Attempt to extract the "message" property from the payload: {"message":"Hello World!"}
String notificationText = data['message'] ?? 'Hello World!';
// Android: Displays a system notification
// iOS: Displays an alert dialog
Pushy.notify(notificationTitle, notificationText, data);
// Clear iOS app badge number
Pushy.clearBadge();
}Feel free to modify this sample code to suit your own needs.
5) Call the Pushy.setNotificationListener(backgroundNotificationListener) method after Pushy.listen() to configure the background notification listener:
// Listen for push notifications received
Pushy.setNotificationListener(backgroundNotificationListener);Please let us know if it resolves the issue.

Hi there,
Please could you assist me. I have upgraded my Flutter SDK and Pushy library (pushy_flutter: ^1.1.2) recently and now I no longer receive any push notifications. I am using the flutter pushy demo code exactly.
I see this error in my logs. I/flutter (18015): Pushy: Error retrieving handle for Flutter callbacks
I have tried everything I possibly can think of. The notifications were working before on iOS and Android. Any advice/guidance/assistance would be much appreciated.
