PS: The Warning logs are added by me for debugging in the respective functions in the plugin.

How to receive the payload in the app, after the notification is tapped from inactive/terminated state. This works fine in iOS as I get the payload in the subscribeToPushNotificationEvents listener. The same is not happening in Android.

From the logs, I can see that event is published before the activePlugin is set.

Hi @Neelansh-ns ,

Thanks for reaching out! Here are some things you can try to help resolve your issue:

• Ensure you are following all the steps in the Flutter SDK - Push Notifications docs.
  • For more in-depth documentation for the Android side, please refer to the Android SDK - Push Notifications docs.

If you continue to run into issues, please contact our Support Team by emailing support@braze.com. They will be able to help with your specific integration. In your email, please include:

• Code snippets/files containing your push notification integration on the Android and Dart side
• Verbose logs
• Screenshots or a recording of the current behavior

Thanks!

I'm able to solve this by adding a slight delay in the processPushNotificationEvent function, as there is a race condition happening here. The BrazePushReceiver sends out click event as soon as the notification is tapped.

2024-06-25 02:32:53.655 12273-12273 Braze v30....shReceiver io.invideo.ai                        I  Received broadcast message. Message: Intent { act=com.braze.action.BRAZE_PUSH_CLICKED cmp=io.invideo.ai/com.braze.push.BrazePushReceiver (has extras) }

And then the onAttachedToEngine is called which initializes the BrazeSDK.

By adding a few milliseconds delay in the processPushNotificationEvent, I get the correct notification payload on calling subscribeToPushNotificationEvents from the dart side.

Please refer to this customized Plugin file, where I have added logs. I have used the approach of adding a delay of 200ms to validate the bug.

Adding the delay fixes the bug. https://gist.github.com/Neelansh-ns/2e862e3f7522d78081c99d0ee36d7f37

I've opened a PR for the same here, where I'm storing the pending events while an activity gets attached. Please review: #78
