Hello, I have been looking into advanced notification handling as well. It seems much of it can be accomplished using custom actions and the https://pub.dev/packages/firebase_messaging package which automatically gets added when you turn on Push Notification in the FlutterFlow configuration.

To get the device push token you can create a custom action with the following code as an example:

// Automatic FlutterFlow imports\nimport '/backend/backend.dart';\nimport '/backend/schema/structs/index.dart';\nimport '/flutter_flow/flutter_flow_theme.dart';\nimport '/flutter_flow/flutter_flow_util.dart';\nimport '/custom_code/actions/index.dart'; // Imports other custom actions\nimport '/flutter_flow/custom_functions.dart'; // Imports custom functions\nimport 'package:flutter/material.dart';\n// Begin custom action code\n// DO NOT REMOVE OR MODIFY THE CODE ABOVE!\n\nimport 'package:firebase_messaging/firebase_messaging.dart';\n\nFuture<void> getDevicePushToken() async {\n  // Add your function code here!\n  try {\n    String? token = await FirebaseMessaging.instance.getToken();\n    print('device push token: $token');\n    FFAppState().DeviceToken = token as String;\n    print('device push token updated to DeviceToken state variable');\n  } catch (e) {\n    print('device push token error: $e');\n  }\n}

I am currently now looking at how to handle and intercept background push notifications and change the message on the fly before presenting to the user. Anyone who has more information on advanced notification handling please post any tips you may have!
