Research direction

Start by checking the firebase_messaging iOS implementation around FLTFirebaseMessagingPlugin.configureNotificationCenterDelegate() and how foreground messages reach FirebaseMessaging.onMessage. Reproduce the report on an iOS simulator using the provided notification and data payload, then compare behavior with the banner presentation options. Done means identifying why the foreground callback receives no data and confirming the expected behavior with a focused regression test.
