iOS

Description

FirebaseMessaging.onMessage.listen is not triggered on iOS when a new push notification is received while the app is running in foreground. When the app is running in background, iOS displays the push notification as expected. On Android, everything works without any problems.

Doctor summary (to see all details, run flutter doctor -v):
[✓] Flutter (Channel stable, 3.41.2, on macOS 26.2 25C56 darwin-arm64, locale de-DE)
[✓] Android toolchain - develop for Android devices (Android SDK version 36.1.0)
[✓] Xcode - develop for iOS and macOS (Xcode 26.2)

Versions: firebase_core: ^4.9.0, firebase_messaging: ^16.2.2, Flutter project was created with version 3.41.2

Does anyone have an idea what the problem is? Thanks in advance! :)

i have the same issue.

I had modified ios/Runner/SceneDelegate.swift for method channels. I reset the code in this file to Flutters default code:

import Flutter
import UIKit
class SceneDelegate: FlutterSceneDelegate {}

Now, FirebaseMessaging.onMessage.listen works as expected.
