🐛 [Firebase_messaging 8.0.0-dev.8] 'onLaunch' not showing the notification

[evripidesk]

Hello

I migrated to the new firebase messaging 8.0.0 dev8 i tried it and is working but I have issue when notification received and the application is killed and user click on notification not showing the message , in the case that the app is in the backround is working fine the issue is only 'onLaunch'

fcm.FirebaseMessaging.onMessageOpenedApp.listen((message) {
      print('Got a message whilst in the foreground!');
      print('Message data: ${message.data}');
      print(message.data['extraPayLoad1']);

});

Hi @evripidesk Could you explain a bit more what is the expected vs actual behavior here? Using the official example on the latest flutter master 1.24.0-8.0.pre.208 and firebase_messaging: ^8.0.0-dev.8 the onMessageOpenedApp callback works just fine if the app is in background or killed.

flutter doctor -v

Based on your print statements maybe you meant the onMessage callback? Could you also please provide your flutter doctor -v and flutter pub deps -- --style=compact? Is this on android or iOS?

Thank you

I have the below code

  void initState() {
...
fcm.FirebaseMessaging.onMessageOpenedApp.listen((message) {
      print('Got a message whilst in the foreground!');
      print('Message data: ${message.data}');
      print(message.data['extraPayLoad1']);
          _showItemDialog2(message.data);
});
fcm.FirebaseMessaging.onMessage.listen((fcm.RemoteMessage message) {
      print('Got a message whilst in the foreground!');
      print('Message data: ${message.data}');
          _showItemDialog2(message.data);

});

}

When I am on foreground the _showItemDialog2(message.data) called successful when I am on background the notification come to notification tray I click on notification and the _showItemDialog2(message.data) called successful but when the app is killed the notification come to notification tray I click on notification the app open but the _showItemDialog2(message.data) is not call

I tried it on android and iOS (real devices)

@evripidesk If you look at the implementation of onMessageOpenedApp you will see the following:

/// A Stream event will be sent if the app has opened from a background state
/// (not terminated).
///
/// If your app is opened via a notification whilst the app is terminated,
/// see [getInitialMessage].
static Stream<RemoteMessage> get onMessageOpenedApp {
...

[paynekw]

@evripidesk please share the iOS version running on your iPhone.

[evripidesk]

@paynekw I will try the

    messaging.getInitialMessage().then((message) {

iOS version 14.2

[evripidesk]

thank you this is working fine

messaging.getInitialMessage().then((message) {

tested on iOS 14.2 and android

[markusaksli-nc]

Closing this based on your last message, glad you solved it and thanks for the helpful comment @paynekw
