iOS didNotificationLaunchAppreturn false and nullable payload when click on Notification in killed State

[VictorJava]

Describe the bug didNotificationLaunchApp returns false, and the payload is empty if the app was in a terminated state and the user clicked on the DarwinNotificationAction. Keep in mind that Android works as expected for similar steps. I encountered with issue only on iOS..

To Reproduce

1. I receive Pushes using the library https://pub.dev/packages/firebase_messaging
2. I added buttons to a category during app initialization. For example, the active_leak category has two buttons. Please take a look code below.
3. Open the app at least once.
4. Allow notifications for the app.
5. Minimize the app and swipe it away (Terminate state – the app is not running in the background or in the list of active apps).
6. Send a push notification via APNs, where the category matches the one from step 1: "category": "active_leak".
7. Receive the push notification.
8. Tap on one of the buttons.
9. The app opens.
10. getInitialMessage(https://pub.dev/packages/firebase_messaging) returns null and even final NotificationAppLaunchDetails? notificationAppLaunchDetails = await notificationsPlugin.getNotificationAppLaunchDetails().didNotificationLaunchApp returns false

Expected behavior didNotificationLaunchApp should return true, and the payload should not be empty if the app was opened using DarwinNotificationAction. Isn't that correct?

That is how I add the ActionButtons using the flutter_local_notifications library

DarwinNotificationAction actionIgnoreLeak = DarwinNotificationAction.plain(
      NotificationButtonAction.ignoreLeak.value,
      ignoreStr,
      options: <DarwinNotificationActionOption>{
        DarwinNotificationActionOption.foreground,
      },
    );

    DarwinNotificationAction actionActiveLeak = DarwinNotificationAction.plain(
      NotificationButtonAction.activeLeak.value,
      detailsStr,
      options: <DarwinNotificationActionOption>{
        DarwinNotificationActionOption.foreground,
      },
    );

    DarwinNotificationCategory categoryIgnoreAndDetails =
        DarwinNotificationCategory(
            NotificationBuilder.darwinNotificationCategoryActiveLeak,
            actions: <DarwinNotificationAction>[
          actionIgnoreLeak,
          actionActiveLeak,
        ]);

    initializationSettingsDarwin = DarwinInitializationSettings(
      requestAlertPermission: false,
      requestBadgePermission: false,
      requestSoundPermission: false,
      notificationCategories: <DarwinNotificationCategory>[
        categoryIgnoreAndDetails
      ],
    );

I am using the Postman to sent Pushes on my device. That is my JSON for Postman call. Feel free to check https://stackoverflow.com/a/62670409/21734721 how to grab Bearer token from Google for Postman. Sample code to send push via the Postman

{
  "message": {
    "token": "eztm3jfE9UsgrphZUCSSMe:APA91bFj8qulosQh-_4mGlBk-96eWRQ62_kesdSQ0ICGVSKM9ylKVZWBtzhbN5esGMS5cJK3d4epzUDnq_q1CC8HKp3vCUi-faJLIlE7S_5eK4u8HxlDcCs",
    "notification": {
      "title": "some text",
      "body": "some text (optional)",
  },
    "data": {
      "style": "red_high_leak",
      "title": "some text (optional)",
      "message": "some text",
      "bodyAction": "active_leak",
      "contextDataType": "leak",
    },
    "apns": {
       "headers": {
         "apns-priority": "5",
       },
       "payload": {
         "aps": {
           "category": "active_leak",
           "content-available": 1,
           "mutable-content" : 1,
         }
       }
     },
  },
}

Based on what you've mentioned, the notification being shown is a push notification via FCM. Is this correct? If so, then the issue would be on FCM side. The getNotificationAppLaunchDetails() method is only intended for local notifications

@MaikuB Thank you for your reply. I have already created a ticket in FCM repo to research it https://github.com/firebase/flutterfire/issues/17051

You can get notification details in terminated state using firebase messaging getInitialMessage() method
