Flutter: iOS notification background handler

How to handle iOS background notification click_action when it is null ?

{
 "to" : "abcd1234",
 "collapse_key" : "type_a",
 "notification" : {
     "title": "Testing",
     "body" : "Testing 1 2 3 4 5 6 7"
 },
 "data" : {
     "click_action": "FLUTTER_NOTIFICATION_CLICK",
     "route": "/Home",
 }
}

onBackgroundMessage: Platform.isAndroid ? BackgroundHandler.backgroundHandler : null

This post mentioned onBackgroundMessage not implemented in iOS just use for android. Is there a way to handle in iOS ? Thanks.

Yes.

If you did all the ios firebase configurations using XCode, you can use the native swift functions to listen to the background notifications on iOS.

Inside your AppDelegate class,

 override func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any]) {
    
    }
    
    override func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any],
                              fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void) {
        
        /// Here you will get the silent background notification .
        /// May be you can call you flutter code from here if you need.
        /// Make sure that you end your processing quickly, else you will not get the background notification regularly and timely from iOS.


        /// After you completed, make sure you call the completionHandler so that iOS knows you are done with your background task and you completed it so quickly.

        completionHandler(UIBackgroundFetchResult.newData)
        
    }

FlutterFire team is working on this to bring to the flutter side and you can expect this very soon I think by looking at their GitHub PRs.
