[firebase_messaging] On resume and on launch not trigger for IOS

[curlyeto]

Hi everyone.

Works in all situations on android but On launch and on resume do not trigger when app is in background or terminated.

Flutter doctor version

ertugrul@ertugruls-Mac ~ % flutter doctor -v

App Delegate.swift

import UIKit
import Flutter
import FirebaseMessaging

@UIApplicationMain
@objc class AppDelegate: FlutterAppDelegate {
override func application(
_ application: UIApplication,
didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
) -> Bool {
GeneratedPluginRegistrant.register(with: self)
if #available(iOS 10.0, *) {
UNUserNotificationCenter.current().delegate = self as? UNUserNotificationCenterDelegate
}
return super.application(application, didFinishLaunchingWithOptions: launchOptions)
}
override func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
let deviceTokenString = deviceToken.reduce("", {$0 + String(format: "%02X", $1)})
print("==== didRegisterForRemoteNotificationsWithDeviceToken ====")
print(deviceTokenString)
Messaging.messaging().apnsToken = deviceToken
}
}

Fcm code

_fcm.configure(onMessage: (Map<String, dynamic> message) async {
print("onMessage tetkilendi: $message");
showNotification(message);
},
onBackgroundMessage: Platform.isIOS?null:myBackgroundMessageHandler,
onLaunch: (Map<String, dynamic> message) async {
print("onLaunch tetiklendi: $message");
showNotification(message);
},
onResume: (Map<String, dynamic> message) async {
print("onResume tetiklendi: $message");
showNotification(message);
},
);

Info.plist

<key>FirebaseAppDelegateProxyEnabled</key> <string>NO</string>

Firebase messagin version is 6.0.16. The code in the above on launch and on resume doesn't work print line when the above code is in the background or closed. Is there an error in the code I wrote or is it in the fcm package?
