当我尝试以终止状态（当应用程序终止时）发送通知时，我的颤振 IOS 应用程序出现问题

Question

我正在开发一个具有推送通知属性的颤振应用程序，当应用程序处于前台或后台通知连续发出时一切正常，但是当应用程序处于终止状态时意味着当应用程序不在后台时，通知不会出现，为什么？

并且在 android 通知中在所有状态下都能正常工作（前台、后台、应用程序终止时的终止状态）

这是我在 IOS 中发送通知的有效负载

{"to":"Device-token","content_available":true,"data":{"title":"Message","body":"Lorem Ipsum 只是印刷和排版行业的虚拟文本。", "date":"Tue, 12 Jul 2022","time":"11:53","click_action":"FLUTTER_NOTIFICATION_CLICK","show_title":"测试通知标题。","id":123,"checkdate" :"2022-07-12","image":"https://crm.satoshifx.com/assets/images/satoshifx-notification.jpg"}}{"multicast_id":2817247928782996095,"success":1,"失败":0,"canonical_ids":0,"results":[{"message_id":"1657619612508875"}]}

您可以在发布模式下进行测试；

在你的主要

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  
  FirebaseMessaging.onBackgroundMessage(_firebaseMessagingBackgroundHandler);
  await flutterLocalNotificationsPlugin
      .resolvePlatformSpecificImplementation<
          AndroidFlutterLocalNotificationsPlugin>()
      ?.createNotificationChannel(channel);

  await FirebaseMessaging.instance.setForegroundNotificationPresentationOptions(
    alert: true,
    badge: true,
    sound: true,
  );
  runApp(const RestartWidget(child: const MyApp()));
}

///Define this outside your main 

Future<void> _firebaseMessagingBackgroundHandler(RemoteMessage message) async {
  await Firebase.initializeApp();
}
