Flutter Firebase 無法理解堆棧跟蹤

Question

我無法理解這個堆棧跟蹤以及它出現的原因。 據我了解，這與 firebase 消息傳遞有關。

E/AndroidRuntime(26033): java.lang.AssertionError

I/Process (26033): Sending signal. PID: 26033 SIG: 9
Lost connection to device.

但根據文檔，我處理 firebase 和通知權限的預配置是正確的。

這是我的主要的樣子，

void main() async {
  WidgetsFlutterBinding.ensureInitialized();

  await Firebase.initializeApp(
    options: DefaultFirebaseOptions.currentPlatform,
  );

  FirebaseMessaging messaging = FirebaseMessaging.instance;

  NotificationSettings settings = await messaging.requestPermission(
    alert: true,
    announcement: false,
    badge: true,
    carPlay: false,
    criticalAlert: false,
    provisional: false,
    sound: true,
  );

  print('User granted permission: ${settings.authorizationStatus}');


  FirebaseMessaging.onBackgroundMessage(_firebaseMessagingBackgroundHandler);

  await FirebaseMessaging.instance.setForegroundNotificationPresentationOptions(
      alert: true, badge: true, sound: true);

  DatabaseBinding().dependencies();

  runApp(MyApp());
}

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

下面我在我的策略屏幕中處理權限，

Map<Permission, PermissionStatus> statuses = await [
      Permission.storage,
      Permission.notification,
      Permission.camera
    ].request();

    if (!statuses.containsValue(PermissionStatus.denied)) {
      showGeneralDialog(
          context: context,
          useRootNavigator: false,......so_on

請讓我知道，堆棧跟蹤到底說了什么，如果我遺漏了什么，請解釋一下。

問題似乎來自更新 13.0.0 - 內置通知權限處理 function
