Flutter Firebase 无法理解堆栈跟踪

Question

我无法理解这个堆栈跟踪及其出现的原因。据我所知，这与 firebase 消息传递有关。

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

但根据文档，我处理 firebase 和通知权限的预配置是正确的。

这就是我的主要样子，

下面我正在策略屏幕中处理权限，

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);
}

请让我知道堆栈跟踪到底说了什么，如果我遗漏了什么，请解释一下。
