我是颤振新手并尝试实现推送通知。我使用 ONE SIGNAL 进行推送通知

在这里，我初始化了一个信号并获取了playerId，并将其发送到服务器。

    void oneSignalInit() async {
    SharedPreferences preferences = await SharedPreferences.getInstance();
    OneSignal.shared.init('one signal id');
    OneSignal.shared.setInFocusDisplayType(OSNotificationDisplayType.notification);

    status = await OneSignal.shared.getPermissionSubscriptionState();

    var playerId = status.subscriptionStatus.userId;
    print(playerId);
    preferences.setString(Constants.PLAYER_ID, playerId);
}

在这里，我收到来自一个信号的通知并从中获取所需的数据。

 notificationHandler() {
OneSignal.shared.setNotificationReceivedHandler((OSNotification notification) {
  // will be called whenever a notification is received

  var data = notification.payload.additionalData;
  print(data['body']['tripID'].toString());
  showNotification(message);

});

现在，我正在提出我的自定义通知，使用 flutter_local_notification 依赖项

      showNotification(var msg) async {
    print("show notification is working");
    AndroidNotificationDetails androidPlatformChannelSpecifics =
    new AndroidNotificationDetails(
        msg, msg, msg);
    IOSNotificationDetails iOSPlatformChannelSpecifics =
    new IOSNotificationDetails();
    NotificationDetails platformChannelSpecifics = new …

在android中实现了dataBinding，但在编译时抛出错误

XML 代码

    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <View
