Уведомление о показе дважды на Flutter ⇐ Android

[Anonymous]

Я застрял. Мое уведомление в фоновом шоу дважды. Но на переднем плане только одно уведомление. Это мой код < /p>
Future _firebaseMessagingBackgroundHandler(RemoteMessage message) async {
// If you're going to use other Firebase services in the background, such as Firestore,
// make sure you call `initializeApp` before using other Firebase services.
await Firebase.initializeApp();
if(
!AwesomeStringUtils.isNullOrEmpty(message.notification?.title, considerWhiteSpaceAsEmpty: true) ||
!AwesomeStringUtils.isNullOrEmpty(message.notification?.body, considerWhiteSpaceAsEmpty: true)
){
// print('message also contained a notification: ${message.notification.body}');

String imageUrl;
imageUrl ??= message.notification.android?.imageUrl;
imageUrl ??= message.notification.apple?.imageUrl;
print(imageUrl);
if(imageUrl == null){
var id = Random().nextInt(2147483647);
await AwesomeNotifications().createNotification(
content: NotificationContent(
id: id,
title: message.notification.title,
body: message.notification.body,
color: Colors.orange,
customSound: 'resource://raw/alert',
notificationLayout: NotificationLayout.BigText,
channelKey: 'basic_channel_background',
payload: {'data':message.data['payload']}
),
actionButtons: [
NotificationActionButton(
label: 'Lihat Selengkapnya',
enabled: true,
buttonType: ActionButtonType.Default,
key: 'background',
)
]
);
}else{
await AwesomeNotifications().createNotification(
content: NotificationContent(
id: Random().nextInt(2147483647),
title: message.notification.title,
body: message.notification.body,
bigPicture: imageUrl,

// End Background Message

А это мой код переднего плана < /p>
// Foreground Apps
Future main() async{
WidgetsFlutterBinding.ensureInitialized();

await AwesomeNotifications().initialize(
'resource://mipmap/launcher_icon',

AwesomeNotifications().actionStream.listen((event) async{
print('event received!');
var data = event.toMap();
if(data['buttonKeyPressed'] == "background"){
SharedPreferences prefs = await SharedPreferences.getInstance();
prefs.setString("Navigate", data['payload']['data']);
}else{
_navigateToItemForeground(data['payload']['data']);
}
// do something based on event...
// AwesomeNotifications().actionSink.close();
});
}

FirebaseMessaging.onMessage.listen((RemoteMessage message) async{
RemoteNotification notification = message.notification;
AndroidNotification android = message.notification?.android;
if (notification != null && android != null && !kIsWeb) {
if(!AwesomeStringUtils.isNullOrEmpty(message.notification?.title, considerWhiteSpaceAsEmpty: true) ||
!AwesomeStringUtils.isNullOrEmpty(message.notification?.body, considerWhiteSpaceAsEmpty: true)){
print("something");

String imageUrl;
imageUrl ??= notification.android?.imageUrl;
imageUrl ??= notification.apple?.imageUrl;

if(imageUrl == null){
await AwesomeNotifications().createNotification(

И это мой скриншот

Я попытался изменить удивительное уведомление, но результат такой же. Не могли бы вы помочь мне решить это? Надеюсь, вы можете мне помочь. Большое спасибо
