AAPT: error: resource android:attr/lStar not found.

I am Using flutter one signal package 3.5.4
everything was working Perfectly until i upgraded flutter to version 3.27.4

Now I Can no Longer build my app
using Flutter bulid apk or build appbundle results in an error message

FAILURE: Build failed with an exception.

• What went wrong:
  Execution failed for task ':onesignal_flutter:verifyReleaseResources'.

A failure occurred while executing com.android.build.gradle.tasks.VerifyLibraryResourcesTask$Action
Android resource linking failed
ERROR: G:\Nxt-Level\Mobile Apps\hatrick\build\onesignal_flutter\intermediates\merged_res\release\values\values.xml:2657: AAPT: error: resource android:attr/lStar not found.

• Upgrading to version 5.2.9 Solves the Problem but
  it creates another one ( Which is the main reason why i was using the 3.5.4 version) and the problem is
  if i received a notification while the app is not open (completely closed) upon clicking i expect the app to wake and open
  but it doesn't and i need to click on the notification once again

`dart
initOneSignal() {
OneSignal.Debug.setLogLevel(
OSLogLevel.error,
);

OneSignal.initialize (AppConstants.oneSignalAppID);
OneSignal.Notifications.requestPermission(true);
}

setupNotification(BuildContext context) {
OneSignal.Notifications.addClickListener((openedResult) {
PodcastEntity podcastEntity = PodcastModel.fromJson(
jsonDecode(
openedResult.notification.additionalData!["podcast"],
),
).toEntity;
context.read().add(
NotificationClickedEvent(
entity: podcastEntity,
),
);
});
}
`

Hi @tazy-dev, the android:attr/lStar issue looks related to some compileSdk versions. I recommend using v5.x.x of this SDK.

Upgrading to version 5.2.9 Solves the Problem but
it creates another one ( Which is the main reason why i was using the 3.5.4 version) and the problem is
if i received a notification while the app is not open (completely closed) upon clicking i expect the app to wake and open
but it doesn't and i need to click on the notification once again

Are you seeing this on Android, iOS, or both?

For now Iam only developing it for android
So yeah only android...
Strangely as I said before when I was working with v 3.5.4 didn't have this problem...
But now it's happening and I don't know why
Clicking on a notification when app is off won't wake the application and open the notification
And clicking on the notification again is needed
