Additional context and comments

Iam sending notifications using Firebase Admin SDK for PHP and receiving in Flutter app using firebase and flutter_local_notification package.

My flutter app receiving notifications well in Android devices in foreground, background and terminated. iOS devices receiving notifications only in foreground. Notifications presents by flutter_local_notification package.

The problem that app not receiving notifications in ios device when the app in background and terminated.

Problem: To get notifications in ios device when the app in background and terminated I need to set 'alert' => $data, then the app receiving notifications, BUT notifications sends directly to the device not to the app via flutter_local_notification.

I want to present notifications in all modes and devices via flutter_local_notification.

Is there any thing which disable notifications receiving in ios device when the app in background and terminate? How to solve it?
