如何在 flutter 后台收到本地通知时调用 function

Question

I want to build one functionality in my flutter app. I am using the awesome_notification package to show scheduled notifications.

Is there any way that I can trigger an API call when a notification is received in the background? (when the app was killed or terminated). I want to do it on the flutter side but You can also suggest how to do it in native android and IOS if it is possible. Native integration would also be accepted.

Please share a demo or example.

Thanks!

iOS Note: In iOS, you can determine whether an application is launched as a result of the user tapping the action button or whether the notification was delivered to the already-running application by examining the application state. In the delegate's implementation of the application:didReceiveRemoteNotification: or application:didReceiveLocalNotification: method, get the value of the applicationState property and evaluate it. If the value is UIApplicationStateInactive, the user tapped the action button; if the value is UIApplicationStateActive, the application was frontmost when it received the notification.
