Flutter android do not get notification when app is killed

Question

I am using firebase console to send the notification to my android device, it's working fine when the app is in background or foreground state. But it's not receiving the notification in killed state since m not attaching any data it should not be a data notification.

_firebaseMessaging.configure(
  onMessage: (Map<String, dynamic> message) async {
    MessageDialog messageDialog = new MessageDialog();
    messageDialog.information(context, "Notification");
    print('on message $message');
  },
  onResume: (Map<String, dynamic> message) async {
    print('on resume $message');
  },
  onLaunch: (Map<String, dynamic> message) async {
    print('on launch $message');
  },
);

Solution

For receiving notification when an app is in background you can use onBackgroundMessage

firebaseMessaging.configure(
  onMessage: (Map<String, dynamic> message) {
    print('on message $message');
    handleNotification(message);
    return;
  },
  onBackgroundMessage: fcmBackgroundMessageHandler,
  onResume: (Map<String, dynamic> message) {
    print('$fcmTag on resume $message');
    return;
  },
  onLaunch: (Map<String, dynamic> message) {
    print('$fcmTag on launch $message');
    return;
  },
);

Here is the fcmBackgroundMessageHandler

static Future<dynamic> fcmBackgroundMessageHandler(Map<String, dynamic> message) {

if (message.containsKey('data')) {
  // Handle data message
  final dynamic data = message['data'];
  //handleNotification(message);
}

if (message.containsKey('notification')) {
  // Handle notification message
  final dynamic notification = message['notification'];
} }

Note: I am still finding a solution to receive a solution when the app is in Kill state. I will update answer once get the solution
