  // log(message.data.toString(),);

  // log(message..toString(),);
  if (notification.data['model'] == 'order') {
    if (prefs.getString('user_type') == 'customer') {

when app is terminated there is no event is fired instead you can get the notification opened the app await FCMConfig.instance.getInitialMessage();

Thanks for your reply I try it but still same

[mo-ah-dawood]

i think you has to try it in release mode as you can not debug the terminated app try to get the message in your main function after init fcm

void main() async{
  await   await FCMConfig.instance.init();
 /// there is no need for the next line,package call it for you
 /// await Firebase.initializeApp();
 var notification=await FCMConfig.instance.getInitialMessage();
 /// you may get here the screen you want to open and path it to MyApp as at this point no navigation
  runApp(
    Phoenix(
      child: MyApp(
         screen: /// your first screen
       ),
    ),
  );
}
