Controller Life cycle

my_controller.dart

import 'package:flutter_getx/student.dart';
import 'package:get/get.dart';

import 'home.dart';

class MyController extends GetxController {
  var count = 0;

  void increment() async {
    await Future<int>.delayed(
      Duration(seconds: 5));
    this.count++;
    update();
  }

  void cleanUpTask()
  {
    print("Clean up task");
  }


 //Better Approach
  @override
  void onInit() {
   print("Init Called");
    super.onInit();
  }

  @override
  void onReady() async {
    super.onReady();


  }
  @override
  void onClose() {

    super.onClose();
  }

}

I'm new to GetX.

I have recreated the this scenario and found my increment() method not working.
I have include the method under onInit() methods.

@OverRide
void onInit() {
increment(); // Added here
print("Init Called");
super.onInit();
}

My screen doesn't show number count increment.
Please advice on this?
