GetX: lifecycle methods are not called for nested controllers-CodePudding

I have a configuration of nested GetX controllers, which represent my data model. They look like this (I shortened the code to show only controllers structure):

class AppController extends GetxController {
  final package = PackageController().obs; 
  
  void openPackage() {
  // some code with unzipping, parsing and eventually creating instance of PackageController

  package.value = packageController;
  }
}

class PackageController extends GetxController {
   final rounds = RxList<RoundController>();

 void addRound() {
    rounds.add(RoundController());
  }

  void deleteRound(int index) {
    rounds.removeAt(index);
  }
}

class RoundController extends GetxController {
  final themes = RxList<ThemeController>();

  void addTheme() {
    themes.add(ThemeController());
  }

  void deleteTheme(int index) {
    themes.removeAt(index);
  }
}

It goes deeper, but that's enough for understanding. In my UI widgets I access AppController with final store = Get.put(AppController()); and through it I have access to any nested controller I need.

Now to the problem: lifecycle methods like onInit() are called only for AppController() and not for any of the nested ones. So, is there some trick I need to know, or I use GetX in a wrong way, or what?

CodePudding user response：

The lifecycle methods are called only if the GetX dependency injection system creates the instances. Therefore you need to create these instances with Get.put() or Get.lazyPut() like this:

    rounds.add(Get.lazyPut(()=>RoundController()));
    themes.add(Get.lazyPut(()=> ThemeController()));
