Minimal reproduce code
Basically, I have an AppController which is the very parent controller and overrides the onInit and initializes PostScreenController using Get.put

Hello!
Please, it is better if you provide a minimal reproduce code, only explain the code usually leads to not being able to reproduce your issue locally

Will do in a bit... thanks

Here's a minimal reproducible code

import 'package:flutter/material.dart';
import 'package:get/get.dart';

void main() {
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    Get.put(AppController());
    return GetMaterialApp(home: HomeScreen());
  }
}

class HomeScreen extends StatelessWidget {
  const HomeScreen({Key key}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(title: Text('Test')),
      body: Text('Test'),
    );
  }
}

class AppController extends GetxController {
  static AppController get to => Get.find();

  @override
  void onInit() async {
    Get.put(PostScreenController());
    super.onInit();
  }
}

class PostScreenController extends GetxController {
  final friendsController =
      Get.put(FriendsController(pickerMode: true), tag: 'sheet');
}

class FriendsController extends GetxController {
  final bool pickerMode;
  FriendsController({this.pickerMode = false});
}

It looks like it has something to do with the tag set to the FriendsController. Removing the tag fixes the error

[jonataslaw]

This has already been fixed by d208a61

I will update pub.dev soon.

[jonataslaw]

fix on 3.4.4

Great to hear! Thanks a lot
