Does making a Provider from riverpod autoDispose, dispose variables within the provider including controllers?

Question

I have a scroll controller in my provider. I want to know if I make the provider 'autoDispose', When the provider eventually gets auto disposed, does this dispose the controller within the provider to ? Or do I still need to dispose the scrollController.

Sample code:

import 'package:flutter_riverpod/flutter_riverpod.dart';

final myProvider = Provider.autoDispose(
  (ref) {
    return MyNotifier();
  },
);

class MyNotifier{
  final scrollController = ScrollController(initialScrollOffset: 5.0);
}

You should not be placing anything to do with the view layer into Riverpod providers. Riverpod is for the data layer and the control layer, not the view layer, and a ScrollController or TextEditingController should never be in a Riverpod provider. Those controllers belong in single-widget state, either via a StatefulWidget, or by using flutter_hooks to create a hidden StatefulElement to observe widget lifecycles.
