Is there any way to use viewModel in didUpdateWidget?

When the arguments received from the widget changed, we wanted to clear the existing listener for the pagingController and populate a new one. How can i do this?

```dart
@override
void didUpdateWidget(convariant MyWidget oldWidget) {
super.didUpdateWidget(oldWidget);

if (oldWidget.path != widget.path) {
_pagingController.removePageRequestListener(_pageRequestListener!);
_pageRequestListener = null;

_pageRequestListener = (pageKey) async {
// This is where we use viewModel.
}

_pagingController.addPageRequestListener(_pageRequestListener!);
_pagingController.refresh();
}
}
```
