my trouble is, how to call, viewmodel at initState(), here my sample code https://github.com/pratamawijaya/Flutter101/blob/master/flutter_project/flutter_news_mvvmprovider/lib/ui/screens/home_screen.dart#L34
when I'm trying to get currentPage, it doesn't increased

firstly, the point of the view model is to move all your business logic out of the view and manage all your state in the model. Your code is not following the architecture, there should be no business logic in your view.
In your scroll listener all you should have is
model.requestNextPageData();
When you reach your max scroll limit.
If you want to call something when the view is initialised use initState. Unfortunately I won't be able to review your code for you. You have to remove all logic from your view file, that's what the model is there for. You can't be managing state in two different places, it'll become too hard to maintain.
