how to pass provider classname as an argument?

Question

I want to pass provider classname as an argument but it keeps giving me error The name 'providerClassName' isn't a type so it can't be used as a type argument.

I am trying this

  Widget buildText<T>({@required T providerClassName}) {
    return Text(
        Provider.of<providerClassName>(context, listen: false).username);
  }

and i am calling function like this

 buildText(providerClassName: HomeScreenProvider);

Answer 1

You almost got it correct. You have the generic type T of the method

buildText<T extends HomeScreenProvider>

so you can use it like Provider.of<T>(context, listen: false).username and call it
buildText<HomeScreenProvider>();
