Flutter: Adding inkwell to my gridlist in order to use ontap () is throwing errors

Code is fine until I try and add inkwell()

''' return Scaffold( appBar: AppBar( title: const Text("App Dev and QA process"), centerTitle: true, systemOverlayStyle: SystemUiOverlayStyle.dark), body: AnimationLimiter(

I'm trying to add onTap() so each grid block takes me to another page.

Errors are:

1. The body might complete normally, causing 'null' to be returned, but the return type, 'Widget', is a potentially non-nullable type.
2. Unexpected text 'return'.
3. Too many positional arguments: 0 expected, but 1 found.

Move return outside of Inkwell and add child to it.

List.generate(
  8,
      (int index) {
    return InkWell(
      child: AnimationConfiguration.staggeredGrid(),
      onTap: () {},
    );
  }
)
