From the snippet shared I get that you want to use the image on the new page after clicking on the item in grid view.

so in the next page widget's constructor declare something like this

//for stateful
class YourWidgetName extends StatefulWidget{
  final String imagePath;
  YourWidgetName({this.imagePath});
  @override
  _YourWidgetName createState() => _YourWidgetName();
}

class _LoginState extends State<Login> {
  @override
  Widget build(BuildContext context) {
  //you can access imagepath as **widget.imagePath** passed
    return Scafold();
  }
}
 

//for stateless
class YourWidgetName extends StatefulWidget{
  final String imagePath;
  YourWidgetName({this.imagePath});
  @override
  Widget build(BuildContext context) {
  //you can access imagepath as **imagePath** passed
    return Scafold();
  }
}

and in onTap function go for:

onTap: () => 
  Navigator.of(context).push(
    MaterialPageRoute(
      builder: (context) => 
        YourWidgetName(
          imagePath: e)
    )
  )
