1. Listing layout

hierarchy of the widget

2. Define ProductBox

                  class ProductBox extends StatelessWidget {
                        ProductBox({Key key, this.name, this.description, this.price, this.image}) 
                            : super(key: key); 
                        final String name; 
                        final String description; 
                        final int price; 
                        final String image; 

                        Widget build(BuildContext context) {
                            return Container(
                              padding: EdgeInsets.all(2), height: 120,  child: Card( 
                                  child: Row(
                                    mainAxisAlignment: MainAxisAlignment.spaceEvenly, children: <Widget>[
                                        Image.asset("assets/appimages/" +image), Expanded(
                                          child: Container(
                                              padding: EdgeInsets.all(5), child: Column(
                                                mainAxisAlignment: MainAxisAlignment.spaceEvenly, 
                                                    children: <Widget>[ 
                                                    
                                                    Text(this.name, style: TextStyle(fontWeight: 
                                                      FontWeight.bold)), Text(this.description), 
                                                    Text("Price: " + this.price.toString()), 
                                                ], 
                                              )
                                          )
                                        )
                                    ]
                                  )
                              )
                            );
                        }
                      }

                      

3. Use the ProductBox widget in the MyHomePage widget

                      class MyHomePage extends StatelessWidget { 
   MyHomePage({Key key, this.title}) : super(key: key); 
   final String title; 

   @override  
   Widget build(BuildContext context) {
      return Scaffold(
         appBar: AppBar(title:Text("Product Listing")), 
         body: ListView(
            shrinkWrap: true, padding: const EdgeInsets.fromLTRB(2.0, 10.0, 2.0, 10.0), 
            children: <Widget> [
               ProductBox(
                  name: "iPhone", 
                  description: "iPhone is the stylist phone ever", 
                  price: 1000, 
                  image: "iphone.png"
               ), 
               ProductBox(
                  name: "Pixel", 
                  description: "Pixel is the most featureful phone ever", 
                  price: 800, 
                  image: "pixel.png"
               ), 
               ProductBox( 
                  name: "Laptop", 
                  description: "Laptop is most productive development tool", 
                  price: 2000, 
                  image: "laptop.png"
               ), 
               ProductBox( 
                  name: "Tablet", 
                  description: "Tablet is the most useful device ever for meeting", 
                  price: 1500, 
                  image: "tablet.png"
               ), 
               ProductBox(
                  name: "Pendrive", 
                  description: "Pendrive is useful storage medium", 
                  price: 100, 
                  image: "pendrive.png"
               ), 
               ProductBox(
                  name: "Floppy Drive", 
                  description: "Floppy drive is useful rescue storage medium", 
                  price: 20, 
                  image: "floppy.png"
               ), 
            ],
         )
      );
   }
}
