        return Card(
          margin: EdgeInsets.all(10),
          child: Column(
            children: <Widget>[
              AspectRatio(
                aspectRatio: 20/9,
                child: Image.network(value["imageUrl"], fit: BoxFit.cover,),
              ),
              ListTile(
                leading: CircleAvatar(
                  backgroundImage: NetworkImage(value["imageUrl"]),
                ),
                title: Text(value["title"]),
                subtitle: Text(value["author"]),
              )
