    I use this  
final List<Products> products = productsJson.map((productJson) => 
Products.fromJson(productJson)).toList();   
insteed of 
return Products(
      id: e["id"],
      title: e["title"],
      price: e["price"],
      description: e["description"],
      category: e["category"],
      image: e["image"],
      rating: Rating.fromJson(e["rating"]),
    );
  }).toList();
and error gone

    Your Rating class like this :

    Rating{
final double xyz;
}

    Change Rating class like this :
    double to int

     Rating{
final int xyz;
}

    if this is not working then check api response and parameters datatype.
