I've an api that return some data. I only need to fetch dish data from the api. The issue is while I'm getting data from the api response, the first dish data is only saving to iteratable list.
EDIT
I can't fetch the data from Iterable List
the api is like below

there is a data category called addonCat in the api, I need this to be ignored and go on to the next dish when fetching data from the response.
api_model.dart this where I'm fetching the data from response of api
class CategoryDishes {
final String dishId;
final String dishName;
final double dishPrice;
final String dishImage;
final String dishCurrency;
final double dishCalories;
final String dishDescription;
final bool dishAvailability;
final double dishType;
final String nexturl;
//final List<AddonCat> _addonCat;
CategoryDishes(
{this.dishId,
this.dishName,
this.dishPrice,
this.dishImage,
this.dishCurrency,
this.dishCalories,
this.dishDescription,
this.dishAvailability,
this.dishType,
this.nexturl});
factory CategoryDishes.fromJson(Map<String, dynamic> json) {
return CategoryDishes(
dishId: json['dish_id'],
dishName: json['dish_name'],
dishPrice: json['dish_price'].toDouble(),
dishImage:
json['dish_image'] ?? Constants.FOOD_PLACEHOLDER_IMAGE_ASSET_URL,
dishCurrency: json['dish_currency'],
dishCalories: json['dish_calories'].toDouble(),
dishDescription: json['dish_description'],
dishAvailability: json['dish_Availability'],
dishType: json['dish_Type'].toDouble(),
nexturl: json['nexturl']);
}
static Resource<List<CategoryDishes>> get all {
return Resource(
url: Constants.FOOD_API_URL,
parse: (response) {
final result = json.decode(response.body.toString());
// print(response);
Iterable list = result[0]['table_menu_list'][0]['category_dishes'];
debugPrint("=========== Dish_List ==============\n" + list.toString());
debugPrint("====================================");
return list.map((model) => CategoryDishes.fromJson(model)).toList();
});
}
}
web.service.dart
class Resource<T> {
final String url;
T Function(Response response) parse;
Resource({this.url, this.parse});
}
class Webservice {
Future<T> load<T>(Resource<T> resource) async {
final response = await http.get(resource.url);
if (response.statusCode == 200) {
// debugPrint("------D------>\n" + response.body);
return resource.parse(response);
} else {
throw Exception('Failed to load data!');
}
}
}
main.dart

Now I can save the data to the Iterable List, but can't fetch data from the list to the card elements. Above main.dart is the place where I'm fetching the data.
How to achieve this?
EDIT
I'm only able to get the first part of the dishlist in the api, after the first category there is many of the dishes are available, I need to fetch all of the dishlist and display it to the corresponding tabs, refer above api link to know how the api is.
Any suggestions would be helpful.

Step 1: Create a project in Vs code, And remove the default code. Step 2: Before writing the code just add the HTTP plugin in your pubspec yaml file. Step 3: In main. dart file call the main() function , inside it run the runApp( ) method and give it an App (MyApp).
Its actually saving the data. But its not printing on the console when using debugPrint.
You have to give wrapWidth in debugPrint, so that you can see full response stored in a variable.
debugPrint(
"=========== Dish_List ==============\n" + list.toString(),
wrapWidth: 1000,
);
debugPrint("====================================");
I think this is the problem you are facing.
You can also do pretty-print to make it understandable
debugPrint(
"=========== Dish_List ==============",
);
JsonEncoder encoder = new JsonEncoder.withIndent(' ');
debugPrint('${encoder.convert(list)}', wrapWidth: 1000);
debugPrint("====================================");
