Mapping JSON into Class Objects

Question

I am trying to map my JSON file into a class object, and then update the cards based on the newly received JSON.

My JSON structure is like this

 {
          


        

Answer 1

class CardInfo {
  //Constructor
  String id;
  String description;
  String role;
  int score;

  CardInfo.fromJson(Map json) {
    this.id = json['id'];
    this.description = json['description'];
    this.role = json['Role'];
    this.score = json['score'];
  }
}

var ci = new CardInfo.fromJson(myJson); 

You can use source generation tools like https://github.com/dart-lang/source_gen https://pub.dartlang.org/packages/json_serializable to generate the serialization and deserialization code for you.

If you prefer using immutable classes https://pub.dartlang.org/packages/built_value is a good bet.
