// create a new class
class JsonStringToInt implements JsonConverter<int, dynamic> {
  const JsonStringToInt();

  @override
  int fromJson(dynamic json) {
    if (json is num) {
      return json.toInt();
    }
    return int.tryParse(json) ?? 0;
  }

  @override
  String toJson(int object) => object.toString();
}

// and use in your model class as annotation like this
@JsonSerializable()
@JsonStringToInt()
class Product {
  final int? price;
 
 const Product({this.price});
 factory Product.fromJson(Map<String, dynamic> json) => _$ProductFromjson(json);
}
