class Customer {
Customer({
#required this.data,
#required this.status,
});
List<Datum> data;
int status;
factory Customer.fromRawJson(String str) => Customer.fromJson(json.decode(str));
String toRawJson() => json.encode(toJson());
factory Customer.fromJson(Map<String, dynamic> json) => Customer(
data: json["data"] == null ? null : List<Datum>.from(json["data"].map((x) => Datum.fromJson(x))),
status: json["status"] == null ? null : json["status"],
);
Map<String, dynamic> toJson() => {
"data": data == null ? null : List<dynamic>.from(data.map((x) => x.toJson())),
"status": status == null ? null : status,
};
}
class Datum {
Datum({
#required this.id,
#required this.name,
#required this.contactPersonName,
#required this.mobileNo,
#required this.whatsAppNo,
#required this.user,
#required this.address,
#required this.gstNo,
#required this.creaditPeriod,
#required this.note,
#required this.created,
#required this.modified,
#required this.contactPersonEmail,
});
String id;
String name;
dynamic contactPersonName;
dynamic mobileNo;
dynamic whatsAppNo;
dynamic user;
dynamic address;
dynamic gstNo;
dynamic creaditPeriod;
dynamic note;
dynamic created;
dynamic modified;
dynamic contactPersonEmail;
factory Datum.fromRawJson(String str) => Datum.fromJson(json.decode(str));
String toRawJson() => json.encode(toJson());
factory Datum.fromJson(Map<String, dynamic> json) => Datum(
id: json["id"] == null ? null : json["id"],
name: json["name"] == null ? null : json["name"],
contactPersonName: json["contactPersonName"],
mobileNo: json["mobileNo"],
whatsAppNo: json["whatsAppNo"],
user: json["user"],
address: json["address"],
gstNo: json["gstNo"],
creaditPeriod: json["creaditPeriod"],
note: json["note"],
created: json["created"],
modified: json["modified"],
contactPersonEmail: json["contactPersonEmail"],
);
Map<String, dynamic> toJson() => {
"id": id == null ? null : id,
"name": name == null ? null: name,
"contactPersonName": contactPersonName,
"mobileNo": mobileNo,
"whatsAppNo": whatsAppNo,
"user": user,
"address": address,
"gstNo": gstNo,
"creaditPeriod": creaditPeriod,
"note": note,
"created": created,
"modified": modified,
"contactPersonEmail": contactPersonEmail,
};
}
Any idea how to create small object with id and name parameters only.

Answer 1

Just include the parameters you need from the json to the Model.
For example:
class Datum {
final String name;
final String id;
Datum({this.name,this.id});
}
