class OrderePostModel {
  OrderePostModel({
    this.id,
    this.itemsTbId,
    this.accessoriesTbId,
    this.userTbId,
    this.waitingTime,
    this.isReady,
    this.isWaiting,
    this.isClosed,
  });

  String? id;
  String? itemsTbId;
  String? accessoriesTbId;
  String? userTbId;
  String? waitingTime;
  bool? isReady;
  bool? isWaiting;
  bool? isClosed;

  factory OrderePostModel.fromJson(Map<String, dynamic> json) =>
      OrderePostModel(
        id: json["id"],
        itemsTbId: json["itemsTBId"],
        accessoriesTbId: json["accessoriesTBId"],
        userTbId: json["userTBId"],
        waitingTime: json["waitingTime"],
        isReady: json["isReady"],
        isWaiting: json["isWaiting"],
        isClosed: json["isClosed"],
      );

  Map<String, dynamic> toJson() => {
        "id": id,
        "itemsTBId": itemsTbId,
        "accessoriesTBId": accessoriesTbId,
        "userTBId": userTbId,
        "waitingTime": waitingTime,
        "isReady": isReady,
        "isWaiting": isWaiting,
        "isClosed": isClosed,
      };
}

想在這個列表中添加價值？ 像 itemsTBId = 9;

您可以按如下方式更改模型：

List<String>? itemsTBIds
