flutter - 在颤振或飞镖中将数据插入数组sharedpref

Question

如何将数据输入保存到数组？

我有代码，所以我创建了一个存储在存储中的输入，我创建了一个数据提交函数，它是句柄保存，

handlesave() async {
    SharedPreferences ref = await SharedPreferences.getInstance();
          var idU = user.user.id;
          final dataJ = JobStorageModel(
            iduser: idU.toString(),
            id: widget.job.id,
            job_title: widget.job.job_title,
            location: widget.job.location,
          );
          String json = jsonEncode(dataJ);
          print('save -> $json');
          ref.setString('bookmark', json);
}

这是我做的模型

class JobStorageModel {
  int id;
  String iduser;
  String job_title;
  String location;

  JobStorageModel({
    this.id,
    this.iduser,
    // ignore: non_constant_identifier_names
    this.job_title,
    this.location,
  });

  JobStorageModel.fromJson(Map<String, dynamic> json) {
    this.id = json['ID'];
    this.iduser = json['iduser'];
    this.job_title = json['job_title'];
    this.location = json['location'];
  }

  Map<String, dynamic> toJson() {
    return {
      'ID': this.id,
      'iduser': this.iduser,
      'job_title': this.job_title,
      'location': this.location,
    };
  }
}

如何容纳输入？
