我试图加载数组 json（没有键的数组）并获取到对象列表中，这是我的示例代码：

我的 ApiCliet ：

Future<List<OnBoardingModel>> fetchOnboarding() async {
    try {
      Response response = await dio.get("api/OnboardingItem");
      return OnBoardingModel.fromJson(response.data) as List;
    } catch (error, stacktrace) {
      throw Exception("Exception occured: $error stackTrace: $stacktrace");
    }
  }

我的对象（使用quicktype生成）：

List<OnBoardingModel> onBoardingModelFromJson(String str) => List<OnBoardingModel>.from(json.decode(str).map((x) => OnBoardingModel.fromJson(x)));

String onBoardingModelToJson(List<OnBoardingModel> data) => json.encode(List<dynamic>.from(data.map((x) => x.toJson())));

class OnBoardingModel {
  OnBoardingModel({
    this.id,
    this.judul,
    this.deskripsi,
    this.urlGambar,
  });

  int id;
  String judul;
  String deskripsi;
  String urlGambar;

  factory OnBoardingModel.fromJson(Map<String, dynamic> json) => OnBoardingModel(
    id: json["id"],
    judul: json["judul"],
    deskripsi: json["deskripsi"],
    urlGambar: …
