Dart将List<Model>转换为另一个List<another>

修复:修复了非DTO模型中的导入路径,谢谢大家。哦,我的天哪,linter仍然使用CTRL+左键单击将我导航到文件

大家好,今天好。

dart给出了这个奇怪的错误,我只是将我的dto从API转换为我的模型。

var salesCategoriesDto =
        dataList.map((i) => SalesDailyCategoryResponseDto.fromJson(i)).toList();

var salesCategories = salesCategoriesDto
        .map((i) => SalesDailyCategory.fromDto(salesCategoryDto: i))
        .toList();

传递迭代对象时出错
错误跟踪消息 迭代项给出的错误就好像“不能通过或类型错误”。我是不是错过了什么?

销售每日类别响应Dto.dart

class SalesDailyCategoryResponseDto {
  String? lineGroup;
  int? daySales;
  int? monthSales;
  int? yearSales;
  int? totalSales;

  SalesDailyCategoryResponseDto._({
    required this.lineGroup,
    required this.daySales,
    required this.monthSales,
    required this.yearSales,
    required this.totalSales,
  });

  factory SalesDailyCategoryResponseDto.fromJson(Map<String, dynamic> jsonObject) {
    return SalesDailyCategoryResponseDto._(
      lineGroup: jsonObject["LineGroup"],
      daySales: jsonObject["DaySales"],
      monthSales: jsonObject["MonthSales"],
      yearSales: jsonObject["YearSales"],
      totalSales: jsonObject["TotalSales"],
    );
  }
}

SalesDailyCategory.dart

class SalesDailyCategory {
  String lineGroup;
  int daySales;
  int monthSales;
  int yearSales;
  int totalSales;

  SalesDailyCategory._({
    required this.lineGroup,
    required this.daySales,
    required this.monthSales,
    required this.yearSales,
    required this.totalSales,
  });

  factory SalesDailyCategory.fromDto(
          {required SalesDailyCategoryResponseDto salesCategoryDto}) =>
      SalesDailyCategory._(
        lineGroup: salesCategoryDto.lineGroup!,
        daySales: salesCategoryDto.daySales!,
        monthSales: salesCategoryDto.monthSales!,
        yearSales: salesCategoryDto.yearSales!,
        totalSales: salesCategoryDto.totalSales!,
      );
}

我用的是飞镖3.4.1

我试着不使用私有构造函数,结果仍然是一样的,而且当使用i上的点时,linter知道它引用了SalesDailyCategoryResponseDto

错误:无法将参数类型“SalesDailyCategoryResponseDto(其中SalesDailyCatalogyResponse dto是在D:\workcode\redated\lib\features\sales\persentation\dtos\sales_daily_category_response_dto.dart中定义的)”分配给参数类型“sales DailyCategory ResponseD to(其中,SalesDaily分类响应D to是在D:\workcode\redated\lib\features\sales \persentation\dstos\sales_daily_category_response_dto.dart中定义的。)”。(argument_type_not_assignable at[eth_sales_management_system]lib\features\sales\repository\sales_daily_prepository.dart:39)
