按dart中的两个属性分别以升序和降序对List<object>排序

int customComparator(Object object1, Object object2) {
  // 获取object1和object2的属性值
  var property1Object1 = object1.property1;
  var property1Object2 = object2.property1;
  var property2Object1 = object1.property2;
  var property2Object2 = object2.property2;
  
  // 按照property1进行升序排序
  if (property1Object1.compareTo(property1Object2) != 0) {
    return property1Object1.compareTo(property1Object2);
  }
  
  // 按照property2进行降序排序
  return property2Object2.compareTo(property2Object1);
}

List<Object> objects = [...]; // 替换为实际的Object列表

objects.sort(customComparator);
