未处理的异常：类型“String”不是类型转换中“int”类型的子类型

如何解决未处理的异常：类型“String”不是类型转换中“int”类型的子类型

我使用 hive 作为我的应用程序的数据库，我创建了我的类的适配器，但是当我尝试运行我的应用程序时，我在下面出现了异常....... ………………………………………………………………………………………………………………………………………………………… ………………………………………………………………………………………………………………………………………………………… ………………………………………………………………………………………………………………………………………………………… ...

我共享类及其适配器

part 'subCategoryModel.g.dart';


@HiveType(typeId : 1)
class SubCategoryModel extends HiveObject{
  SubCategoryModel({
    this.subCategoryId,this.subCategoryImagePath,this.subCategoryName,this.categoryColor,this.recipeId,this.ingredients,this.recipePhotoDir,this.recordedVoiceDir});

  @HiveField(0)
  final int categoryColor;
