[我有一个项目列表，当我单击一个项目时，它将转到下一个屏幕，因此当我尝试传递给它时，我可以显示所单击项目的相应详细信息，将整个对象数据传递给下一个页面
这是首页代码颤振视图

和此模型的第一页

DailyModel.fromJson(json, areaName)

Area_Id = json['_Id'].toString(),

第二页模型
class ImageModel {
String id;
String image_path;
String Area_Name;
String Name;
String Created_At;
String image_temp_path;
ImageModel({this.id,this.image_path,this.Created_At,this.Area_Name,this.Name,this.image_temp_path});
ImageModel.fromJson(json, areaName,branchName)
: id = json['_id'].toString(),
image_path = json['image_path'].toString(),
image_temp_path = json['image_temp_path'].toString(),
Created_At = json['Created_At'].toString(),
Name = branchName,
Area_Name = areaName;
}
我确实认为这是正确的ImageModel data = Imagelist[index];
