Hi guys, tell me if you guys do need extra information that I have missed.
currently, I have this problem with a future builder, I'm trying to call my future function of future builder inside a scaffold. I will then use a listview builder.
However i am having a problem that I just cannot solve, based on the errors,it seems to indicate that I have duplicated something?
This is my code for SupportTicket class which involved json deserialization.
class SupportTicket {
final String ticket_number;
final String ticket_id;
final String assigned_user;
final String check_in;
final String check_out;
final String check_in_address;
final String check_out_address;
final String subject;
final String created_date;
final String rating;
final String customer_name;
final String equipment_location;
const SupportTicket({
required this.ticket_number,required this.ticket_id,required this.assigned_user,
required this.check_in,required this.check_out,required this.check_in_address, required this.check_out_address,
required this.subject, required this.created_date, required this.rating, required this.customer_name,
required this.equipment_location,
});
static SupportTicket fromJson(Map<String, dynamic> json) => SupportTicket(
// if it returns false, because idontknow, odoo return false for null in JSON,
//then set it as ' ', otherwise, set it as its normal value, which is usually String
ticket_number : json['ticket_number'] == false ? json['ticket_number'] = '' : json['ticket_number'].toString(),
ticket_id : json['id'].toString(),
assigned_user: json['user_id'] == false ? json['user_id'] = '' : json['user_id'][1].toString(),
check_in: json['check_in'].toString(),
check_out: json['check_out'].toString(),
check_in_address: json['check_in_address'].toString(),
check_out_address: json['check_out_address'].toString(),
created_date: json['created_date'] == false ? json['created_date'] = '' : json['created_date'].toString(),
subject: json['subject'] == false ? json['subject'] = '' : json['subject'].toString(),
rating: json['rating'] == null ? json['rating'] = '0' : json['rating'].toString(),
customer_name: json['customer_name'] == null ? json['customer_name'] = 'Not Defined' : json['customer_name'].toString(),
equipment_location: json['equipment_location'] == null ? json['equipment_location'] = 'Not Defined' : json['equipment_location'].toString(),
);
}
This is my API call class which have the future static call, note that i am using odoo RPC here, if anyone is wondering it is an xml-rpc with JSON data called.

return listTicket.map((json) => ResPartner.fromJson(json)).toList();

Below is my buildsupporttickets widget used for listviewbuilder.
Widget buildSupportTickets(List<SupportTicket> supporttickets) =>
ListView.builder(
physics: BouncingScrollPhysics(),
itemCount: supporttickets.length,
controller: scrollcontroller,
itemBuilder: (context, index){
var supportticket = supporttickets[index];
print('is the problem here before getpartnerimage?');
var respartnerlist = AllTicketsApi.getPartnerImage(supportticket.customer_id); //fetch partner image data based on support ticket ID.
print (respartnerlist.toString());
//create a futurebuilder here for respartner, so we will have kind of a nested future builder. i dont know what makes sense anymore, but let us try.
final avatarUrl ='${globalClient.baseURL}/web/image?model=res.partner&field=image_128&id=${supportticket.customer_id}&unique=${respartnerlist}';

With all due respect please tell me if i need to add anything else for you guys reference.
CodePudding user response：
you got the error in the AllTicketsApi class.
change your import From
import '../OdooApiCall_DataMapping//SupportTicket.dart';
To //Replace the double slash(//) with single slash (/)
import '../OdooApiCall_DataMapping/SupportTicket.dart';
