flutter : provider is not updating UI and Not Clearing the variables - flutter

Question

This is my Query provider
In this provider My data is not updating UI not clearing variable of this function clearRaisedQueryDetailsLoad()
import 'dart:developer';
import 'package:flutter/material.dart';
class QueryProvider with ChangeNotifier {
//raised query details
bool _isRaisedQueryDetailsLoad = false;
bool get isRaisedQueryDetailsLoad => _isRaisedQueryDetailsLoad;
List _raisedQueryDetailsData = [];
List get raisedQueryDetailsData => _raisedQueryDetailsData;
var _raisedQueryDetailsSubject = '';
String get raisedQueryDetailsSubject => _raisedQueryDetailsSubject;
var _raisedQueryDetailsAttachmentUrl = '';
String get raisedQueryDetailsAttachmentUrl =>
_raisedQueryDetailsAttachmentUrl;
var _raisedQueryDetailsStatus;
dynamic get raisedQueryDetailsStatus => _raisedQueryDetailsStatus;
void addIsRaisedQueryDetailsLoad(bool isRaisedQueryDetailsLoad1) async {
_isRaisedQueryDetailsLoad = isRaisedQueryDetailsLoad1;
notifyListeners();
}
void addRaisedQueryDetailsData(dynamic raisedQueryDetailsData1) async {
for (int i = 0; i < raisedQueryDetailsData1["query_details"].length; i++) {
_raisedQueryDetailsData.add(raisedQueryDetailsData1["query_details"][i]);
}
_raisedQueryDetailsSubject = raisedQueryDetailsData1["query_subject"];
_raisedQueryDetailsAttachmentUrl = raisedQueryDetailsData1["attachment_url"];
_raisedQueryDetailsStatus = raisedQueryDetailsData1["query_status"];
print("_raisedQueryDetailsData $_raisedQueryDetailsData");
print("_raisedQueryDetailsAttachmentUrl $_raisedQueryDetailsAttachmentUrl");
print("_raisedQueryDetailsStatus $_raisedQueryDetailsStatus");
print("_raisedQueryDetailsData ${_raisedQueryDetailsData.runtimeType}");
print("_raisedQueryDetailsData ${_raisedQueryDetailsData.length}");
notifyListeners();
}
getRaisedQueryDetailsData() {
return _raisedQueryDetailsData;
}
getRaisedQueryDetailsDataStatus() {
return _raisedQueryDetailsStatus;
}
getRaisedQueryDetailsDataAttachment() {
return _raisedQueryDetailsAttachmentUrl;
}
getIsRaisedQueryDetailsLoad() {
print(_isRaisedQueryDetailsLoad);
return _isRaisedQueryDetailsLoad;
}
getIsRaisedQueryDetailsSubject() {
return _raisedQueryDetailsSubject;
}
void clearRaisedQueryDetailsLoad() {
print("clear");
_raisedQueryDetailsStatus = null;
_raisedQueryDetailsSubject = '';
_raisedQueryDetailsAttachmentUrl = '';
_raisedQueryDetailsData.clear();
notifyListeners();
}
}
queryProvider.clearRaisedQueryDetailsLoad(); // Here When I am calling this api fuction multiple time then my provider data is storing duplicate data(This function is bellow)
and second issue is when I am calling raisedQueryDetailsApiCalled() this function from a dialog box then My UI data is not changing
QueryProvider queryProvider = QueryProvider();
#override
void initState() {
WidgetsBinding.instance.addPostFrameCallback((timeStamp) {
queryProvider = Provider.of<QueryProvider>(context, listen: false);
});
// TODO: implement initState
super.initState();
print(widget.queryData["id"]);
raisedQueryDetailsApiCalled();
}
raisedQueryDetailsApiCalled() async {
queryProvider.clearRaisedQueryDetailsLoad(); // Here When I am calling this api fuction multiple time then my provider data is storing duplicate data
if (mounted) {
setState(() {
queryProvider.addIsRaisedQueryDetailsLoad(true);
});
}
apiManager.queryRaisedDetailsApi(context, widget.queryData["id"]).then(
(val) {
if (val["code"] == 200) {
setState(() {
queryProvider.addRaisedQueryDetailsData(val["data"]);
});
}
if (mounted) {
setState(() {
queryProvider.addIsRaisedQueryDetailsLoad(false);
});
}
},
);
}
This is my UI code
queryProvider.getIsRaisedQueryDetailsLoad()
? SingleChildScrollView(
child: Column(
children: [
ProductListSkeleton(),
ProductListSkeleton(),
ProductListSkeleton(),
ProductListSkeleton(),
ProductListSkeleton(),
ProductListSkeleton()
],
),
)
: queryProvider1.getRaisedQueryDetailsData().length == 0
? Container(
child: Center(
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
crossAxisAlignment: CrossAxisAlignment.center,
children: [Text("Data not available")],
),
),
)
: Column(
children: [
_bodyChat(queryProvider1),
],
),

Try using the getter methods you have already instead of the general methods and see how that works. And maybe for the widgets code try to make use of consumers.
Consumer Class - provider library
