SignalR disconnects when put iOS app in background

[nayanAubie]

• I followed the exact code mentioned in the example project.
• When I put the iOS app in the background for around 30 seconds, SignalR disconnects automatically and when I back the app in the foreground again, it shows the log of Reconnecting and Reconnected.
• I've used an iPhone 11 with the release mode app.

i was facing the same issue no one helped so what i did was i just created listner for every 3 second if my hub is disconnected then do reconnect sample code:
import 'dart:async';
import 'package:flutter/material.dart';
import 'package:signalr_core/signalr_core.dart';

void main() {
runApp(MyApp());
}

class MyApp extends StatelessWidget {
@OverRide
Widget build(BuildContext context) {
return MaterialApp(
home: Scaffold(
appBar: AppBar(
title: Text('HubConnection Status Checker'),
),
body: Center(
child: HubConnectionStatusChecker(),
),
),
);
}
}

class HubConnectionStatusChecker extends StatefulWidget {
@OverRide
_HubConnectionStatusCheckerState createState() => _HubConnectionStatusCheckerState();
}

class _HubConnectionStatusCheckerState extends State {
late HubConnection _hubConnection;
late Timer _timer;

@OverRide
void initState() {
super.initState();

// Initialize your HubConnection here
_hubConnection = HubConnectionBuilder()
  .withUrl('your_hub_connection_url')
  .build();

// Start checking the connection status every second
_timer = Timer.periodic(Duration(seconds: 1), (timer) {
  // Check the connection status
  if (_hubConnection.state == HubConnectionState.Connected) {
    print('HubConnection is connected');
  } else {
    print('HubConnection is not connected');
    // Optionally, try to start the connection again
    // _hubConnection.start();
  }
});

}

@OverRide
void dispose() {
// Cancel the timer and dispose the HubConnection
_timer.cancel();
_hubConnection.stop();
super.dispose();
}

@OverRide
Widget build(BuildContext context) {
return Text('Checking HubConnection status...');
}
}

and it worked perfectly now i am not facing this issue
