IOS camera gets stuck when exit (OnStop) the application and come back (OnStart) [BUG]

[Chakib-Temal]

Describe the bug there is a bug which occurs only on the IOS and not on android when i launch the app, everything is fine but once I exit the application (OnStop) and come back afterwards (OnStart) (so without complete closing), the camera gets stuck and the QrView displays last image camera detected before exiting the application

this error exists only on Ios and not on Android

Information build Stable Flutter 1.22.0

• Device: Iphone SE 2020
• OS: IOS 14.4.2

temporary solution implements WidgetsBindingObserver to use widget lifecycle events and refresh your page

class PageState extends State<HomePage> with WidgetsBindingObserver {

@override
  void initState() {
    super.initState();
    WidgetsBinding.instance.addObserver(this);
  }

/// imlementation WidgetsBindingObserver
@override
  void didChangeAppLifecycleState(AppLifecycleState state) async{
    super.didChangeAppLifecycleState(state);
    if (state == AppLifecycleState.resumed) {
       refreshPage();
    }
  }

@override
  void dispose() {
    super.dispose();
    WidgetsBinding.instance.removeObserver(this);
  }
}

I have the same problem on an iPhone 6s with iOS 13.5.1.

Thank you very much for the temporary solution, it works great for now!
