UI is not updating after scan result completed in Nativescript-angular

[monicaarepo]

I am developing android and ios app using nativescript-angular. I am using this plugin in my application. I have an issue after scan result completed the UI are not updated.
My code:

onScanResult(index,status){
     console.log("onScanResult :"+index);
     if(isAndroid){
         this.barcodeScanner.hasCameraPermission().then(
             function(granted) {
               // if this is 'false' you probably want to call 'requestCameraPermission' now
               console.log("Has Camera Permission? " + granted);
             }
         );
        
         // if no permission was granted previously this wil open a user consent screen
         this.barcodeScanner.requestCameraPermission().then(
             function() {
               console.log("Camera permission requested");
             }
         );
     }
     let that=this;
     this.barcodeScanner.scan({
         formats: "QR_CODE",
         cancelLabel: "EXIT. Also, try the volume buttons!",
         cancelLabelBackgroundColor: "#333333", 
         message: "Use the volume buttons for extra light", 
         showFlipCameraButton: true,
         preferFrontCamera: false,
         showTorchButton: true,
         beepOnScan: true,
         torchOn: false, 
         closeCallback: function () {
              console.log("Scanner closed"); 
         },

         orientation: "landscape",
         openSettingsIfPermissionWasPreviouslyDenied: true
     }).then((result) => {
           //UI update function
           this.CheckFunction();
       }, (errorMessage) => {
         console.log("No scan. " + errorMessage);
       }
     );
 }

Help me to fix the issue.

Have you tried wrapping that this.CheckFunction bit in a little timeout or ngzone?

[monicaarepo]

I have tried timeout function but it was not working
My Code is:

 setTimeout(function(){
       this.CheckFunction()
  },3000);

any other solution

[EddyVerbruggen]

I gave you another suggestion actually :)

[monicaarepo]

I have a listview when I click the particular list in the listview I will open the QRcode scanner and I will scan the QRcode, based on the QRcode result I will update the particular cell, but QRcode result is not updated my listview cell.

Did you try using NgZone per my suggestion? If so, please share a repo (playground would be best) that reproduces this.

[monicaarepo]

ok, I will share my code in the playground.
