                    {
                        _scanPage.IsScanning = false;

                        Device.BeginInvokeOnMainThread(() =>
                        {
                            Navigation.PopAsync();
                            DisplayAlert("Scanned Barcode", result.Text, "OK");
                        });
                    };
                }

                await Navigation.PushAsync(_scanPage).ConfigureAwait(true);
            }
            catch (Exception)
            {
                return;
            }
        }

The Plugin Details are below

ZXing.Net.Mobile 2.4.1 and ZXing.Net.Mobile.Forms 2.4.1

please suggest me is there is any other plugin which we can use instead

Answer 1

 updated the Initialize scanner code in Main Activity, below are the code 
global::Xamarin.Forms.Forms.Init(this, bundle);
            //-->Initialize scanner
            MobileBarcodeScanner.Initialize(this.Application);

and it work fine now
