Yes, even for Xamarin form

In xamarin, I have initialised the variables which are storing the data but still the same error after deployment of the app in the mobile

@@sayanabharati6548 Please try to put the breakpoint and run it to see where the error is coming from, or share with me that block of code

@@lumbochengebin public partial class MainPage : ContentPage { private string gatewayIpAddress = string.Empty; private string routerSSID = string.Empty; private string routerPassword = string.Empty; public MainPage() { InitializeComponent(); } private async void ScanGatewayQR_Clicked(object sender, EventArgs e) { try { var scanner = new MobileBarcodeScanner(); var result = await scanner.Scan(); if (result != null && !string.IsNullOrEmpty(result.Text)) { gatewayIpAddress = ExtractIpAddressFromQR(result.Text); await DisplayAlert("Gateway QR Scanned", $"Gateway IP Address: {gatewayIpAddress}", "OK"); } else { await DisplayAlert("Error", "Failed to scan Gateway QR code", "OK"); } } catch (Exception ex) { await DisplayAlert("Error", ex.Message, "OK"); } } private async void ScanRouterQR_Clicked(object sender, EventArgs e) { try { var scanner = new MobileBarcodeScanner(); var result = await scanner.Scan(); if (result != null && !string.IsNullOrEmpty(result.Text)) { (routerSSID, routerPassword) = ExtractSSIDAndPasswordFromQR(result.Text); await DisplayAlert("Router QR Scanned", "Scanned successfully!", "OK"); } else { await DisplayAlert("Error", "Failed to scan Router QR code", "OK"); } } catch (Exception ex) { await DisplayAlert("Error", ex.Message, "OK"); } }
