using Microsoft.Extensions.Logging; Create a logger instance in your class: private readonly ILogger _logger = LoggerFactory.Create(builder => builder.AddConsole()).CreateLogger (); private void OnScanResult(Result result) { // Log a debug message _logger.LogDebug("OnScanResult triggered."); // Your existing code for handling the scan result goes here // ... // Log additional information if needed _logger.LogDebug($"Scanned data: {result.Text}"); }

Open the code file or script where you have implemented the ZXing camera functionality. Look for the section of code where the OnScanResult event is handled or subscribed to. Insert logging or debug messages at key points in the code to track the flow of execution and identify any issues. For example, you can use console.log statements in JavaScript or print statements in other programming languages. Specifically, you can add a log message within the event handler for the OnScanResult event to check if it is being triggered when you navigate back to the page. For example: javascriptCopy code // Inside the event handler function for OnScanResult console.log("OnScanResult event triggered"); Run your application and reproduce the issue where the camera stops after scanning three or four times. Monitor the console or debug output to see if the log message appears when you expect it to. If the log message does not appear, it indicates that the OnScanResult event is not being triggered correctly. Based on the log messages, you can narrow down the possible causes of the issue. It could be related to the navigation flow, event subscription, or any other relevant code logic.
