BarcodesDetected fires twice upon reading the barcode - .NET MAUI android app #110

I've added in the barcode scanning code to my .NET Maui android application, followed all of the instructions, and the BarcodesDetected event fires twice upon scanning.

What I need to do is capture the value, and then navigate to another page (pass the result value). I have two windows that open as noted above, it fires twice.

Is there a way to have it fire only once?

Thank you.

Same problem. Framework .net 7.0

I solved this problem with a check on a boolean variable. On the first call, I check if this variable is false, and then I set it to true, and I no longer process subsequent requests.
