i cannot compare the value barcode, with a simple String.

String barcode = await BarcodeScanner.scan(); if(barcode == '1'){ I do not know why, but if I log the qrcode in the Terminal it show "1" so it have to be true, but the code do not go inside, that if statement.

thanks in advanced

what error do you get?

Sorry I forgot to close that issue, the issue was, that the Qrcode had a speace at the End. So in ther Terminal "1" and "1 " looks the same, but it isn't :). So for anyone you have the same Problem with string comparison, checking the length of the String, might be a good idea.
