PowerApps - Bar Code Scanner Control Parameterizing

I need some kind of help or guide for the Bar Code application, its that I want to parameterize my Scan Button,

like if the user selects the Prefix "S" which means he will only scan Serial Codes. and if the user selects Prefix "LS or 1S" which means he will only scan Product Code along with Serial and than patch both of the values in respective columns like in Serial Code and Product Code Column. and so on.

This will help to control the Bar Code Scanner control, and if the user selected Prefix "S", and it scans the Product Serial code, than it should get a popup like this is not a Serial Bar Code.

Something like that.

Any Help?

is there any workaround for this kind of requirement because the Bar Code Scanner type is set to Auto, the client don't want to change that, instead they require a dropdown where they can select a prefix and according to that prefix the bar code scanner work accordingly.

Any Help?
