Dynamic Card with Dynamic Image

Hello everyone
Can you tell me where to find a good example where I can create a dynamic card with a dynamic image inside, let me explain better, I’m making an app where I scan barcodes and for each barcode a dynamic card must be created with the relevant dynamic image of the code scanned, I searched online but I didn’t find anything useful, all the examples I found initialize with a ready list but I don’t need it so trying to imitate it I only get errors.
Thanks everyone and happy programming, bye
