Hi there!
I'm playing with 2D QR Codes. And i'm facing the first problem with the content value. So, i want to put a FirebaseDocumentReference into the code. Seems easy: i add a QR code and straight to the value field:
Yeah, but:
Then i tought that maybe a 'Document Reference' type doesn't fit into, so i created a custom function to return a DocumentReference.toString(); and tried again. But it continue to fail.
It seems that i can only pass a 'fixed' or 'hardcoded' string?
Is there anyway to pass a firebase field to the QR Code value content?
Thanks in advance.
