Hello everyone, how are you?
I'm developing an app in MIT App Inventor using two screens.
Screen 1 is ready,
but I'm having trouble with the second screen.
On Screen 2 of my app, I save some objects using the name and link provided by the user, and I wanted to convert this link into a QR code.
My first attempt used the image component, but it doesn't save multiple images, so I thought about saving each QR code within a listview. Does anyone know the best way to do this?
thanks
Note: I'm saving this information with Firebase.

I did this to create dynamic images, but when I ran it for testing, the error com.google.appinventor.components.runtime.imagem appeared.
Any idea what it could be?
Is an alphanumeric id allowed?
Check the documentation of that extension
Try a numeric value as id
