I want to build a scanner where I scan different labels (handdrawn or printed, with text and numbers on it, possibly in different colors) and want to call a hook everytime I "see" specific types of items on these labels, e.g. a title and a price.
I tried the solution hinted at in https://community.flutterflow.io/ask-the-community/post/text-extraction-ocr-from-camera-stream-GHY23H1X8OinQfQ
It compiles, but on the web ("Test Mode") no permission for the camera is requested, but in the console there are errors that this permission is missing.
I therefore gave that permission manually to the website, and these errors vanished, but still I am not able to see any camera stream.
This is the console output when I open the BottomSheet (screenshot), which only consists of the custom widget (100% width and height) defined in the post mentioned above:
camera_service.dart:37 [Violation] Permissions policy violation: camera is not allowed in this document.errors.dart:288 Uncaught (in promise) DartError:
