Properties
- hashCode → int
-
The hash code for this object.
no setterinherited
- key → Key?
-
Controls how one widget replaces another widget in the tree.
finalinherited
- onDetectedImageTapped → void Function(String? imageName)?
-
Called when a marker for detected reference image is tapped.
final
- onError → void Function(String error)?
-
Called when the view encounters an error.
final
- onImageDetected → void Function(String? imageName)
-
Called when one of the reference images is detected in the current camera
stream.
final
- onRecognitionPaused → VoidCallback?
-
iOS only; called when the view becomes invisible in the current context
(e.g. after navigating to another Route).
final
- onRecognitionResumed → VoidCallback?
-
iOS only; called when the view is restored after being paused (e.g. after
navigating to the Route with the view).
final
- onRecognitionStarted → VoidCallback?
-
Called when all reference images are loaded to the recognition module and
the view starts the detection.
final
- onViewCreated → void Function(ARQuidoViewController controller)?
-
Callback method for when the view is ready to be used.
final
