feedbackForBarcode(barcode)

feedbackForBarcode?(barcode: Barcode): SparkScanBarcodeFeedback | null

Added in version 6.23.0

Invoked for each detected barcode. The implementation should return SparkScanBarcodeFeedback.Success, SparkScanBarcodeFeedback.Error, or null. If null is returned, the default brush is used to visualize the barcode and no other feedback (visual, sound, or haptic) is emitted. By default returns SparkScanBarcodeFeedback.Success. Note that this method is executed on a background thread.
