BarcodeTracking

class BarcodeTracking : DataCaptureMode

Added in version 6.7.0

Data capture mode that implements MatrixScan (barcode tracking).

Learn more on how to use barcode tracking in our Get Started With MatrixScan guide.

This capture mode uses the barcode scanning and tracking capabilities. It cannot be used together with other capture modes that require the same capabilities, e.g. BarcodeCapture.

BarcodeTracking.forContext(context, settings)

BarcodeTracking.forContext(DataCaptureContext context,
        BarcodeTrackingSettings settings)

Added in version 6.7.0

Constructs a new barcode tracking mode with the provided context and settings.

isEnabled

bool isEnabled

Added in version 6.7.0

Implemented from DataCaptureMode. See DataCaptureMode.isEnabled.

applySettings(settings)

Future<void> applySettings(BarcodeTrackingSettings settings)

Added in version 6.7.0

Asynchronously applies the new settings to the barcode scanner. If the scanner is currently running, the task will complete when the next frame is processed, and will use the new settings for that frame. If the scanner is currently not running, the task will complete as soon as the settings have been stored and won’t wait until the next frame is going to be processed.

Same as applySettings() with the second argument set to null.

addListener(listener)

void addListener(BarcodeTrackingListener listener)

Added in version 6.7.0

Adds the listener to observe this barcode capture instance.

In case the same listener is already observing this instance, calling this method will not add the listener again.

addAdvancedListener(listener)

void addAdvancedListener(BarcodeTrackingAdvancedListener listener)

Added in version 6.14.0

Adds the advanced listener to observe this barcode capture instance.

In case the same listener is already observing this instance, calling this method will not add the listener again.

removeListener(listener)

void removeListener(BarcodeTrackingListener listener)

Added in version 6.7.0

Removes a previously added listener from this barcode tracking instance.

In case the listener is not currently observing this instance, calling this method has no effect.

removeAdvancedListener(listener)

void removeAdvancedListener(BarcodeTrackingAdvancedListener listener)

Added in version 6.14.0

Removes a previously added advanced listener from this barcode tracking instance.

In case the listener is not currently observing this instance, calling this method has no effect.

recommendedCameraSettings

static CameraSettings get recommendedCameraSettings

Added in version 6.7.0

Returns the recommended camera settings for use with barcode tracking.

context

DataCaptureContext? get context

Added in version 6.7.0

Implemented from DataCaptureMode. See DataCaptureMode.context.
