- BarcodeBatchBasicOverlay
class BarcodeBatchBasicOverlay : DataCaptureOverlay
Added in version 7.0.0
An overlay for SDCDataCaptureView that shows a simple augmentation over each tracked barcode.
To display the augmentations, this overlay must be attached to a DataCaptureView. This can be done by passing this overlay to DataCaptureView.addOverlay().
A user of this class may configure the appearance of the augmentations by implementing BarcodeBatchBasicOverlayListener or by calling setBrushForTrackedBarcode().
For additional information about using this overlay, refer to MatrixScan Get Started guide.
- BarcodeBatchBasicOverlay(mode, style)
BarcodeBatchBasicOverlay(BarcodeBatch mode, {BarcodeBatchBasicOverlayStyle? style})
Added in version 7.6.0
Construct a new BarcodeBatchBasicOverlay. For the overlay to be displayed on screen, it must be added to a DataCaptureView.
- listener
BarcodeBatchBasicOverlayListener? listener
Added in version 7.0.0
The listener which is called whenever a new TrackedBarcode is newly tracked or newly recognized.
Note
Using this listener requires the MatrixScan AR add-on.
- brush
Brush brush
Added in version 7.0.0
The brush applied to recognized tracked barcodes if BarcodeBatchBasicOverlayListener is not implemented.
Setting this brush to null hides all tracked barcodes, unless setBrushForTrackedBarcode() is called.
- view
DataCaptureView? view
Added in version 7.0.0
The view this data capture overlay is attached to. When the data capture overlay is currently not attached to a view, null is returned.
- setBrushForTrackedBarcode(brush, trackedBarcode)
Future<
void> setBrushForTrackedBarcode(Brush? brush, TrackedBarcode trackedBarcode)Added in version 7.0.0
The method can be called to change the visualization style of a tracked barcode. This method is thread-safe, it can be called from any thread. If the brush is null, then no visualization will be drawn for the tracked barcode. Additionally, tapping on the barcode will have no effect - the action defined by BarcodeBatchBasicOverlayListener.didTapTrackedBarcode() callback will not be performed.
Setting a brush for a tracked barcode that is not part of the currently active session will be ignored.
Note
Using this function requires the MatrixScan AR add-on.
- clearTrackedBarcodeBrushes()
Future<
void> clearTrackedBarcodeBrushes()Added in version 7.0.0
Clears all currently displayed visualizations for the tracked barcodes.
This only applies to the currently tracked barcodes, the visualizations for the new ones will still appear.
- shouldShowScanAreaGuides
bool shouldShowScanAreaGuides
Added in version 7.0.0
When set to true, this overlay will visualize the active scan area used for BarcodeBatch. This is useful to check margins defined on the DataCaptureView are set correctly. This property is meant for debugging during development and is not intended for use in production.
By default this property is false.
- style
final BarcodeBatchBasicOverlayStyle style
Added in version 7.0.0
The overlay style. Defaults to Frame.
