widgetForCapturedLabel(overlay, capturedLabel)

Future<LabelCaptureAdvancedOverlayWidget?> widgetForCapturedLabel(
        LabelCaptureAdvancedOverlay overlay,
        CapturedLabel capturedLabel)

Added in version 7.2.0

View to be drawn corresponding to the given CapturedLabel. This method will be called before anchorForCapturedLabel() and offsetForCapturedLabel(). Called from the main thread. Beware that this view can be overridden with LabelCaptureAdvancedOverlay.setWidgetForCapturedLabel() method. This method will only be called for new tracked labels that do not have a view yet, e.g. a view set by a call to LabelCaptureAdvancedOverlay.setWidgetForCapturedLabel().

anchorForCapturedLabel(overlay, capturedLabel)

Future<Anchor> anchorForCapturedLabel(
        LabelCaptureAdvancedOverlay overlay,
        CapturedLabel capturedLabel)

Added in version 7.2.0

Anchor point that should be used for the view corresponding to the given CapturedLabel. This method will be called after widgetForCapturedLabel() and before offsetForCapturedLabel(). Called from the main thread. Beware that this anchor can be overridden with LabelCaptureAdvancedOverlay.setAnchorForCapturedLabel() method. This method will only be called for new tracked labels that do not have an anchor yet, e.g. an anchor set by a call to LabelCaptureAdvancedOverlay.setAnchorForCapturedLabel().

offsetForCapturedLabel(overlay, capturedLabel)

Future<PointWithUnit> offsetForCapturedLabel(
        LabelCaptureAdvancedOverlay overlay,
        CapturedLabel capturedLabel)

Added in version 7.2.0

Offset to be set to the view corresponding to the given CapturedLabel. The offset is relative to the anchor point of the tracked label. This method will be called after widgetForCapturedLabel() and anchorForCapturedLabel(). Called from the main thread. Beware that this offset can be overridden with LabelCaptureAdvancedOverlay.setOffsetForCapturedLabel() method. This method will only be called for new tracked labels that do not have an offset yet, e.g. an offset set by a call to LabelCaptureAdvancedOverlay.setOffsetForCapturedLabel().

widgetForCapturedLabelField(overlay, labelField)

Future<LabelCaptureAdvancedOverlayWidget?> widgetForCapturedLabelField(
        LabelCaptureAdvancedOverlay overlay,
        LabelField labelField)

Added in version 7.2.0

View to be drawn corresponding to the given LabelField. This method will be called before anchorForCapturedLabelField() and offsetForCapturedLabelField(). Called from the main thread. Beware that this view can be overridden with LabelCaptureAdvancedOverlay.setWidgetForCapturedLabelField() method. This method will only be called for new tracked fields that do not have a view yet, e.g. a view set by a call to LabelCaptureAdvancedOverlay.setWidgetForCapturedLabelField().

anchorForCapturedLabelField(overlay, labelField)

Future<Anchor> anchorForCapturedLabelField(
        LabelCaptureAdvancedOverlay overlay,
        LabelField labelField)

Added in version 7.2.0

Anchor point that should be used for the view corresponding to the given LabelField. This method will be called after widgetForCapturedLabelField() and before offsetForCapturedLabelField(). Called from the main thread. Beware that this anchor can be overridden with LabelCaptureAdvancedOverlay.setAnchorForCapturedLabelField() method. This method will only be called for new tracked fields that do not have an anchor yet, e.g. an anchor set by a call to LabelCaptureAdvancedOverlay.setAnchorForCapturedLabelField().

offsetForCapturedLabelField(overlay, labelField)

Future<PointWithUnit> offsetForCapturedLabelField(
        LabelCaptureAdvancedOverlay overlay,
        LabelField labelField)

Added in version 7.2.0

Offset to be set to the view corresponding to the given LabelField. The offset is relative to the anchor point of the tracked field. This method will be called after widgetForCapturedLabelField() and anchorForCapturedLabelField(). Called from the main thread. Beware that this offset can be overridden with LabelCaptureAdvancedOverlay.setOffsetForCapturedLabelField() method. This method will only be called for new tracked fields that do not have an offset yet, e.g. an offset set by a call to LabelCaptureAdvancedOverlay.setOffsetForCapturedLabelField().
