BarcodeArView

class BarcodeArView : StatefulWidget

Added in version 7.1.0

Barcode AR comes with a ready-to-use UI that allows highlighting barcodes and displaying additional information over them. The BarcodeArView integrates with any app in just a few lines of code.

BarcodeArView.forMode(dataCaptureContext, barcodeAr)

factory BarcodeArView.forMode(DataCaptureContext dataCaptureContext,
        BarcodeAr barcodeAr)

Added in version 7.1.0

Creates a new BarcodeArView with the provided mode, viewSettings and cameraSettings.

BarcodeArView.forModeWithViewSettingsAndCameraSettings(dataCaptureContext, barcodeAr, viewSettings, cameraSettings)

factory BarcodeArView.forModeWithViewSettingsAndCameraSettings(
        DataCaptureContext dataCaptureContext,
        BarcodeAr barcodeAr,
        BarcodeArViewSettings viewSettings,
        CameraSettings cameraSettings)

Added in version 7.1.0

        BarcodeAr barcodeAr,
        BarcodeArViewSettings viewSettings)

Added in version 7.1.0

Creates a new BarcodeArView with the provided mode, viewSettings and default camera settings from BarcodeAr.createRecommendedCameraSettings(). This is equivalent of calling forMode() with null cameraSettings.

start()

Future<void> start()

Added in version 7.1.0

Starts the scanning process.

stop()

Future<void> stop()

On Android the highlights and annotations that are already shown are kept, and they are still there when scanning starts again. On iOS they are removed, and they are supplied again by the providers after the next start. Resetting or disposing the view removes them.

pause()

Future<void> pause()

Pauses the scanning process.

The highlights and annotations that are already shown are kept, so they stay tappable while the view is paused and when scanning starts again. Resetting or disposing the view removes them.
