Methods

launch

This function initiates the barcode scanning process by launching a new page (Activity on Android/ViewController on iOS) that displays the camera stream and any other associated UI elements that help with the scanning process. The launch method accepts an optional BarcodeScannerConfig configuration object that allows the developer to customize the scanner’s behaviour and UI.

Future<BarcodeScanResult> launch(BarcodeScannerConfig config)

Returns

A Future<BarcodeScanResult> that resolves with the BarcodeScanResult when the scanner is closed.

Remarks

Please note that the launch method needs a valid Barcode Reader license in order to operate. You can request a 30-day trial license via the Trial License portal.
