DocumentAutoCaptureWidget class final

Document Auto Capture UI component (widget).

The widget with instructions for obtaining quality document images suitable for further processing.

Widget configuration

In order to configure the behaviour of DocumentAutoCaptureWidget, use DocumentAutoCaptureWidgetConfiguration and pass in to DocumentAutoCaptureWidget.new. This is a required parameter.

Control the widget and consume outputs

As soon as the widget is created, the onCreated callback is called with the DocumentAutoCaptureWidgetController parameter. Use the controller to control the Document Auto Capture process.

To start the Document Auto Capture process call the DocumentAutoCaptureWidgetController.start method. You can start the process any time.

When the Document Auto Capture process finishes successfully, the result will be returned via the onFinished callback.

In case you want to force the capture event, call the DocumentAutoCaptureWidgetController.requestCapture method. The most recent image will be returned via the onFinished callback asynchronously.

Call DocumentAutoCaptureWidgetController.start method again in case you need to start over the Document Auto Capture process (e.g. you want to capture both sides of the document, one after another).

You can also call DocumentAutoCaptureWidgetController.start method to stop and start over ongoing process as well.

In case you want to stop the Document Auto Capture process prematurely, call the DocumentAutoCaptureWidgetController.stop method.

UI Customization

IDV Flutter SDK is wrapper around the native Android and iOS SDKs. If you want to customize the appearance of the widget on the Android platform, refer to the Android UI customization for detailed instructions. If you want to customize the appearance of the widget on the iOS platform use iosStyle.
