Detection on the Image | Flutter Barcode Scanner

The Scanbot SDK efficiently analyzes a still image to identify and extract information from any barcodes present. Once detected, the scanner returns the barcode data in the result.

Processing the image​

With the Scanbot SDK, you can detect barcodes from a still image, such as a JPG from the Photo Library or another source. The image should be provided as a file URI.

Single image barcode detection​

To detect barcodes from a single image:

Uri file = ...;
List<BarcodeFormat> barcodeFormats = ...;
BarcodeAdditionalParameters? additionalParameters = ...;
List<BarcodeDocumentFormat> acceptedDocumentFormats = ...;

var result = ScanbotSdk.detectBarcodesOnImage(
    file,
    barcodeFormats: barcodeFormats,
    additionalParameters: additionalParameters,
    acceptedDocumentFormats: acceptedDocumentFormats
);
  • Result: result.barcodeItems - A list of recognized barcodes as items of BarcodeItem type.

For a complete list of parameters and detailed descriptions, refer to the API documentation.

Multiple images barcode detection​

To detect barcodes from multiple images:

List<Uri> files = ...
List<BarcodeFormat> barcodeFormats = ...
BarcodeAdditionalParameters? additionalParameters = ...
List<BarcodeDocumentFormat> acceptedDocumentFormats = ...

var result = ScanbotSdk.detectBarcodesOnImages(
    files,
    barcodeFormats: barcodeFormats,
    additionalParameters: additionalParameters,
    acceptedDocumentFormats: acceptedDocumentFormats
);
  • Result: result.barcodeItems - A list of recognized barcodes as items of BarcodeItem type.

For a complete list of parameters and detailed descriptions, refer to the API documentation.
