Usage

• Set a license key:

  _barcodeReader.setLicense('LICENSE-KEY');
  

• Read barcodes from an image file:

  List<BarcodeResult> results = await _barcodeReader.decodeFile(image-path);
  

• Read barcodes from image file bytes:

  Uint8List bytes = await File(image-path).readAsBytes();
  List<BarcodeResult> results = await _barcodeReader.decodeFileBytes(bytes);
  

• Read barcodes from video stream CameraImage:

  CameraImage availableImage;
  int format = FlutterBarcodeSdk.IF_UNKNOWN;
  
  switch (availableImage.format.group) {
    case ImageFormatGroup.yuv420:
      format = FlutterBarcodeSdk.IF_YUV420;
      break;
    case ImageFormatGroup.bgra8888:
      format = FlutterBarcodeSdk.IF_BRGA8888;
      break;
    default:
      format = FlutterBarcodeSdk.IF_UNKNOWN;
  }
  
  List<BarcodeResult> results = _barcodeReader.decodeImageBuffer(
                availableImage.planes[0].bytes,
                availableImage.width,
                availableImage.height,
                availableImage.planes[0].bytesPerRow,
                format);
  

• Read barcodes from web browser video stream:

  _barcodeReader.decodeVideo(
                              (results) => {updateResults(results)});
  

How to Use the License Key

Mobile

No license required. Instead, you need to get an private organization ID and update the plugin code:

parameters.organizationID = "200001";

By default, the public organization ID 200001 authorize developers to use the SDK for 7 days.

Desktop

Invoke the setLicense() method:

_barcodeReader.setLicense('LICENSE-KEY');

Web

Update the PRODUCT-KEYS :

<script src="https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode/dist/dbr.js" data-productKeys="PRODUCT-KEYS"></script>
