Usage

• 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);
