detectAndDecode method

(List<String>, VecMat) detectAndDecode(
  1. InputArray img, [
  2. VecMat? points
])

Both detects and decodes QR code. To simplify the usage, there is a only API: detectAndDecode. https://docs.opencv.org/4.x/d5/d04/classcv_1_1wechat__qrcode_1_1WeChatQRCode.html#a27c167d2d58e5ee4418fd3a9ed5876cc

Implementation

(List<String>, VecMat points) detectAndDecode(InputArray img, [VecMat? points]) {
  points ??= VecMat();
  final strs = VecVecChar();
  cvRun(
    () => ccontrib.cv_wechat_qrcode_WeChatQRCode_detectAndDecode(
      ref,
      img.ref,
      points!.ptr,
      strs.ptr,
      ffi.nullptr,
    ),
  );
  final rval = (strs.asStringList(), points);
  strs.dispose();
  return rval;
}
