Describe your issue. If applicable, add screenshots to help explain your problem.

In my app I use google_mlkit_barcode_scanning on android if I use camera 0.10.6 its work and scanning but If I use camera 0.11.0 Or higher Its not scanning!

Steps to reproduce.

use google_mlkit_barcode_scanning on android with camera 0.11.0 Or higher it will not scanning barcode.

What is the expected result?

Its should Scanning barcode with all version of camera

Did you try our example app?

Yes

Is it reproducible in the example app?

Yes

Reproducible in which OS?

int idY = 0;

final uvWidth = width ~/ 2;
final uvHeight = height ~/ 2;
// Copy Y & UV channel.
// NV21 format is expected to have YYYYVU packaging.
// The U/V planes are guaranteed to have the same row stride and pixel stride.
// getRowStride analogue??
final uvRowStride = uPlane.bytesPerRow;
// getPixelStride analogue
final uvPixelStride = uPlane.bytesPerPixel ?? 0;
final yRowStride = yPlane.bytesPerRow;
final yPixelStride = yPlane.bytesPerPixel ?? 0;

for (int y = 0; y < height; ++y) {
  final uvOffset = y * uvRowStride;
  final yOffset = y * yRowStride;

  for (int x = 0; x < width; ++x) {
    nv21[idY++] = yBuffer[yOffset + x * yPixelStride];

    if (y < uvHeight && x < uvWidth) {
      final bufferIndex = uvOffset + (x * uvPixelStride);
      //V channel
      nv21[idUV++] = vBuffer[bufferIndex];
      //V channel
      nv21[idUV++] = uBuffer[bufferIndex];
    }
  }
}
return Uint8List.fromList(nv21);

}
}

use this enxtension for retrive bytes @salar-dev

I also encountered the same problem, if with [camera 0.10.6] it will return to normal.
