For Now Live OCR is only Available on IOS, I was hoping if you could add Live OCR for Android.

imglib.Image? _convertJpeg(CameraImage image) {
   return imglib.Image.fromBytes(
       image.width, image.height, image.planes[0].bytes,
       format: imglib.Format.rgb, channels: imglib.Channels.rgb);
}

Is there any reason not to use this? The logic is difficult, so I don't have the confidence to maintain it...

I agree with you !

Right now I am working on converting image from Bytes at Dart end Just like you showed above. Once Image is generated then I will send the Image to Android / IOS to get OCR result.

Worried about the performance though. I'll share the updated Code in few hours.

Also any suggestions on how to maintain the session and avoid reinitializing tesseract Instance again and again for each frame / image ?
