Not able to detect text in Arabic language

[bharat8]

Hello,

I am trying to detect text from an image which contains text written in Arabic language. But every time it return empty string.
Here's the minimum reproducible code :-

void checkText() async {
VisionText visionText;
visionImage = GoogleVisionImage.fromFile(File.fromUri(Uri.parse(prov.getImage.path);
TextRecognizer textRecognizer = GoogleVision.instance.textRecognizer();
visionText = await textRecognizer.processImage(visionImage);
print("Detetcted text ---> ${visionText.text}");
}

The link to image i am processing -> https://www.verifave.com/wp-content/uploads/2020/11/Old-Egyptian-Driving-License-.png

Can someone suggest what's wrong here or am I missing some configuration.
