DocumentTextRecognizer class

Detector for performing optical character recognition(OCR) on an input image.

In comparison to TextRecognizer, it detects dense document text.

A document text recognizer is created via cloudDocumentTextRecognizer() in FirebaseVision:

final FirebaseVisionImage image =
    FirebaseVisionImage.fromFilePath('path/to/file');

final DocumentTextRecognizer documentTextRecognizer =
    FirebaseVision.instance.cloudDocumentTextRecognizer();

final List<VisionDocumentText> recognizedText =
    await documentTextRecognizer.processImage(image);
