TextRecognizer class

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

A text recognizer is created via textRecognizer() in FirebaseVision:

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

final TextRecognizer textRecognizer =
    FirebaseVision.instance.textRecognizer();

final List<VisionText> recognizedText =
    await textRecognizer.processImage(image);
