OCR Method always returning the exception

KVManpreetam commented 6 years ago

Hi We are using this OCRText widget library for our project, it is running okay, but after scanning the text, it is always throwing the error. even though the text is recognised on screen. code block as follows:

/// /// OCR Method /// Future _read() async { List texts = []; try { texts = await FlutterMobileVision.read( flash: _torchOcr, autoFocus: _autoFocusOcr, multiple: _multipleOcr, showText: _showTextOcr, camera: _cameraOcr, fps: 2.0, ); } on Exception { texts.add(new OcrText('Failed to recognize text.'));

}

if (!mounted) return;
setState(() => _textsOcr = texts);

}

Hi @ KVManpreetam, Could you try this code? And catch the exception?

Future<Null> _read() async {
    List<OcrText> texts = [];
    try {
      texts = await FlutterMobileVision.read(
        flash: _torchOcr,
        autoFocus: _autoFocusOcr,
        multiple: _multipleOcr,
        showText: _showTextOcr,
        camera: _cameraOcr,
        fps: 2.0,
      );
    } catch(e) {
      print('Error: $e');
      texts.add(new OcrText('Failed to recognize text.'));
    }

    if (!mounted) return;

    setState(() => _textsOcr = texts);
  }

While scanning it says UNKNOWN(99) for format and UNKNOWN(99) value format

I have this same issue . I see the text on the screen but no way to access in my terminal or print the text in my terminal . Really need some help. I tried editing the ocrgraphic class but it's read only and won't allow me. I'm a student at a university using this for a project. Please help

I think the problem is because of .so file which cannot be loaded, I have the same problem and I found it inspecting Flutter Console log:
