Does the problem always occur in the same file? can you provide the file?

[fahad-whizpool]

where i call the FlutterTess right after the line below. _resultString = await FlutterTesseractOcr.extractText( imagePath, args: { "preserve_interword_spaces": "1", }, );

[khjde1207]

Can you provide a sample? I just tried updating kotlin_version and dependencies.

[fahad-whizpool]

Here is the complete method where that line of code is called.. Future loadWithIdOrCreateNewWithImage( int id, String imagePath) async { if (id > 0) { try { _warrantyCard = await DBManager.instance.loadWarrantyCardById(id); _oldWarrantyCard.copyFrom(_warrantyCard); Future.delayed(Duration(milliseconds: 500), () => _warrantyCardController.add(_warrantyCard)); } catch (e) { Future.delayed(Duration(milliseconds: 500), () => _warrantyCardController.addError(e)); } } else if (imagePath != null && imagePath.isNotEmpty) { //var result = await TessPlugin.getStringFromImage(imagePath); String? _resultString;

  try {
    // //old code
    // _resultString = await SimpleOcrPlugin.performOCR(imagePath);
    debugPrint("beofre ocr flutterr...............");
    //*************************new code********************
    _resultString = await FlutterTesseractOcr.extractText(
      imagePath,
      args: {
        "preserve_interword_spaces": "1",
      },
    );
  } catch (e) {
    debugPrint("FlutterTesseractOcrError=$e");
    _warrantyCard.setDescription =
        "error in recognizing the image / photo => ${e.toString()}";
  }
  final _decodedResult = _resultString;
  if (_resultString != null || _resultString!.isNotEmpty) {
    try {
      print('Print result before parse****');
      // print(jsonDecode(_resultString)['text']);
      final phoneString = _parsePhoneNoIfAny(_resultString);
      //debugPrint("phoneNo=**********>$phoneString");
      _resultString = _parseResultDate(_resultString);
    } catch (e) {
      debugPrint("Error Occured=$e");
      rethrow;
    }
    _resultString = _resultString.substring(
      24,
    );

    print(_resultString);
    _warrantyCard.setDescription = _resultString;

    _warrantyCard.setCardNum = _parseCardNumber(_decodedResult!);
    final c = _parseCardNumber(_decodedResult);

    debugPrint("cardNo=======>$c");
  } else {
    _warrantyCard.setDescription = "No Result";
  }

  _warrantyCard.setImagePathWithExtension = imagePath;
  Future.delayed(Duration(milliseconds: 500),
      () => _warrantyCardController.add(_warrantyCard));
} else {
  throw 'Both id and imagePath were illegal.';
}

return _warrantyCard;

}

Is imagePath a local path? flutter_file_dialog allows you to save that image elsewhere. can you give me this image? https://pub.dev/packages/flutter_file_dialog

[jipika]

imagePath 是本地路径吗？ flutter_file_dialog 允许您将图像保存在其他位置。 您提供我这张图片吗？ https://pub.dev/packages/flutter_file_dialog
