error demo BarcodeReaderD12 DELPHI 12

[edugdr]

Hello,
It gives an error when I try to compile the example BarcodeReaderD12:

[dcc32 Error] FMX.Filter.pas(575): E2003 Undeclared identifier: 'SFilterAlreadyExists'
[dcc32 Fatal Error] FMX.Controls.pas(24): F2063 Could not compile used unit 'FMX.Filter.pas'

I do not have those files included in Kastri; they are part of the Delphi source. It seems you may have older versions of those files in the compiler search path.

Hello.
I'm testing BarcodeReaderD12, and with the help of AI I've managed to compile and run it on my phone (I've already managed to get an app running using ZXing). However, with BarcodeReaderD12 it opens the camera and displays the image, but does not capture the barcode. According to the AI, a "play-services-mlkit-barcode-scanning" library or an Android.JNI.MLKit file would be missing. I've been looking for such references to download, but I really can't find them and I'm not so sure that the AI ​​is correct. The truth is that I was only able to compile the demo and make it work in Delphi 12 and 13 with the help of the AI, but I couldn't get it to read the code. I will appreciate any help
Thanks in advance

In future, please report issues to the issues page

However, with BarcodeReaderD12 it opens the camera and displays the image, but does not capture the barcode

Can you attach an image of the barcode you are attempting to scan?

According to the AI, a "play-services-mlkit-barcode-scanning" library or an Android.JNI.MLKit file would be missing

The app needs neither of these, so I suggest using an AI that is capable of answering correctly.

The truth is that I was only able to compile the demo and make it work in Delphi 12 and 13 with the help of the AI

What did the AI say that is different from the instructions?

First of all, thanks for responding.
Second, I apologize, as a new user I am not familiar with the site's policies.

As for the application, I think the code is not relevant, since I have dealt with various types of codes, in different sizes, both on labels and on commercial products.

If the supposed library is not necessary, as you say, it allows me to understand that the error lies elsewhere. I am going to restart the project from the beginning and stick as closely as possible to the instructions.

I will comment on success or future questions.
Thanks, again.
