Implementation of Stockfish Library in our Chess App

Hello,
I'm reaching out to you because we have developed a chess application and currently require some assistance with the integration of the Stockfish chess engine. We have the UI completely set up, but we're facing challenges in implementing the engine to consistently run on 8 distinct difficulty levels. Currently, it initializes at random difficulty levels, which is not what we are aiming for.

Here are the specific requirements:
Integrate the Stockfish library from: https://pub.dev/packages/stockfish
Ensure the chess engine operates consistently with 8 distinct difficulty levels.
Address the issue we are encountering, which is detailed here: https://github.com/official-stockfish/Stockfish/issues/4431
Familiarize with the UCI (Universal Chess Interface) documentation to ensure optimal integration: https://rdrr.io/cran/stockfish/man/fish.html

We believe someone with your skill set and experience could be a perfect fit for this task. Could you please let us know your availability, estimated completion time, and a quote for this project?

Looking forward to a fruitful collaboration.

Regards,
Janusz
