upgrade code from get to null safety ( whole project)

Hello, I am seeking a freelancer to upgrade my code from get to null safety. The code is written in flutter, and I am flexible with the timeline. The existing code is fully documented. I am looking for someone who can deliver an excellent job with efficiency and attention to detail. The project should be completed in accordance with the latest conventions and standards in the programming language. If you think you're the person for the job, I look forward to hearing from you. Thank you for your time.
