CW/Morse Code Trainer Inspired by G4FON

Here's a little side project I made with a lot of help from Claude. I'm trying to learn CW/Morse Code and I really like the trainer G4FON Koch Trainer Version 10 (https://www.g4fon.net/) As far as I know it only runs on Windows and I want to be able to practice anytime. Decided on Flutter because I've always been interested. This is just a thing I threw together but wanted to post in case anyone was looking for something similar. The training method and docs are all heavily inspired by G4FON. It's my first public project so hit me up with any feedback on Github. I've only tested on Windows and Android. Not sure how it'll work on other platforms. Happy to fix bugs if I have time. Thanks!
