Have fun! Note that it is GPL-licensed. Also, note that the "main" branch is for a very old Dart/Flutter version (but it does correspond to what's in the App Store and on the site today).

I've been working on a separate branch, which finally builds (there were 1100+ errors), but I'm still working through iOS/macOS build things for it before merging it to main. (I've sadly had to abandon the Android build, because Google Play was a comparative pain, and FluidSynth upstream kept breaking the Android build I set up for them. But I'm reviving the project for iOS, macOS, and web at least.)

Here's the branch: https://github.com/JonLatane/BeatFlutter/tree/update-to-late...
