A few days ago I had this urge of making my own music player, since I have a Subsonic capable server (ampache) to host and serve music. I've been using DSub, which has a lot of features that I don't use, but works very very well. Alas it isn't "up to date" in terms of design.
So I made my own, heavily inspired by Android 13, Material 3 enabled, has dynamic colors / system theme fallback (a small thing that goes a long way, I didn't want to make an half baked customisation screen, since Android already has one why not use it?)
This was my very first Flutter and Dart experience, and I must say it was very enjoyable! The docs are awesome, there are a lot of plugins to choose from, hot reloading... I know now that I needed that feature, it's a must have to iterate quickly! I might have reduce the amount of time I slept the past few days but it was very well worth it.
Here is demo video https://imgur.com/a/SwOxcij (it has changed a bit since then, mostly on boarders/padding, by a few pixels at most but still relevant ; more up to date pictures on the readme of the github repo)!
