What are the best android libraries written in kotlin to clone, look at and learn from? Currently trying to my my own library but I am kinda stuck on finalizing it and improving it

Sunflower is supposed to be the latest and greatest with Android, Google isn't always the best at keeping documentation up to date though so I wouldn't treat it as the holy grail. https://github.com/android/sunflower DisneyMotions is a neat library if you are interested in animations. https://github.com/skydoves/DisneyMotions Kotlin wise, I would still start with Kotlin Koans though, it provides some good fundamentals that you can build off of.
