如何在项目中添加类似UI的“解锁环”？

Question

I searched the last hour for any information on how to implement a UI widget that looks similar to the "unlock ring" (see screenshot below).

I did not find any documentation nor libraries that provide such a UI, although I have seen some apps that use the same ring-style (eg the native caller screen) or at least similar styles (eg the alarm clock "Timely").

Are there any libraries or APIs for implementing such a style? Thank you!

It seems that there are two libraries out there that provide such a function:
