CircularProgressView | Material style circular progress bar for Android | User Interface library

Im making a swiftUI package which can be found here

I am adding a custom view to another view who then has its constraints set programatically. This results in the content of the view being drawn in the wrong place, and I'm not sure why. Here's the code I have and what I tried so far:

I have a LoginActivity in which there are two fragments. Using the navigation library, I switch between these fragments. But now I need to go from the fragment to another Activity. My code doesn't work for some reason, there are no errors in logCat. When I used this code with Activity everything works well. Is it all about a fragment or the navigation library?

My ViewModel

I made a function to make a circular animation. Function takes radius:float as input. I have done this in a ViewController Class and it is working fine for that view controller. But now i want to use this animation on multiple view controllers and don't want to write the same code on every single view controller. So i want to know how can i make this function in a separate file in such a way that i only need to call the function with the radius and it will do the work. Or can you tell me the best practice to do that. Thanks in advance.
