progressbutton | A custom progress indicator with a tiny footprint | Android library

I want to call a function from my StatefulWidget when a button in my StatelessWidget is pressed. In the following code you can see what I'm trying to do. I'm not really sure how it works, so maybe you can help me.

StatelessWidget - Button should call function from StatefulWidget

I have trying to get current location with Location.when i call the function in button it will ask for enable location but after enable location it take some time to fetch location data instead of that after i press the button a circular indicator should show with in button.This is is what i did.the problem is the circular indicator doesn't show

Submit button

I made a reusable circular progress bar. I applied repeatForever animation to keep it rotating but it only works when used directly with a @State or @Published variable and doesn't work when it is embedded in another view.
