What is the best way to capture the progress of file upload and download using Retrofit with kotlin
I have two different codes 
1. I created a request extended class and performing update and getting callback in interface
2. I created extension function with request body and collecting it in flow by calculating the file size and content delivered 
But in both cases I have to write a lot and I need one plug and play solution, by above i created a function and calling it from many places 
Any recommendations?

The problem I am facing is that I am using it in coroutines and it is not like other api calls that returns exact type of response data class
Instead I need to collect the progress and update the view
Is there any better approach?

This is :not-kotlin: for the most part, but I wrote about this problem and the possible solutions here <https://dev.to/zsmb13/adventures-in-tracking-upload-progress-with-okhttp-and-retrofit-1gff>

I know it has some parts totally not kotlin 
But I am not getting help from other sources so asked here

Thank you for the link
I will go through it

I just checked the link 
My code is very much similar
