Api Intigration Documentation for flutter Framework

My Question or Issue

Requested Sir/Ma'am, 
How do I put spotify songs in my own application? You guys don't have any documentation of the application.
So one of my requests is that you guys should also provide a documentation in Flutter framework so that developers can get a new benefit. And you will benefit tool̥
Can you show me the full documentation and an example of all the functionality of your play/pause.

Thank you 
for Flutter Developer
