React native get default style props?

How can I get the default style props from inside my React Native app or with a debugging tool? I tried with React Devtools, but they only show the props that I set, not the default ones. But I am interested in the default values. How can I watch them? I do not want to depend on the documentation and want to really check it in my running app. I am using functional components.
