React Native: What is the default font that react native uses?

Question

I'm trying to make a graphic using the same font as the one being used by default in React Native but I don't know what the font is.

Anyone know?

Answer 1

For iOS is San Francisco and to use that you need to pass

fontFamily: 'system font'

Notice that system along will give you an error same if you use 'san francisco'

Answer 2

Pretty sure React-Native just uses the default font family for each platform. So that's San Francisco on IOS and Roboto for Android.
