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

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?

The default font that React Native uses is "System font", which refers to the font used by the operating system on which the app is running.
On iOS, the system font is San Francisco, and on Android, it is Roboto.

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

Can I use Three.js in React Native for Desktop?

As I understand, React Three Fiber(R3F) supports React Native, but not sure if it works in the React Native for Desktop App. (R3F).
They uses expo-gl library, and the offical document of expo says that it supports android, ios, and web.
Does this mean that I cannot use R3F in React Native for Desktop (Windows, macOS)?
I've tried to initiate the React Native for Desktop app and tried to install three, R3F, and, expo-gl and run, but it didn't work.

Google Font with Styled Components and Expo

I'm working on a managed workflow Expo React Native app and am using Google Fonts (Nunito Sans specifically). I imported the font from #expo-google-fonts/nunito-sans and am loading it using the useFonts hook.
When using the font in styled components like font-family: "Nunito Sans", I get the error that:
fontFamily "Nunito Sans" is not a system font and has not been loaded through Font.loadAsync.
- If you intended to use a system font, make sure you typed the name correctly and that it is supported by your device operating system.
- If this is a custom font, be sure to load it with Font.loadAsync.
Is there any way I can still load Nunito Sans using useFonts?

Changing fontFamily in native base library of react native does not work

I am using native-base library in react native. I have done following steps to change font but it does not work:
I pasted myfont.ttf in this directory:
node_modules/native-base/Fonts
I went to the following directory:
node_modules/native-base/src/theme/variables/...
and changed all font families into myFont.ttf in all three files (commonColor.js, material.js and platform.js)
Please help me in this issue.
You have to first eject NativeBase's theme, you can do that by
following the docs
here.
Then, add font to Android and iOS respectively, this
article
shows a good guide on how to do that.
Lastly, you can update the theme with your custom font on ./native-base-theme/variables/<theme-you-use>.js, also describe on the same docs above
