@burhanuday Hi, first of all, my compliments on the very clear blog post. I have one small remark though, the @use-expo/font package is deprecated, as the useFonts hook is part of the core expo-font package for quite a while now.
To avoid confusion for Expo users that come across your blog, would it be possible to either update the snippets to use expo-font (it's a drop-in replacement), or add a note at the beginning of the article? Thank you!

Hi, thanks for this was a big help today. However, I got an error using Apploading and destructured it one step further by creating a SetFont.js component and importing it into the root component. I have tested and the fonts are available throughout the app.

const SetFonts = () => {
const [isLoaded] = useFonts({
'AlfaSlabOne': require('../../assets/fonts/AlfaSlabOne-Regular.ttf'),
'OpenSans': require('../../assets/fonts/Open_Sans/OpenSans-Regular.ttf'),
'Calibri': require('../../assets/fonts/calibri/Calibri-Regular.ttf')
})

if (!isLoaded) {
return AppLoading
} else {
return null
}
}

Hi, if this is the exact code you're using, wrap Font is loading... in quotes - "Font is loading...". That might be the problem

Hi, yep I added return AppLoading back instead and it works now

It worked and now I went back to the project and getting an error message I need to use Font.loadAsynch. I have fixed with add the code later but I think need to add the fonts manually to the android project as not working on device.

Hi, i'm really struggling for import fonts in my code... One tutorial say to use "react-native link" and another says to use "Font.useFonts". The one that worked for me is the second but I would like to load all fonts once in the App.tsx and then use them in all other components, how can I do this?
