Hello,

I have the same issue since the bump to Expo v51. It seems like the problem is only with icons that exist in FontAwesome 5 and not in FontAwesome 6.

I import the package like this: import Icon from '@expo/vector-icons/FontAwesome5';

I tried to import it like this: import Icon from '@expo/vector-icons/FontAwesome';, I have the same issue but with the error: "[icon_name]" is not a valid icon name for family "FontAwesome".

So, some icons have been removed from the free version of FontAwesome 6 that were present in FontAwesome 5.

You can check here : https://icons.expo.fyi/Index

Thank you @doug3d it's working fine now

from react-native-vector-icons.

In my case, UIAppFonts was not set properly. Please make sure of the below format in the Info.plist file.

<key>UIAppFonts</key>
<array>
	<string>FontAwesome.ttf</string>
	<string>FontAwesome6_Brands.ttf</string>
	<string>FontAwesome6_Regular.ttf</string>
	<string>FontAwesome6_Solid.ttf</string>
</array>

same here on react-native 0.74.1, vector icons 10.1.0 though, expo 51 using modules-core, FontAwesome6 Pro

If I kill the app everything is fine but after a while after navigating around in the app I start seeing question marks.

from react-native-vector-icons.

same issue. checked everything. checked linking, info.plist, target config for copy bundle resources. do you have the message `unrecognized font family 'font-name' in XCode?

@tststs I'm developing on Windows, but I don't have any kind of error in console anyway

Same issue here. I am using "react-native-vector-icons": "^10.1.0" and the code is as follows:

import Ionicon from 'react-native-vector-icons/Ionicons';

function getTabBarIcon({
  route,
  focused,
  color,
  size,
}: {
  route: RouteProp<RootStackParamList, keyof RootStackParamList>;
  focused: boolean;
  color: string;
  size: number;
}) {
  let iconName;

  if (route.name === ScreenName.HOME) {
    iconName = focused ? 'home-sharp' : 'home-outlined';
  } else if (route.name === ScreenName.PROFILE) {
    iconName = focused ? 'settings-sharp' : 'settings-outlined';
  }

  return <Ionicon name={iconName} size={size} color={color} />;
}

Each icon is always returned as a a question mark on my end as well.

interlinking with expo issue:

• expo/expo#28693

from react-native-vector-icons.

I found out that caching the .ttf with expo-fonts leads to question marks, after removing this from my code:

function cacheFonts(fonts: any[]) {
  return fonts.map((font) => Font.loadAsync(font));
}

everything works fine.

reverting this PR fixes the issue:

To provide more information for my previous comment, I built my app using the npx react-native@latest init command. Therefore, the expo fix mentioned by @efstathiosntonas is not quite fixing the issue on my end. Here is my package.json:
