@expo/vector-icons/build/vendor/react-native-vector-icons/lib/ensure-native-module-available.js

Built-in support for popular icon fonts and the tooling to create your own Icon components from your font and glyph map. This is a wrapper around react-native-vector-icons to make it compatible with Expo.

import { Platform, NativeModules } from 'react-native';

const NativeIconAPI =
  NativeModules.RNVectorIconsManager || NativeModules.RNVectorIconsModule;

export default function ensureNativeModuleAvailable() {
  if (!NativeIconAPI) {
    if (Platform.OS === 'android') {
      throw new Error(
        'RNVectorIconsModule not available, did you properly integrate the module? Try running `react-native link react-native-vector-icons` and recompiling.'
      );
    }
    throw new Error(
      'RNVectorIconsManager not available, did you add the library to your project and link with libRNVectorIcons.a? Try running `react-native link react-native-vector-icons` and recompiling.'
    );
  }
