@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 {NativeModules} from "react-native";

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

export default function ensureNativeModuleAvailable() {
  if (!NativeIconAPI) {
    throw new Error(
      'The native RNVectorIcons API is not available, did you properly integrate the module? Please verify your autolinking setup and recompile.'
    );
  }
}
