/**
 * In hybrid apps, use `nativeImageSource` to access images that are already
 * available on the native side, for example in Xcode Asset Catalogs or
 * Android's drawable folder.
 *
 * However, keep in mind that React Native Packager does not guarantee that the
 * image exists. If the image is missing you'll get an empty box. When adding
 * new images your app needs to be recompiled.
 *
 * Prefer Static Image Resources system which provides more guarantees,
 * automates measurements and allows adding new images without rebuilding the
 * native app. For more details visit:
 *
 *   https://reactnative.dev/docs/images.html
