/**

* 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:
