Using fallbackSource property and unable to provide styles for it

Please give a demo code showing how can I provide styles on fallbackSource image .
Thanks for proving such good library for multiple network images with caching.
```
<CachedImage
    style={{ width: width / 2.35, height: 180, }}
   source={{
   uri: "https://vesyl.in" + prod.image_url
   }}
   fallbackSource={require('../img/pro.png')}
></CachedImage>
```
