I use react-native-elements, and they make it easy to make an actual button appear "raised", or shadowed. I want to duplicate this look for TouchableOpacity.
Here's an example of the "raised buttons" with react-native-elements.

It is subtle, but noticeably makes a nice impact.
How would you go about mimicking this effect with TouchableOpacity?
And yes, I've gone through the docs. If I missed anything, please point it out... but I don't think anything is there to accomplish this. Thanks.
