Dependencies

React Native project. The only React Native API that it relies on is Dimensions
, which has support all the way back to React Native's first release.
Usage
Simply pass a value between 1 and 1000 to vh()
or vw()
to style React Native components.
50% of your device's viewport height: vh(50)
.
33.3% of your device's viewport width: vw(33.3)
.
