Hey there @marudy,
I love this package and the work that has been put into it.
I have a suggestion about moving from the Dimensions API provided by react-native to the useWindowDimensions hook newly provided by react native, as this automatically updates width and height values when screen size changes. I believe this eliminates the need for an event listener to detect when screen dimensions have changed(landscape/portrait). If you concur with this, I can raise a PR to this effect.
