Crash on Android: Attempt to invoke virtual method 'int java.lang.Double.intValue()' on a null object reference

[Twinbird24]

I'm running into this on an Android emulator (Motorola API level 25 with Android 7.1.1) and getting the following error whenever I navigate to a screen/component that uses this library. I'm using version 3.0.0-alpha.1 because this version allows me to add a gradient border to my elements—but this apparently only works on iOS.
