Summary

As the title explains, I see an error when building and running this minimal expo example:

Hi @drewboardman! What version of expo-splash-screen do you have installed locally? E.g. run node --print "require('expo-splash-screen/package.json').version" in the project root.

It seems that you are using a very old version of expo-splash-screen, that still tries to load the close-to-3-years-deprecated unimodules.
