Is react-native-unimodules a dev dependency or not?

Hi, I was working on upgrading an ExpoKit app and the steps in https://docs.expo.io/versions/latest/expokit/expokit/#upgrading-expokit say to install react-native-unimodules as a dev dependency. However, the README instructions on react-native-unimodules do not: https://github.com/unimodules/react-native-unimodules. The project that I’m working on already had it installed as a regular dependency, but I’m wondering, is it safe to move to be a dev dependency?
