TL;DR

Similar questions have been asked before on SO (such as Convert Expo project to Original React Native project, Commands to use after converting from expo to react-native-cli, and Expo to react native init) but none of them explain how to completely remove all Expo modules and dependencies from my project, so that I end up with a pure React Native app (the same as if I had run react-native init... in the first place).

So is it possible to remove all of this extra crap that I never asked for or expected to be installed, with one simple command? MTIA! :-)

Background

Basically I got into this mess by ejecting from a managed Expo project, then customising the android folder a lot before realising that my build/install times were ludicrously slow.

So to fix this, I ran yarn global add depcheck and depcheck, which suggested that I could/should remove all of the following packages (the most seemingly-important ones are marked with an asterisk):

expo-updates*
filtrex
firebase-admin
lodash
mathjs
moment
native-base
nodemailer
react-native-android-location-enabler
react-native-credit-card-input
react-native-document-picker
react-native-fast-image
react-native-geolocation-service
react-native-image-crop-picker
react-native-js-bottom-sheet
react-native-reanimated
react-native-signature-capture
react-native-unimodules*
react-native-web
react-timer-mixin
recyclerlistview
shortid
stripe-client
styled-system
@babel/core
@react-native-community/eslint-config
babel-jest
jest
prettier
react-test-renderer

So I blindly ran yarn remove ... on all of those packages, and now I get a ton of errors on attempting to build. I won't list them here since it's obvious that they're mostly (if not entirely) related to the expo-updates and react-native-unimodules packages marked above.

I'm not explicitly using anything Expo-related in my code, so this should be a cake walk IMO, but is proving to be quite difficult!

So how can I remove this extra cruft properly? Do I need to start fresh with react-native init? MTIA :-)
