Cannot find module 'react-native/packager/blacklist'

I see in your example that you use android or ios with gradle. I'm using expo for now but of course I'll migrate to gradle. For now, I copied your transformer.js, rn-cli.config, global.js and did npm3 install node-libs-browser. Here's the error I'm having when I do npm start

***ERROR STARTING PACKAGER***

    throw err;

I did the "eject" and in the 'native' way I can run the app if I rename rn-cli.config.js to something else, but if I name it to what it's supposed to be, then I get:

ERROR ignorePattern is not a function

on Metro, and the app won't launch (red screen with errors)

TLDR:

const blacklist = require('metro/src/blacklist');

If you have react-native >= 0.57 check this:
