React Native common errors tracking

My project was working fine 2 months ago, today I come in and build. It’s through a bunch of error messages on my face. And it’s took me 2 hours to google and fix it. So I make this one to record all issues I got while working with React Native. The solutions already on the internet, but to save time I will write it down here just in case.
