Expo needs to be updated

[matymad]

Hi

I cloned your repo and I atempted to run it but I encountered an error with the babel module. I did only two things in my console:

• yarn (to install all modules, full of warnings)
• expo update

Executing the two prior commands I achieved to run the project (React and React Native).

Thanks a lot. Yo save me a lot of time!!! I would like to submit a PR.

Greetings.
