MapView is broken on web

🐛 Bug Report

Summary of Issue (just a few sentences)

I’ve seen this issue brought up before, but have found no solutions. MapView doesn’t work with Expo running on the web. You can see this just by trying the Snack linked in this documentation:

https://docs.expo.io/versions/latest/sdk/map-view/

The error seems to either be (Snack):

(0 , g.requireNativeComponent) is not a function
  Evaluating react-native-maps.js
  Evaluating App.js
  Loading App.js

Or (locally): TypeError: Object(...) is not a function

Unfortunately I don’t have time to work on this feature right now. It’s a really large project with lot’s of differences between web and native. The developer interface should probably change as well to be more universal and support any arbitrary map service (i.e. Leaflet, Mapbox, Apple maps, Google maps).

The best solution would be to create a new maps package, but that would take a ton of time to create and maintain. I would recommend using the extremely unstable fork for now.

the maker works on system browsers, however, when I try to use markers on mobile browsers, it keeps showing a blank screen without any error whatsoever
