My actual developing took place on a Windows machine. Then I bought a Mac and figured I'd develop on it.

However, once the application launched on the phone, the GoogleMap wouldn't display, even though the rest of my app was functioning normally. Then I found this link => https://github.com/react-community/react-native-maps/issues/69, went to my console.developers.google.com/ and opened my Google Maps key that I had issue with.
