`Error: Element type is invalid` with react-native-maps v1.0.0

After updating to v1.0.0 of react-native maps I got the following error:

 ERROR  Error: Element type is invalid: expected a string (for built-in components) or a class/function (for composite components) but got: undefined. You likely forgot to export your component from the file it's defined in, or you might have mixed up default and named imports.

Check the render method of `MapViewDirections`.

Seems to be a change with the exports of react-native-maps. Here’s a patch that fixes the error for me:
