Firebase Emulator issues with

[DionJChapman]

When using the Emulator that is only HTTP and not HTTPS the cloud_functions will return NOT FOUND Exception.

To fix this you need to use .httpsCallableFromUrl instead of .httpsCallable

Example
HttpsCallable callable = await FirebaseFunctions
.instanceFor(region: 'us-central1')
.httpsCallableFromUrl(
'http://127.0.0.1:5001//us-central1/processUpdateClaims');
final resp = await callable.call(<String, dynamic>{
'uid': user.uid,
'role': 'somerole',
});

if the documentation for this can be updated that would be great.
