Context for this issue: https://github.com/invertase/dart_firebase_admin/issues/6
It appears that if a user tries to create a client with clientViaApplicationDefaultCredentials, yet have neither the environment nor gcloud/application_default_credentials.json setup, then google_apis_auth fallbacks to reaching out to metadata.google.internal.
The problem is that if that endpoint is unavailable (which is likely the case if the user made a mistake and did want to login using the other options), then we end-up with a "Failed host lookup: 'metadata.google.internal'" error.
This is likely confusing, and a better error message could make it more intuitive to understand what the issue is.
