New requirements as of June 11, 2018

To use the Map or Street View component, you must enable billing for Google Cloud Platform and use a valid Google Maps Platform API key.

New pricing for Google Maps Platform goes into effect on July 16, 2018. When you enable billing, you get $200 free usage every month. For many users, the $200 monthly credit is enough to support their needs.

See the Google Maps Platform Guide for Existing Users for details on these changes.
