This workflow uses the current device location, querying it for address properties such as street name and postcode. The resulting properties are put together to form an address which is shown to the user. The address is then URL encoded and appended to a URL string to create a Google Maps link to the address.
Please note that there is a Get Addresses from Input action that can retrieve the address in a single action. This however is an example showing how you can iterate over and combine properties such as those from a location.
