First of all, credit to Sankal Bansal on his New Zealand Version of the similar control with the same provider.
I was recently working on a specific task to implement a new Address Autocomplete/Validation solution. So, the selected validation/provider was AddressFinder. This API provider provides quite extensive information that the typical Australian addresses need (GNAF ID, DPID, Geolocation, and some more IDs provided as the metadata).
Traditionally, we create an HTML web resource that interacts with the main page script. But then the roadmap ahead is going towards building PCF controls. So, I decided to give it a go on building this PCF control.
To begin my journey, I was looking at https://pcf.gallery/ and found some good examples of address autocomplete with Azure Maps & Google Maps. I learned the concept from those examples, then I found Sankal’s solution that is almost the same as what I would like to achieve. However, his solution is based on New Zealand’s dataset (metadata and mapping are different) and doesn’t map the full address to a field.
So, I created a specific Australian solution for this PCF. You can find the detail at my github repository: https://github.com/andz88/PCF.AddressFinderAU
The workaround to get the mapping is to follow this post: https://www.magnetismsolutions.com/blog/jaredjohnson/2019/07/04/binding-to-address-fields-in-a-pcf-control, as this is a known issue with the PCF: https://powerusers.microsoft.com/t5/PowerApps-Ideas/Enable-binding-to-OOB-Address-Fields/idi-p/302387
