Google Places is the API for searching and getting details about literal places available on Google Maps.
Like listing shops around some coordinates, or searching addresses with autocompletion, etc. No actual maps involved, only metadata about places.
Google Maps has an iOS SDK and a Android SDK. No Multiplatform SDK.
Unless someone has done it before, you might need to implement your own Kotlin Multiplatform wrapper around these in order to share the logic.
Some
expect/actual
magic to fill the gap.
