Integrate User Live location on Map (Flutter)

Hi,

We would like to add a function to an app that we are looking to buy. It currently has a map with people nearby, but we would like it show the live location of the users. As users move, it moves on the map.

Additionally, we would like the main profile to have sub profiles, for example owner as the main profile and then the ability for them to add pets & info.

We would to add these functions to a dating app, link below.
