Flutter Flow Foreman App GPS Sharing: Proof of concept

We are looking for a skilled freelancer who can develop good code with modules, comments and can teach us to maintain it.

To start we want to see how we can work together and we thought about this proof of concept:

You build a flutter flow App (iOS/Android) from scratch:
- Integration with a blank Google Sheet where you can enter your Name and Adress
- API connection to GET this Name and Adress from Google sheet and display it in the App
- GPS location sharing while using the App
- GPS location sharing must work while App is in the background (permissions!)
- API POST to Google sheet to send GPS coordinates
- Update GPS coordinates every 5 minutes until I hit 'stop sharing' button on the App


Project is completed if you can deliver this above App with above functionality and we have tested it. We expect this does not take a lot of time, as the right developer knows how to use libraries, features, pre-built modules. So please write me your best hour estimate on chat.

If communication, code and delivery speed is good we will continue working.
