Flutter iOS and Android Apple HealthKit GoogleFit Fitbit

Need to build a beta Flutter application to allow users to connect to AppleHealth on the iOS version, and GoogleFit on the Android version. Users also can connect to Fitbit devices via a backend call. Once connected to a device we need to show the past 7 days’ activities, and steps besides user weight changes. All backend work will be provided for you.

More details:
– Basically, I wanna integrate My Application with Apple Healthkit, GoogleFit, and Fitbit.
– Basically, the user will have one page to select a device to integrate.
– For Fitbit, you will need to open a web browser, call my API, and the user should log in on Fitbit, subscribe, and get the token back. then save the token into DB via API.
– For Apple/Google There is a flutter Library you can use.
– In the end, I need to sync user Activities from the integrated device
When the user calls the sync icon.

Definition of done:
– Working application in iOS: Android.
– 1 Home page.
– 1 Device last page with add device page.

The goal for this beta is to build our trust, check code quality and stability and publish a working version on iOS/Google stores. You should have an up-to-date MAC OS compatible with iOS 16.
