Flutter developer knowledge with live tracking app using Hypertrack(Read description carefully)

I am looking for a Flutter developer with experience integrating APIs, specifically Hypertrack. The primary goal of this project is to track the user's location using live tracking. The expected timeline for completing this project is 1-2 weeks. The ideal candidate will have experience with both Flutter development and integrating Hypertrack APIs.
The app is already already build using google api. Need to change the app's UI and implement the Hypertack instead of google apis.The backend is in firebase.
Deadline is important.
