Flutter Cab Fare App Enhancements

I need an experienced Flutter developer to enhance my already built cab fare prediction application. Key requirements include:
- Integrating Google Maps as a location tracking service, allowing users to share their ride's location with a contact.
- Implementing API integrations with Google Maps API, Uber API, and Ola API for fare pricing.
- Developing a redirection mechanism that opens the respective cab service's app directly, rather than keeping the user within our application.

Ideal candidates should have:
- Proven expertise in Flutter development.
- Prior experience with Google Maps integration.
- Familiarity with Uber and Ola APIs.
- Understanding of app redirection mechanisms.
