Flutter Expert to Merge 2 Apps into 1 (InDriver Style) - $22 + 5-Star Rating & Great Review

I am looking for a freelance developer for a straightforward integration task. I already have the full source code for two transport apps (Rider and Driver). The goal is to merge both into a single application, where the user can switch roles via an internal toggle button, exactly like the InDriver app.

Objectives:

Single App: Integrate both existing Flutter projects into a single build/binary.

Role Toggle: Implement an easy-access button or side menu to switch between "Passenger" and "Driver" modes without logging out.

Language & Localization: Set the entire app to Portuguese (Brazil) - pt-BR.

Maps: Configure the Google Maps API to be centered in Brazil by default. (I already have the API Keys ready).

Business Logic: No changes needed to the backend or core logic; just UI/UX integration and code organization.

Technical Requirements:

Strong experience with Flutter & Dart.

Familiarity with Google Maps SDK.

Clean code and folder structure to ensure a stable, unified project.

Budget & Reward:

Fixed Price: $22.00 USD.

Bonus: I will provide a 5-Star Rating and a great positive review on your profile for a job well done.

Future Work: Potential for long-term maintenance and future projects.
