I need a production-ready cab-hailing application built with Flutter so it runs smoothly on both iOS and Android from a single codebase. The mobile client will consume a fresh set of ASP.NET Core Web APIs that you create and host; the APIs should follow REST best practices, be fully documented, and stay modular so extra features can slip in later without rewrites. For this first release the essentials are straightforward: riders must be able to request a ride, see available drivers, and once the trip ends, leave a rating and short review for the driver. No real-time map tracking or payment gateway is required right now, but keep the data models and endpoints flexible so we can introduce those options down the road. Login should be quick and frictionless—users enter their phone number, receive a one-time password by SMS, and they’re in. I’m not interested in email/password or social logins at this stage. Because I’ll be handing the project to an internal team after launch, clean code and clear comments matter as much as the feature set. Stable state management (Provider, Riverpod, or Bloc—whichever you prefer) and a well-structured ASP.NET Core solution are key. Deliverables • Flutter source code with build instructions for iOS & Android • ASP.NET Core Web API project with README and brief Swagger docs • SQL Server (or PostgreSQL) script for initial schema and seed data • Simple driver and rider test accounts so I can demo the flow • Short hand-off session or video walkthrough covering project setup and deployment Acceptance criteria: builds successfully on both mobile platforms, OTP authentication functions end-to-end, rides can be requested and completed, rating/review posts to the database, and API endpoints return the expected JSON. If the scope is clear and you’re confident with Flutter and ASP.NET Core, let’s get started.

Dear Client, I read "Flutter Cab Booking App Build" carefully and understand you want a single Flutter codebase that runs smoothly on both Android and iOS. My hands-on experience with Mobile App Development, iPhone, Android, ASP.NET, Flutter, API Development aligns directly with what you need. I've shipped Flutter apps from scratch to store launch — clean architecture, smooth animations, native-feeling UI and solid API integrations — that stay easy to maintain as features grow. A few quick questions to get us started: 1. Do you need Android, iOS, or both from day one? 2. Are UI designs ready, or should I design the screens as well? 3. Is there an existing backend/API, or should I build that too? Thanks & Regards, Deepak

You need a production-ready Flutter cab app backed by a modular ASP.NET Core API, with phone OTP login, ride requests, driver availability, and post-trip ratings working cleanly on both iOS and Android. I’ve built cross-platform mobile systems with Flutter and production APIs, and my backend experience includes structured REST services and database-driven applications. I’d build the Flutter client with Riverpod or Bloc, keep the ASP.NET Core API modular, document endpoints through Swagger, and use PostgreSQL or SQL Server with clean migrations and seed data. The ride model will be designed so maps, live tracking, and payments can be added later without restructuring the core flow. I’ll also cover OTP verification, rider/driver test accounts, API error handling, validation, and the handoff documentation your internal team will need. For this scope, I’d estimate 3–4 weeks for a solid first release. Do you already have an SMS/OTP provider selected, or should I integrate one?

Hi there, The Flutter side of this is a strong match — single codebase for iOS and Android, OTP-only auth, clean state management, code structured for a smooth handoff to your internal team afterward. To be upfront: my team's backend experience is primarily Node.js, not ASP.NET Core/C# specifically. I don't want to claim a stack I haven't actually shipped in. Two ways I'd suggest handling that: Option A: I bring in a dedicated ASP.NET Core developer for the API layer while I own the Flutter client and API contract design — you still get a proper C#/.NET backend your internal team can maintain. Option B: If you're open to it, I deliver the same REST architecture in Node.js instead — same modularity, same Swagger-equivalent docs, same SQL schema approach, just a different runtime for your team to inherit. Technical approach either way: - Flutter (Provider/Riverpod) for the rider app - Phone OTP via SMS, no email/social login - Modular REST endpoints for ride request, driver list, rating/review - Flexible data models ready for maps/payments later Deliverables match your list exactly — source code, API docs, DB script, test accounts, and a walkthrough session. Let me know which option fits your internal team's stack better. Best, Chirag

You need one clean Flutter app + one modular ASP.NET Core API—not a prototype that becomes difficult for your team to maintain. I’d structure the first release around the exact flow you described: phone OTP → rider requests a ride → available drivers are shown → trip completion → driver rating/review. I’ll keep the architecture ready for later GPS tracking and payments without adding unnecessary complexity now. My approach: Flutter with Riverpod/Bloc and clean, reusable feature structure ASP.NET Core REST API with modular services, DTOs, validation and Swagger PostgreSQL or SQL Server with clear relationships and seed/demo accounts SMS OTP authentication with proper expiry/verification handling Ride lifecycle designed so tracking/payment can be added later Clear README, build/deployment instructions and hand-off walkthrough I’ll also test the complete flow on both Android and iOS before handover rather than just delivering source code. One question: do you already have an SMS provider in mind for OTP (Twilio, Firebase, or another provider)?

Hi, I will build your Flutter cab-hailing app for iOS and Android, backed by a modular ASP.NET Core Web API with Swagger docs, phone plus OTP login, ride requests, driver listing, and post-trip ratings. I can start today. I will use Riverpod for state management and keep the data models flexible so map tracking and payments can slip in later without rewrites. Questions: 1) SQL Server or PostgreSQL for the schema? 2) Which SMS provider should I wire in for OTP? Looking forward to discussing further. Regards, Shayan.

Hi, I’ve reviewed the requirements and the scope is clear. I’m experienced with Flutter for iOS/Android and ASP.NET Core Web APIs, including OTP authentication, REST APIs, database integration, and clean state-managed architecture. One point I’d like to confirm before estimating accurately: should the driver side also be included in this release for accepting/completing ride requests, or will driver actions be handled separately? I look forward to the opportunity to collaborate and bring your project to life.

OTP login without rate limiting can let bots flood the SMS endpoint. I'll set up a short-lived token store in ASP.NET Core and use a throttled SMS provider to keep the flow smooth. The Flutter side will use Riverpod for state, keeping the UI clean while the API follows REST conventions ready for map and payment hooks. A common mistake is tying the ride request directly to UI state, which makes it hard to add driver location later. By keeping request model separate, the app will handle ride creation and completion, and API will return JSON for rating endpoint. You’ll get clear comments and a hand-off video that walks the internal team through setup and deployment.

Straight answer on scope: a production-ready two-sided cab app plus a hosted ASP.NET Core API is not a 12,500 build. Your average bid sitting above your own ceiling says the same thing. Phase one, INR 12,500, 3 days: the ASP.NET Core API and schema (riders, drivers, rides, ratings) with Swagger, SQL script and seed data, OTP auth working end to end, plus the Flutter shell with that login live on both platforms. You can log in on a real phone at the end of it. Phase two is ride request, driver list, trip completion and rating, priced once phase one is in your hands. One thing to start before anyone writes code, or it will stall you: SMS OTP in India needs DLT registration. Your entity, your sender header and your OTP template all have to be registered before messages deliver. Unregistered templates get dropped silently. It takes days and only you can do it, because it is tied to your business identity. Cheap insurance: even with no map tracking now, store driver lat/lng and a timestamp on the ride record from day one. Then adding tracking later is a UI job, not a schema migration. Do you already have a DLT-registered sender, or do we start that clock now?
