Project Title: Flutter Sprint: Payment Gateway, Incentive UI, & Penalty Logic (3 Apps) Project Overview We have an existing food delivery ecosystem built with Flutter (Frontend) and Laravel (Backend). We need an experienced Flutter developer to integrate specific modules and fix minor logic issues across three apps: Customer, Restaurant, and Delivery Man. The backend APIs are 100% ready; this is primarily an integration and UI mapping task. Detailed Scope of Work 1. Payment & Marketing SDKs Razorpay Native Integration: Enable UPI Intent flow (direct launch of GPay, PhonePe, Paytm) for Wallet Top-ups. Meta (Facebook) SDK: Integrate App Events for install and purchase tracking. Custom Notifications: Replace default system sounds with provided .mp3 (Android) and .caf (iOS) files. 2. UI & User Experience Enhancements On/Off Availability Toggle: Move the "Online/Offline" switch from the side menu to a prominent position in the Home Screen Header for both Restaurant and Delivery apps. Incentive Dashboard: Create a new UI screen in the Delivery app to display: 7-day earning grid (Orders, Hours, Payout). Active/Inactive bonus slot cards based on API data. 3. Penalty & Restriction Logic (Strict Requirement) Order Rejection Penalty: If the API returns a blocked status, the Home Screen must show a Countdown Timer and disable the "Go Online" toggle. Zone Penalty: Implement a warning popup and countdown lock if the driver is restricted due to "Out of Zone" or "Excessive Toggling" status. 4. Bug Fixes Call Masking: Debug the "Handshake Error" in the existing Flutter code to ensure the Click-to-Call feature works seamlessly. Technical Requirements Tech Stack: Flutter 3.x, Dart, Laravel (API consumption). Environment: Must have a Mac (Xcode) for iOS builds and sound file integration. Ownership: This is a "Functional Delivery" project. You are responsible for minor UI alignments and logic connections to ensure the features are 100% production-ready.

Hello, I hope you are doing well. I can definitely help integrate these Flutter modules and UI updates across your customer, restaurant, and delivery apps. My approach would be to first update the payment and SDK integrations (Razorpay UPI intent, Meta App Events, and custom notification sounds), then implement the UI changes like the availability toggle and incentive dashboard, and finally connect the penalty logic and bug fixes to the existing Laravel APIs to ensure everything works smoothly in production. I have experience working with Flutter apps, payment integrations, and API-based systems, so I’m confident I can deliver these features reliably. Two quick questions: 1) Are the API endpoints for the incentive dashboard and penalty statuses already documented and ready for integration? 2) Is the project currently using state management like Provider, Riverpod, or Bloc, or should I follow the existing architecture in the codebase?

Hi, I can help integrate Razorpay UPI Intent, Meta SDK events, custom notification sounds, and the incentive dashboard UI across your three Flutter apps while connecting everything smoothly with your existing Laravel APIs.

I know the frustration of juggling multiple Flutter apps—Customer, Restaurant, and Delivery—while making sure every payment flow, incentive screen, and penalty logic works seamlessly. That’s exactly what I specialize in: turning complex Flutter integrations into smooth, production-ready experiences. Previously, I’ve successfully delivered Flutter integrations for multi-app ecosystems in food delivery and fintech, including payment flows, dashboards, and conditional logic, always ensuring zero post-launch surprises. To reduce risk, I provide open communication, versioned commits, and thorough testing on both iOS and Android devices—so you get fully functional apps ready for release. I can start mapping the SDKs and penalty logic immediately and have a working build for your review within the first few days. Let’s get these apps fully synced and production-ready.

Hi, Integrating a payment gateway and enhancing UI/UX for your Flutter apps is a critical step for improving user experience and operational efficiency. Focusing on the Razorpay integration and the required UI adjustments will help streamline transactions and ensure users have a seamless experience across the Customer, Restaurant, and Delivery apps. Getting the UI elements right, especially the visibility of the online/offline toggle and the incentive dashboard, will significantly impact user engagement and satisfaction. In previous projects, I worked on integrating payment systems and optimizing mobile app interfaces. This included implementing similar SDKs and enhancing user flows, resulting in a noticeable increase in transaction completion rates and user retention. My background in both Flutter and Laravel means I can quickly address any backend API consumption issues while ensuring the frontend is intuitive and responsive. To kick off this project, I would first assess the current app structure and the existing Flutter code to identify any potential challenges in the integration process. After that, I would prioritize the payment gateway integration, followed by the UI enhancements and logic adjustments, ensuring each phase is validated through testing to reduce risks of deployment errors. What specific timeline are you aiming for to have these integrations completed? Are there any existing design guidelines for the UI enhancements, or are you open to suggestions?
