Hi, there. I have carefully reviewed the requirements for Flutter App Revamp: Logo, Menu & Payment. Based on your goals, you are looking for a mobile experience that is not just functional, but seamless and responsive for your users. My team and I specialize in mobile app engineering with a focus on high-performance architecture. We have a proven track record of helping businesses in Saudi Arabia build mobile solutions that scale effectively across both iOS and Android. Whether we are leveraging PHP, Android, App Design, iOS Development, Mobile App Development for a native build or a cross-platform solution, our focus is on ensuring the interface is intuitive and the backend data handling is secure. We treat every app we build as a long-term asset. We avoid common pitfalls in mobile development such as memory leaks or poor UI responsiveness, ensuring your users have a smooth experience from their very first interaction. To help me provide a precise timeline for your development, I have one quick question: Are you aiming to launch on both platforms simultaneously, or are you prioritizing one (iOS or Android) for your initial market validation? Knowing this helps me determine the most efficient architectural path for your project. I am available for a discovery call to discuss your mobile roadmap whenever you are ready. Best regards Kausar and the Team

Hi there, I can see this revamp is less about “small edits” and more about making the app feel complete and trustworthy again. Updating the logo/icon, adding a new section with fresh screens, and wiring a payment gateway across iOS and Android is the kind of Flutter work I handle carefully with clean architecture and attention to edge cases. I’ve worked on Flutter app updates, UI changes, and payment integrations, including maintaining source code so the app stays stable after release. I’ll update the branding assets, build the new menu flow, connect the payment flow properly, and test the full path on both platforms so nothing breaks in real use. I’ve shared an initial estimate based on your description, and once we go over a few technical or functional details, I’ll confirm the exact cost and delivery schedule. Could you share which payment gateway you want to use, and whether the new menu section needs any login or backend data? Also, do you already have the updated logo/icon sizes prepared for App Store and Play Store assets? Looking forward to your reply so we can finalize the exact plan. Best regards, Asad

Hi, this is a bounded Flutter modification project, but the real engineering risk is not the logo or screens, it is making the payment flow reliable across iOS and Android without introducing state or navigation regressions. I've worked on several live-product enhancement efforts where the job was to enter an existing codebase, map the current structure, and add features cleanly with test coverage and a stable handoff. In Flutter work, that usually means reviewing navigation, state boundaries, API touchpoints, and release-specific behavior before changing UI. The closest examples are Custom Feature Development & Integration and AI-Driven Marketing Suite Development -- 2. Both involved extending an existing product, integrating external services, and delivering maintainable updates rather than isolated prototypes. I usually structure work here in layers: app shell updates, new menu and screen flow, payment transaction handling, then cross-platform validation. The main tradeoff is whether to fit the payment path into the current app patterns or isolate it enough to reduce regression risk. I build changes for long-term production use, with attention to edge cases like interrupted checkout, duplicate callbacks, and inconsistent client state after payment completion. If useful, I can start by reviewing the current Flutter source and sketching the safest integration path for the new section and payment flow. Thanks, Hercules

Dear Hiring Manager, Thank you for sharing the project details. I understand you need updates to an existing Flutter application, including branding changes, a new menu module with custom screens, and secure payment gateway integration while maintaining compatibility across iOS and Android. Implementation Approach: • Replace the existing logo, app icon, and branding assets throughout the application. • Develop the new menu section and required screens following the existing app architecture. • Integrate and configure the payment gateway with proper validation and transaction handling. • Perform cross-platform testing, resolve issues, and deliver clean, updated source code. A few questions: • Which payment gateway will be integrated (Stripe, Razorpay, PayPal, etc.)? • Is the new menu functionality already defined with wireframes or requirements? • What Flutter version is the current application using? I can review the source code and provide an accurate timeline after assessment. Can we discuss details? Best regards, Jitendra

Hi, You already own the Flutter source, so the logo and icon swap plus a new menu section is quick - the real care goes into the payment gateway, wiring it cleanly and testing the full flow on both iOS and Android before it touches live money. I've shipped Flutter apps with payment integration and push notifications, and I keep code clean so your next dev isn't lost. Once you share the source, the new logo, and the gateway docs, I'll map the menu screens and confirm the gateway's SDK on day one, then build, test on real iOS and Android devices, and hand back the updated source. I can finish in 3 days and send you progress updates as I go. Which payment gateway are you using, and is it card-only or do you need wallets too? Regards, Nurullah Al Masum

Your Flutter revamp project is right in my wheelhouse. I will refresh the app with a new logo, update the app icon, and create a clean, accessible menu section that fits your existing architecture. I will implement the new screens in the added section, wire in a payment gateway, and ensure a seamless flow on both iOS and Android with thorough testing and fixes. The code will stay clean and maintainable, with clear progress updates as we move through milestones. With experience in Mobile App Development and iOS Development, I will make the gateway integration robust and scalable for future needs. Here are a few quick alignment questions to tailor the work: 1) How should the new menu integrate with current navigation and state management? 2) What payment gateway options and transaction flows do you need (one-time vs. recurring, saved cards, refunds)? 3) Which payment gateway(s) and regional compliance requirements should we prioritize to ensure a smooth iOS and Android deployment? If you share sample screens or a design brief for the logo and menu, I can lock visuals faster. Timeline: a compact sprint of about 7-12 days; I will deliver the updated source code with documentation. Cost details can be discussed after confirming exact requirements.

Hi, I have 6+ years of experience in Flutter development, with hands-on work modifying and extending existing production apps. I can take on all the tasks outlined: Replace app logo and app icon (iOS + Android, including all required icon sizes/assets) Add a new menu section/page with the required screens, built to match your existing app's structure and code style Integrate a payment gateway (I've worked with Stripe, including Payment Sheet, saved payment methods, and Connect/escrow flows — happy to adapt to whichever gateway you choose) Full testing on both iOS and Android after changes Bug fixing related to the new implementation before final delivery Deliver clean, updated source code Since I'll be working inside your existing codebase, I'll first review the current architecture (state management, folder structure, existing patterns) to make sure new code stays consistent and maintainable rather than bolted on. Estimated timeline:6 days depending on payment gateway complexity and number of screens in the new section — happy to confirm once I see the codebase and final requirements. and price is 150$
