I run a small, fast-moving product team and I’m adding a dedicated Flutter specialist to our daily workflow.

Mine X – City-Based Ad Widget App Interactive, Location-Driven Advertising Platform 1. Project Overview The Mine X City-Based Ad Widget App transforms a user’s home screen into a live, interactive discovery platform. Instead of showing static ads, this widget allows users to swipe left or right to browse different cities, and swipe up or down to explore ads, events, or promotions within that city. Every 15 seconds, new content appears automatically—giving Mine X brands and partners continuous exposure while users enjoy real-time local discovery. 2. Objectives • Build a Flutter-based mobile app with an Android home-screen widget. • Display rotating, clickable ads managed through a simple backend. • Enable multi-city browsing and category exploration via gest...
I’m ready to step up the onboarding flow in my existing Flutter headless storefront for Shopify. The first milestone—and highest priority— is Sign in with Phone Number using OTP, and I’d like you to wire it up with Firebase Authentication. Once that piece is solid, we’ll add Sign in with Google and Sign in with Apple so shoppers can choose whatever feels easiest. Here’s what I need delivered: • Phone-number login via Firebase OTP, fully tested on iOS and Android • Google and Apple sign-in hooks that reuse the same customer record logic • Seamless hand-off to Shopify Storefront API so authenticated users land in their existing customer account (or a new one if none exists) • Clean, well-commented Dart code plus a short integrat...
“Contact Us to Continue. There may be an issue with your account…” We have already trying with multiple Apple IDs (Gmail + domain email) and on multiple iOS devices, but the same error appears every time. This confirms the issue is related to Apple Sign-In configuration, developer account setup, or the iOS authentication flow, not the user’s account.
I need a Flutter developer to put together a lightweight inventory-management mobile app that runs only on Android. This first version can stay simple—just the essentials so I can log items, edit quantities, and view a quick stock list on one screen. Core requirements • Built with Flutter and Dart, targeting the latest stable SDK • Add, edit, and delete inventory items (name, quantity, optional note) • Local persistence—SQLite or Hive is fine; no server work for now • A clean, minimal Material 3 UI that feels native on modern Android devices • Source code, a signed APK, and brief setup instructions when you hand over the project Nice-to-have (if it fits easily): search or filter by item name and a simple low-stock indicator. Keep the code wel...
The task is to build a production-ready mobile application with Flutter that ships seamlessly to both iOS and Android from a single code-base. I will provide the product concept, brand assets, and any required APIs; your role is to turn those inputs into clean, maintainable Dart code, integrate the UI with the back-end services, and prepare release builds for the App Store and Google Play. Key success criteria: • A smooth, native-feeling experience on current iOS and Android devices. • Source code managed in Git with clear commit history and documentation. • Build artifacts ready for TestFlight and internal testing on Android, followed by store-ready release builds. Please plan to collaborate on state management choices, automated testing, and deployment workflow...
I already have the full front-end UI of a ride-hailing app built in FlutterFlow and a starter template you can extend. Now I need the core logic finished so the product feels as seamless as Uber. Here’s the scope in plain language: • Backend integration – I’m fine with either Firebase or Supabase, so choose whichever lets you move fastest and keep the architecture clean. • Driver-to-rider matching – real-time assignment logic plus status updates visible to both sides. • Maps API work – show each party’s live location on the map and keep the feed responsive as they move. • Stripe payments – basic card capture and charge flow are partly wired; you’ll polish and prove a successful transaction from request to receipt. ...
I have an app idea but no visuals or code yet. I’m looking for one person who can handle the entire early-stage cycle—creating a clean Figma prototype and then turning it into a small Flutter MVP. Here’s what I need: • Shape the concept with me, then produce a basic user flow, low-fidelity wireframes, and a polished Figma design (around five key screens: splash, login/registration, main dashboard, feature page, and settings). • Build the same screens in Flutter using clean, well-commented Dart code that follows Material Design guidelines. Android is the immediate target; iOS build is a bonus if it doesn’t add major overhead. • Include a simple state-management approach (Provider or Riverpod) and placeholder data so I can see navigation and intera...
Need Flutter Developer for SmartLedger (Offline + Google Drive Backup Accounting App) Description: I need a Tally-style accounting app for Android, made in Flutter (Dart). The app should work offline using a local SQLite database and also support Google Drive backup/restore. I already have a requirement PDF that explains all features clearly.
I’m ready to build a from-scratch food-ordering app in Flutter and would like to code it live with you over Zoom, screen-sharing the entire session so we can keep the vibe flowing and decisions instant. Core stack • Flutter (no pre-made UI kits; every widget handcrafted, though taking visual inspiration is fine) • Firebase for auth, data, and storage • Razorpay as the payment gateway Key screens and flows 1. OTP-based login—this will be the only authentication method. 2. Restaurant list—pulls data from Firebase and presents every restaurant in a clean, modern layout that matches my brand colors and existing logo. 3. Menu detail—tapping a restaurant reveals all its food items, each with image, price, and add-to-cart action. 4. Cart &...
I want to release a cross-platform mobile application built in Flutter that combines wellness guidance with astrology insights. The overall aim is to give users a calming, easy-to-navigate space where they can check daily inspiration, track personal growth, and explore astrological content—all from a single, attractive interface on both iOS and Android. I’ll rely on you to help refine the exact feature set, but the build should feel modern, load quickly, and be architected for future expansion (for example, adding premium content or community areas later). Clean, maintainable Dart code, adaptive UI, and clear documentation are essential. Deliverables • Flutter source code with well-commented logic and modular structure • Pixel-perfect UI/UX that passes my review o...
We’re looking for an experienced Flutter Developer to build a modern, scalable, and visually rich frontend for our modular platform, a dynamic two-choice voting and question app with real-time interaction, content creation, and monetization tools. You’ll work closely with our backend (Go) and DevOps (AWS + Cloudflare) teams to implement a clean, maintainable frontend that performs seamlessly across iOS, Android, Web, Desktop, and TV platforms. Responsibilities: - Develop and maintain the Flutter frontend following Clean Architecture (Presentation, Domain, Data layers). - Implement key features across multiple modules. - Integrate APIs built in Go/Fiber via REST (and WebSocket where needed). - Ensure smooth real-time synchronization of votes, comments, and results. - Apply re...
I have a production-ready fitness app built with Flutter that needs three key upgrades alongside a round of bug fixes. First, I want Stripe fully integrated so users can pay inside the app with a smooth, native experience—handling tokenization, secure storage, and webhook callbacks for purchase confirmation. Next comes subscription management. The app should offer Monthly and Yearly plans that automatically renew, can be paused or cancelled from the settings screen, and sync correctly with Stripe’s billing portal so invoices and failed-payment retries are handled without manual work. Finally, I want to roll out a points-based loyalty program. Each completed workout and every in-app purchase should award configurable points, which users can later redeem for free classes, m...
I recently updated my Flutter code and now my project refuses to build in Android Studio. The compiler stops without any major error just some warnings and hints, along with a few related references that weren’t an issue before the upgrade. Everything ran smoothly prior to the update, so I’m certain the problem is tied to version changes rather than logic in my code. What I need is simple: open the project with the latest stable Flutter, trace the compile-time issues, and get it running again on the Android emulator. If we have to tweak the pubspec, replace deprecated APIs, or migrate to newer widget syntax, that’s fine—I just want a clean, warning-free build that launches without crashing. I’ll share my current flutter doctor output the moment we start. Onc...
I am building a cross-platform productivity solution that will be used daily by professionals I already work with offline. My role covers market research, client acquisition, and day-to-day operations in the field; I now need a partner who can own the entire technical stack. The core of the product is a productivity tool that must feel identical on the web, iOS, and Android. I see the back-end running on PHP with Laravel for rapid development and clean API design, while a single Dart / Flutter codebase delivers the two mobile apps and a responsive web front-end. You would lead architecture decisions, write production-ready code, set up CI/CD, and iterate quickly alongside real-world feedback I gather from users. Initial milestones I have in mind: • Build and deploy an MVP featuring ...
I have a Flutter mobile app that embeds Google Maps to display a location panel. The moment that specific panel loads, the app crashes and closes. No other screens are affected, so I’m certain the issue sits within the Google Maps implementation or its interaction with the surrounding widget tree. What I need: • Pinpoint the root cause of the crash (logs currently show only an abrupt shutdown). • Deliver a clean, tested fix that stops the crash on both Android and iOS builds. • Briefly document the change so I can apply the same pattern elsewhere in the codebase. Helpful context: – Flutter 3.x, Dart 2.18+ – google_maps_flutter plugin (latest stable) – Crash occurs the instant the location panel renders; no user interaction needed. When ...
I have an existing Flutter code-base that I want running on my Windows machine. I’m uncertain whether the Flutter SDK, Android Studio, or Visual Studio Code are already configured, so the first step will be verifying (and, if necessary, installing) every component a standard Flutter workflow needs. Here’s what I expect from you: • Connect with me in a quick screen-share session (AnyDesk, TeamViewer, or similar) and run flutter doctor to audit my current setup. • Install or update the Flutter SDK, Android Studio, required Android SDKs, device emulators, and the Flutter/Dart extensions in VS Code if they’re missing. • Clone or pull the project into an appropriate workspace, resolve any dependency or Gradle issues, and ensure it compiles and launches su...
I need an EMI Calculator built with Flutter that targets Android only for now. The app should let a user enter three fields—loan amount, annual interest rate, and loan tenure—then tap a single button to see the exact monthly EMI along with total interest and total repayment. Immediately after the calculation, the app must also generate a full amortization schedule that lists principal, interest, and remaining balance for every installment. Another key feature is persistence: any calculation can be saved to a local store and viewed later from a simple history screen. I’m fine with SQLite, Hive, or SharedPreferences so long as the data survives an app restart and loads quickly. I will share rough wire-frames and the formula sheet I currently use. What I expect back is cle...
