I need a skilled Flutter developer to turn my concept for a cross-platform productivity app into a polished, store-ready release. The core of the build is an intuitive task-management workflow where users can create, edit, prioritise and complete tasks. Secure user authentication is mandatory—email/password is essential, and I’m open to social sign-ins if it fits naturally into your architecture. You’ll design the UI in Flutter, wire it to a clean state-management solution and connect it to either a Firebase or REST back-end (I have both options prepared). Smooth performance on both iOS and Android, thoughtful error handling and tidy, well-commented code are all part of the brief. Deliverables • Full Flutter source code in a private Git repo • Auth flow fully implemented and tested • Task-management screens and logic complete, pixel-perfect to Figma files I’ll supply • Release-ready builds (APK & IPA) plus deployment guidance • Basic README covering build steps, package versions and any environment variables I’ll test against a short acceptance checklist: a new user can sign up, log in, add a task, mark it complete, and see that state persist after relaunch. If you’ve shipped similar productivity or task apps before, that context will be a plus—feel free to reference it when you respond.

Hi there, I see this as a cross-platform app where users onboard via secure auth, then enter a core loop of creating, managing, and completing tasks. The key is ensuring that any state change-like marking a task complete-is immediately persisted to the backend and accurately reflected on subsequent app launches, creating a seamless user experience. Technical approach: Flutter with BLoC for clean state management. Firebase is a great fit for auth (email/social) and real-time data sync with Firestore. I'll implement a repository pattern to keep the app backend-agnostic, allowing a clean connection to either Firebase or your REST API. The UI will be a pixel-perfect translation of your Figma files. Core modules: An authentication module for user session management. A task management module for all CRUD operations and state changes. A data sync layer to handle backend communication and reliable persistence. Relevant systems: We've built task-oriented Flutter apps like OurCap (an employee self-service portal) and have designed systems like ORDO, a dedicated task and order management platform, which aligns directly with your concept. I would begin by implementing the auth flow first, followed by the task UI with local state. Finally, I'll connect it to your chosen backend, test the end-to-end acceptance criteria, and prepare the store-ready builds. Regards, Rohit

Hi there, I will build your productivity app in Flutter — auth flow with email/password and social sign-ins, task-management screens pixel-perfect to your Figma files, and release-ready APK and IPA builds with deployment guidance. For state management, I will use Riverpod with a clear separation between UI and business logic. This makes the task prioritization and completion states predictable and testable, and it pairs well with Firebase listeners so task state persists instantly without manual refresh after relaunch — directly covering your acceptance checklist. Questions: 1) Do you prefer Firebase (Firestore + Auth) or the REST back-end for this build — or should I evaluate both and recommend? 2) Will the Figma files include dark mode variants, or is a single theme sufficient for the initial release? Looking forward to discussing further. Best regards, Kamran

Hi I have strong experience building production-ready Flutter apps with Firebase, REST APIs, secure authentication, state management, responsive UI, Git workflows, and Android/iOS release preparation. The main technical challenge here is making the task-management flow feel simple for users while keeping authentication, persistence, error handling, and cross-platform performance reliable under the hood. I can solve this by implementing a clean Flutter architecture with structured state management, reusable UI components, secure auth handling, and persistent task data connected to your Firebase or REST backend. For the app screens, I will follow your Figma files closely and build polished flows for sign-up, login, task creation, editing, prioritising, completion, and saved task history. For the backend side, I can wire email/password authentication, optional social login, task CRUD APIs, local loading states, validation, and clear error messages. I will also provide tidy, well-commented source code, APK/IPA builds, environment setup notes, package versions, and deployment guidance. My focus is to deliver a smooth, store-ready productivity app that passes your acceptance checklist and is easy to maintain after hand-off. Thanks, Hercules

Hi there, I understand you need a polished Flutter productivity app for iOS and Android with secure email/password authentication, optional social login, Figma-based UI, task creation/editing/prioritization/completion, persistent state, clean state management, and Firebase or REST backend integration. I have strong experience building Flutter apps with authentication flows, task-management logic, Firebase/REST APIs, Riverpod/Bloc state management, persistent storage, error handling, responsive UI implementation, release builds, and store-ready handoff documentation. I would implement the app from your Figma files, connect auth and task persistence, test the full signup/login/task lifecycle, prepare APK and IPA builds, and deliver clean source code with README, package versions, environment setup, and deployment guidance. Q1: Which backend should be used first: Firebase or your REST API? Q2: Do tasks need due dates, reminders, categories, or recurring logic in this version? Q3: Are Apple/Google sign-ins required for launch or optional after email/password? Best regards, Stratos

Hi there, I’m a Flutter developer with a track record turning concepts into polished cross‑platform apps. I’ll build an intuitive task-management flow: create, edit, prioritize, complete, with persistent state across relaunch. Auth will start with email/password, with a clean path to social sign-ins if you want them later. I’ll design the UI in Flutter to be pixel‑perfect against your Figma specs and wire it to a clean state-management solution (Riverpod or Bloc, depending on your preference). Back-end options are Firebase or REST as you have prepared; I’ll implement a robust auth layer, secure data access, and offline support where beneficial. Code will be well commented, and the app will ship with careful error handling and performance tuning for both iOS and Android. Deliverables include a private Git repo, fully implemented auth, task screens and logic, APK and IPA with release notes, plus a concise README with build steps and env vars. I’ve shipped productivity apps before and can reference patterns to accelerate delivery. Best, Justin
