Hi, I can help build the Flutter foundation with a clean architecture that keeps onboarding, screen logic, and data access separated for easier testing and safer releases. My focus would be setting up the project structure, Provider state management, email/password signup, phone verification, core wireframe screens, and push notifications that work properly in foreground, background, and terminated states on iOS and Android. Relevant experience includes Flutter app development, authentication flows, state management, UI implementation, and notification integration with device testing across platforms. I also provide signed test builds at each milestone so progress is easy to review. Timeline-wise, I’d start with the app foundation and auth flow, then move to the screens, and finish with notification handling and cross-device validation. One quick question: do you want push notifications implemented with Firebase Cloud Messaging, and should phone verification be SMS-only or include a fallback flow? If you’d like, I can review the requirements in Freelancer chat or a video call and get started right away. Regards, Ghanu & Samir KESHAV INFOTECH

Howdy, The best way to keep a milestone based Flutter project on track is to make every stage produce a clean, testable build rather than waiting until the end to validate everything. I would structure the app from the start so each milestone can be tested properly on real iOS and Android devices. I can build the onboarding flows, wireframe driven screens, background push notifications, and required iOS/Android builds while keeping presentation, business logic, and data layers clearly separated. I’d also organize Provider carefully and abstract network and storage services so they remain easy to test and replace later. I will keep the repository clean with consistent Dart conventions, linting, and focused commits, making each milestone easier to review and maintain. I can show you similar Flutter projects in chat, including work involving Provider and push notifications. Once you share the wireframes and feature list, I can break everything into practical milestones and confirm the build requirements for each stage.

★★★ FLUTTER SPECIALIST ★★★ Hi, To ensure a successful project, I recommend considering the potential challenges with cross-platform compatibility, especially with push notifications and state management. Testing on both iOS and Android devices is crucial to identify any platform-specific issues early on. For implementation, I will utilize Flutter's capabilities to create a single codebase that adheres to Material and Cupertino design guidelines. I will implement user onboarding with secure email and phone verification, ensuring a smooth user experience. The Provider package will be used for state management, and I will evaluate its structure to optimize performance and maintainability. I will provide signed builds for each milestone, allowing for real-time testing on physical devices. My focus will be on writing clean, modular Dart code with a clear separation of concerns, ensuring that the codebase remains maintainable and scalable. To get started, I will need access to the wireframes and feature list, as well as any specific design assets you may have. Thanks!

@Eliteinno

Hi, are you looking to ensure push notifications trigger reliable deep links on physical devices without polluting the UI layer with state logic? Wrapping the push notification handler outside the widget tree and pairing it with a centralized router ensures payloads execute correctly even when the app is completely closed. Structuring the codebase with abstract repositories for network and local storage calls allows seamless mocking during unit tests while keeping Provider models strictly focused on business logic. Generating production-signed TestFlight builds and APKs at each milestone keeps physical device validation straightforward and catches platform-specific iOS entitlements early before main branch merges. Is phone verification running through Firebase Authentication, or is there an existing custom backend API handling the SMS gateway and push tokens? Should incoming background notifications open specific screens directly via deep linking, or simply launch the main application view? Would you prefer to review the proposed folder structure and service wrapper interfaces on Git first, or begin directly with the authentication milestone?

@DeveloperStation

Hi, I've shipped mobile apps with phone verification and background push before. On a recovery support app we handled phone based flows and Firebase notifications so alerts arrived even when the app was closed. Marijuana Anonymous: play/app store build, meeting finder and notification handling in a cross-platform app. One thing on your Provider note. For phone auth plus push I'd split providers by concern, an auth notifier and a notifications notifier, so the verification state and token refresh don't tangle. I'll write the data calls behind interfaces from day one so they mock cleanly for tests, which matches your swap-later requirement. Question: for phone verification, do you have an SMS provider picked (Firebase Auth, Twilio), or should I propose one? Adil

@zainalitariq245

Hello there You need a clean Flutter app where each milestone produces a real installable build for testing. The main challenges are reliable phone and email authentication plus push notifications that work in background and closed states. I will use Flutter with Provider and a layered structure separating UI business logic and data access. I will follow your wireframes closely while keeping the Dart code modular testable and easy to extend. Network and storage services will remain replaceable for future testing. Each milestone will include signed Android and iOS builds with the corresponding Git branch ready for review and merge. Would you like Firebase to handle phone authentication and push notifications or do you already have a backend in place? Portfolio: https://www.freelancer.pk/u/zainalitariq245 Best Regards Zain Ali.

Hi, The signup and notification features in a Flutter app require careful integration between frontend UI flows and backend services to ensure a smooth user experience and reliable message delivery. The part I would validate early is the orchestration between the mobile client and backend notification infrastructure to handle registration tokens and delivery acknowledgments. While my recent experience focuses on backend AI and data pipelines, I have designed modular systems that separate ingestion, processing, and delivery layers, which is applicable to managing signup workflows and notification orchestration. I typically design systems by separating frontend client state management from backend API services to allow independent scaling and testing. My approach would include validating token lifecycle management and notification reliability early to avoid user experience issues. Ensuring notification delivery reliability through retries, fallback routing, and monitoring will reduce user complaints and improve app stability. I can help define the first technical milestone by outlining the signup flow architecture and notification delivery pipeline. Clifton

@denisSolution

Hi, I'm Denis, a full-stack developer with hands-on experience building cross-platform mobile apps in Flutter. I've worked on projects involving user authentication, push notifications, and state management with Provider—skills that align perfectly with your needs. I understand you need a production-ready Flutter app with email and phone verification during onboarding, wireframed screens following platform guidelines, reliable push notifications, and signed builds for each milestone to test on real devices. That's a solid approach. My workflow starts with a requirements review to clarify edge cases in the onboarding flow, then I'll set up the project with clear separation between UI, business logic, and data layers. I'll implement authentication first, then build screens milestone by milestone using Provider for state management. Push notifications will use a dedicated service layer so you can swap providers later if needed. Each milestone delivers signed APKs and IPAs ready to install on your devices. One thing worth discussing upfront is how you want to handle token refresh and session persistence across app restarts—getting this right early prevents authentication issues down the road. The main risk I'd watch for is unclear wireframe details around form validation or notification behavior, but we can clarify those in the initial review to keep implementation on track. I can start right away. Let's connect and discuss the details. Thanks, Denis.

@abhishek060

Hi, I went through the requirements, and the important part here is not just converting the wireframes into Flutter screens. With Provider, authentication, push notifications and milestone-by-milestone device testing, I’d keep the UI, state, business logic and data access separated from the start. That way the screens stay simple, API/local-storage code can be mocked or replaced later, and adding another flow doesn’t mean rewriting existing widgets. I’d also handle push notifications as a separate service rather than mixing notification logic into individual screens, including the background/closed-app cases. Since you’ll be testing every milestone on real devices, I’d treat the signed Android/iOS build as part of each milestone—not something left until the end. One thing I’d confirm: do you already have the backend/event source that will trigger push notifications, or should that integration be included as well? If you share the wireframes, I can review the flow and give you a milestone-wise estimate. Regards Abhishek

@Proswift

Hi, You need a Flutter app for iOS and Android from your wireframes: email/password + phone verification, main screens (Material/Cupertino as fits), FCM push (including background/killed), and Provider for state — with signed APK and TestFlight builds every milestone. I build Flutter apps with a clear UI / logic / data split, Provider (or layered ChangeNotifiers when a screen needs it — I’ll outline before coding), and Firebase Auth + FCM for onboarding and alerts. Modular Dart, lint-clean, swap-friendly network/storage wrappers. $15/hr — milestone branches on GitHub, merge only after your device install check passes. Happy to point to recent Flutter + Provider/push work once we start. Best regards
