Flutter App Update – Firebase Sync, RevenueCat Fix, UX Improvements -- 2

@WebTechDesignBG

Woah Hello, It sounds like you're looking for someone to help refine and update your existing Flutter app, with a focus on syncing data with Firestore, fixing email verification issues, and improving the overall user experience. With 7+ years of experience in Flutter development, I have a solid background in Firebase integration, including Auth and Firestore, as well as RevenueCat functionalities. To tackle your project, I would start by ensuring that local storage syncs seamlessly with Firestore, implementing offline support while preventing duplicates. I would also address the email verification issues by configuring your custom domain and optimizing email delivery. Additionally, I can enhance the RevenueCat subscription logic and streamline the onboarding process to make navigation more intuitive for users. Looking forward to contributing to your app's success! Best regards, Ivan Mandinski

Hello, Your app already has the core pieces in place, so this sounds more like a focused refinement project than a rebuild—which is exactly the kind of work I enjoy. I have strong experience with Flutter, Firebase, and RevenueCat, including offline-first sync, Firestore security rules, subscription logic, and improving onboarding and UX without disrupting existing functionality. I can help make sure local storage syncs cleanly with Firestore across devices, prevent duplicate shift records with unique IDs, tighten up email verification using your custom domain, and fix subscription states so trial, monthly, annual, and expired users are all handled correctly. I’ve also worked on optimizing data-heavy flows and polishing navigation so the app feels smoother and easier to use. Based on the scope, I’d estimate around 3–5 days for a clean review, implementation, testing, and final refinements. Looking forward for your positive response in the chatbox. Best Regards, Arbaz M

I can refine your existing Flutter app by implementing reliable offline-first Firestore sync (with duplicate-safe shift handling), fixing Firebase email deliverability with proper domain authentication (SPF/DKIM/DMARC), and stabilizing RevenueCat subscription logic including trial, restore, and status UI states. I’ll also improve onboarding UX, navigation clarity, and make small performance tweaks to scraping and calendar display while keeping your current architecture intact. Best Regards, Muhammad

@waqaswebmaster

Hi There This kind of update usually breaks at sync logic—not UI—especially when offline-first data starts conflicting across devices. I’d handle this by implementing a proper sync layer (local → Firestore with unique IDs + timestamps), conflict-safe writes, and rule-based security so duplicates and overwrite issues don’t occur. On top of that, I’d fix Firebase email deliverability (SPF/DKIM/DMARC + custom domain), clean up RevenueCat state handling (trial/active/expired sync with UI), and streamline onboarding + navigation so actions feel immediate and clear. I’ve worked on Flutter apps with Firebase + subscriptions where stability and data consistency were critical, not just feature completion. Are you currently using any state management (Provider, Riverpod, Bloc), or should I standardize the app structure while implementing these fixes? best regards Waqas A.

I have strong experience with Flutter, Firebase, and subscription systems, ensuring clean and reliable updates. I can complete this efficiently within a few days. Best regards, Shakila Naz

@hassans5

This is a well-scoped “refinement + stabilization” task, and since your app already has most systems in place (Flutter + Firebase + RevenueCat), the focus is really on fixing sync reliability, subscription logic, and email deliverability without disrupting existing flows. I can handle the offline-first Firestore sync properly (with conflict-safe IDs and auto-resume syncing), tighten Firebase Auth email setup with SPF/DKIM/DMARC so verification emails actually reach inboxes, and debug RevenueCat so trial/subscription states reflect correctly in the UI. I’d also improve onboarding UX and navigation clarity while keeping changes lightweight and consistent with your current structure. For scraping and calendar display, I’d only optimize where safe without introducing instability. Given the scope and existing implementation, this is realistically a short, focused enhancement cycle with clean verification at each step. Looking forward for your positive response in the chatbox.

@engruhulajom

Dear Client, I’m an experienced Flutter developer with 10+ years of expertise building and optimizing production mobile apps using Firebase, RevenueCat, and offline-first architectures. I understand your app is already built and you need focused improvements: offline Firestore sync with deduplication, email verification fixes with proper DNS/authentication setup, RevenueCat subscription logic correction, and UX refinements. I’ve handled similar Flutter projects involving offline sync (Hive/SharedPreferences + Firestore reconciliation), subscription state management, and Firebase Auth email deliverability improvements (SPF, DKIM, DMARC, custom domains). My approach is incremental and safe: fix sync architecture first, stabilize auth/email flow, then refine RevenueCat logic and UX improvements without disrupting existing features. Looking forward to hearing from you. Best regards, Md Ruhul Ajom

@mickeysz

Hello, I’m a Flutter developer with solid experience in Firebase (Auth + Firestore), RevenueCat, and offline-first architectures. I’ve worked on apps with local storage sync, subscription flows, and cross-device data consistency, so your scope fits well with what I’ve handled before. I focus on fixing issues cleanly without breaking existing functionality, especially in already-live apps. For your case, I’d implement a proper sync layer (local → Firestore with conflict handling and unique IDs), fix email delivery via domain authentication (SPF/DKIM/DMARC), and audit RevenueCat to ensure subscription states and restore flows are accurate. UX tweaks and scraping optimizations can be handled alongside without overcomplicating the codebase. Quick questions: are you using Hive/SQLite for local storage, and is your scraping logic running on-device or via a backend? Also, are Firestore rules already partially configured? I can complete these updates within a few days and keep everything stable and maintainable. Best regards
