I have a production Flutter application that leans heavily on Firebase, and I need an experienced developer who can jump in quickly to extend and refine it. The current codebase already covers the fundamentals, but several deeper integrations still need attention—secure authentication flows, reliable real-time data handling with Cloud Firestore, and polished push-notification delivery through Cloud Messaging. Your first task will be to review the existing repository, identify weak spots, and propose a plan that keeps the app fast, stable, and easy to maintain. From there, I’ll rely on you to implement the agreed-upon improvements, write clear Dart code, configure any required Cloud Functions, and document what you do so I can keep iterating after release. If you are comfortable diagnosing tricky state-management issues, optimising network calls, and making the most of Firebase’s analytics and messaging services, let’s talk—I’m ready to start as soon as you are.

Hi there, I will audit your Flutter codebase, tighten the auth flows, stabilize your Firestore real-time listeners, and refine push notification delivery via FCM — then document every change for easy handoff. One thing I will prioritize early: structuring Firestore listeners with proper lifecycle management tied to your state solution. Orphaned stream subscriptions are the most common source of memory leaks and phantom reads in production Flutter apps — fixing this first will improve both stability and network efficiency before adding new features. Questions: 1) Which state management approach is the app using — Riverpod, Bloc, Provider, or something else? 2) Are the Cloud Functions already deployed, or will those need to be written fresh? Looking forward to talking through the details. Kamran

Hi there, I have read your project requirement. You need an experienced Flutter developer to review your existing production app, identify gaps, and enhance it with secure authentication flows, reliable real-time data handling using Cloud Firestore, and robust push notifications via Firebase Cloud Messaging. The goal is to improve performance, stability, and maintainability while ensuring clean code, proper state management, and clear documentation for future scalability. We can quickly audit your codebase, propose a structured improvement plan, and implement optimized solutions for authentication, Firestore queries, notification handling, and overall app performance. A few questions: ============= Which state management approach is currently used (Provider, Bloc, Riverpod, etc.)? Are there any specific issues you’re facing right now (crashes, delays, sync problems)? Do you already use Firebase Cloud Functions, or should we design new ones? Do you need improvements in analytics and user tracking as well? Best Regards, Srashtasoft Team
