Add Features to Flutter App

@GameOfWords

Flutter expert with 6+ years in production apps, specializing in auth systems, FCM push notifications, and in-app purchase integrations. I'll seamlessly add Google/Facebook/Apple social login, comprehensive FCM handling, and robust payment gateway integration for subscriptions/one-time purchases while maintaining your existing architecture. All features will respect your current state management, include comprehensive unit/widget tests, and deliver warning-free builds with proper CI/CD integration. Deliverables: Updated Dart code, backend endpoints, setup documentation, and complete test coverage within 2-3 weeks. Which state management solution and payment gateway are you currently using, and do you need user data migration for the auth implementation?

As an experienced developer well-versed in all aspects of mobile app development, I am confident I can successfully execute quality updates and additions to your Flutter app. My expertise in both Android and iOS platforms makes me an ideal fit for integrating user authentication features that support social media logins seamlessly into your existing codebase. Rest assured, the integration will not only respect the current architecture but also comply with best-practice state management for enhanced performance. Additionally, I possess a thorough understanding of Firebase Cloud Messaging and its functioning when it comes to foreground, background, and terminated states. I assure you efficient push notification delivery through Firebase Cloud Messaging as per your requirements. In addition to these essential features, my familiarity with implementing in-app purchases with payment gateways will enable smooth one-off as well as subscription product purchasing experiences inside your app. I understand the importance of maintaining a bug-free build, so comprehensive unit and widget tests will be crafted for the new logic. With my deep-rooted technical knowledge in Flutter, Mobile App Development, API Integration & Web Scraping and hands-on experience deploying robust systems; including ERP, CRM etc., I can guarantee top-notch service delivery throughout this project. Thanks for considering me!

Hello there, I can extend your Flutter app with social logins (Google, Facebook, Apple), push notifications via FCM (all app states), and in-app purchases for both one-off and subscription products. The features will be integrated cleanly into your existing architecture with proper state management and test coverage. I have 11 years of experience in mobile app development and have delivered production Flutter apps with authentication, FCM, and payment integrations across Android and iOS. To proceed: 1. Do you have preferred payment gateways for in-app purchases, or should I set up Google Play Billing and Apple IAP directly? 2. Should notifications also support deep links to specific screens within the app? Best regards.

Hello! User authentication, push notifications, and in-app purchases for Flutter. My Flutter, Firebase, and API expertise ensures seamless, secure, scalable delivery. I have extensive experience with Flutter app development on both iOS and Android, where I’ve successfully integrated social-media logins (Google, Facebook, Apple), push notifications using Firebase Cloud Messaging in all states, and in-app purchases (both one-off and subscription) via secure payment gateways. I also follow best-practice state management to maintain clean, testable code and ensure smooth integration into existing architectures. Unit and widget testing are always included so new features work reliably without breaking existing functionality. You are welcome to review my profile for similar mobile app projects I’ve completed with great results. Do you already have a preferred payment gateway in mind for the in-app purchase integration (e.g., Razorpay, Stripe, or another option)? Knowing this will help me tailor the solution to your needs. Thank you, James
