Hello, I have 10+ years of experience and have delivered multiple production-grade FlutterFlow apps using Maps, Stripe subscriptions, backend integrations, custom widgets, and admin panels. I WILL PROVIDE 2 YEARS FREE ONGOING SUPPORT AND COMPLETE SOURCE CODE; WE WILL WORK WITH AGILE METHODOLOGY AND I WILL ASSIST YOU FROM ZERO TO PUBLISHING ON STORES. 1. Portfolio (3 FlutterFlow apps): • Logistics Tracking App – Google Maps with custom markers + clustering (video link available). • Health Subscription App – Stripe subscriptions w/ free trials & webhooks (video + TestFlight). • Field Service CRM – FlutterFlow Web Admin panel + CSV import/export (demo available). 2. Backend Choice (Supabase or Firebase?): I recommend Supabase for this project because Row-Level Security rules, SQL flexibility, and webhooks simplify subscription sync, geodata queries, analytics storage, and admin workflows. Firebase is also possible if preferred. 3. Stripe Subscription Experience: Yes—implemented monthly/annual plans, free trials, and 5 webhook event handlers. Approach: Stripe → Supabase webhook → update user.subscription_status → FlutterFlow checks status before unblurring data. Also integrate trial handling and payment_failed flows. 4. Quote: I can give a fixed-price estimate after reviewing the full SOW, but based on scope, this falls into a standard full-production build range. Thanks.

Hello, As an experienced FlutterFlow developer, I have successfully built and deployed over 5 apps in the App Store and Google Play Store that utilize both Google Maps integration with custom markers and Stripe subscriptions with webhooks - two critical components of your clinical trial discovery app. I understand the importance of blurring facility/sponsor names until subscribers are identified as part of your paywall logic, and I have the skills to execute this using custom widget development. My clients have appreciated my keen eye for detail in building backend setups and admin panels, as well as handling CSV import/export gracefully to avoid any data errors. In terms of backend setup preference, I am well-versed in both Supabase and Firebase. Based on my evaluation of your requirements, I would recommend Firebase for this project as it offers a concise integration for FlutterFlow native authentication that you need, including email/password + optional Google Sign-In. Rest assured, my goal is to make sure everything works seamlessly together. To give you an example of my approach to Stripe subscription payments with free trials and webhooks in FlutterFlow: I follow clear communication channels, setting up automated messages at crucial stages like trial end warnings or payment failures. This helps maintain transparency between app users and you as the owner. Given my past track record with apps similar to yours which encompass Thanks!

Hi I can build this production-grade FlutterFlow application with fully integrated Google Maps, Stripe subscriptions, Supabase/Firebase backend, CSV tools, and a custom pixelation widget engineered for locked study data. A major technical challenge here is synchronizing subscription state in real time across paywall logic, map markers, drawer states, and “Apply Now” flows; I solve this by using robust webhook handling, cached status checks, and secure backend validation instead of relying solely on client-side checks. I have deep experience with FlutterFlow custom widgets, Stripe trials + webhooks, Google Maps clustering, and admin-panel workflows, ensuring smooth performance and reliable data entry pipelines. The connector between admin panel → geocoding → study table will be structured with validation layers to avoid broken coordinates or incomplete studies. Push notifications, analytics tracking, and saved-study logic will also tie cleanly into the same backend to maintain consistency across platforms. I’ll ensure your entire build remains editable in your FlutterFlow account with clean schema design and well-documented integrations. Thanks, Hercules
