FlutterFlow Actions, IAP & Offline

I already built the core UI for my cross-platform AAC communication app in FlutterFlow, but the project now needs real functionality. I’m looking for a developer who can jump straight into my existing FlutterFlow project file and wire up the logic that is still missing.

Key pieces of work
• Implement subscription-based in-app purchases for both iOS and Android, handling Apple/Google review requirements and graceful downgrade or renewal flows.
• Build reliable offline support: when the user has no connection the app must still load and run a defined set of limited core features, then sync automatically once connectivity returns.
• Finish all navigations and routing so every screen in the current prototype opens with the correct parameters, back-stack behaviour is predictable, and deep links can be added later.

Tech context
The visual tree, widgets, and basic data models are already in place inside FlutterFlow; I need custom Dart code only where FlutterFlow actions fall short, and clean documentation so I can keep maintaining the project myself.

Acceptance
1. I can run the updated project in FlutterFlow, export to Xcode & Android Studio and compile without extra fixes.
2. Test seats demonstrate:
– a new user purchasing a subscription, restoring it, and seeing premium features unlock;
– the app opening fully offline and exposing only the agreed limited feature set;
– every navigation path working from splash to settings and back.
3. All code and configuration are committed back to my Git repo with concise comments.

If this sounds straightforward to you, let’s talk timelines and milestones so we can push the build to TestFlight and internal testing on Google Play as soon as possible.
