Flutter Captcha Typing App Development

I’m building a full-featured captcha-typing platform in Flutter and need an end-to-end codebase that is production-ready. The core flow is simple—users sign up with email and password, solve text, image, or audio captchas, and earn points—but I want it wrapped in a polished, monetisable product. Main feature set • Captcha engine that serves all three formats (text, image, audio) with smooth switching and fail-safe fallback. • Reward mechanics: daily log-in bonus, weekly streak bonus, and a referral programme that credits bonus points to both inviter and invitee. • Subscriptions available in four tiers—daily, weekly, monthly, yearly—with paywall and upgrade / downgrade logic handled inside the app. • In-app AdMob (or similar) banners, interstitials, and rewarded ads integrated cleanly into the solving flow. • A built-in admin panel (no separate web dashboard) where I can: – Push new captcha batches or toggle providers – View real-time analytics (active users, captchas solved, ad impressions, revenue, referral stats) – Adjust reward rates and commissions on the fly Tech expectations Flutter 3.x with null-safety, Firebase (or an equivalent backend) for auth, cloud functions for referral and bonus logic, and a lightweight SQL/NoSQL store for captcha metadata. State management is up to you, but I prefer Riverpod or Bloc for clarity. The code should be modular, well-commented, and easy to extend. Deliverables 1. Complete Flutter source with assets and build scripts 2. Embedded admin module with secure role-based access 3. Documentation covering build steps, environment variables, and how to add new captcha types or ad networks 4. A short hand-off call or screen-share to walk me through deployment to both Android and iOS TestFlight Acceptance criteria • All authentication, reward, and subscription flows work flawlessly on physical devices (Android & iOS) • Captchas render in under 1 s on mid-range hardware • Admin analytics refresh in real time (≤5 s lag) • No blocker-level issues in Google Play / App Store pre-check If this sounds like your wheelhouse, let’s talk timelines and any library preferences you have. I need to include the anti fraud system, and ay other tyoes of frauds should be avoided by including that systems
