Flutter Dual-Platform App Build

I already have two complete app concepts: every screen, interaction and asset is designed, documented and ready to hand over. What I need now is the engineering muscle to turn those polished Figma files into production-ready Flutter applications that run smoothly on both iOS and Android.

Both apps share a common backend. The REST endpoints, data models and authentication flow are all mapped out, so your focus will be wiring the UI to those services, managing state cleanly and ensuring offline resilience where needed. I expect pixel-perfect implementation of the provided designs, faithful reproduction of the planned user journeys and thoughtful handling of edge cases across devices.

Deliverables
• Full Flutter codebase for the two apps, structured for reuse of shared components
• Integrated API layer (Dio / http / GraphQL—your call, so long as it’s clean and documented)
• Working builds: one TestFlight bundle, one Google Play internal test bundle for each app
• README with setup steps, environment variables and a short note on the chosen state-management pattern
• Post-handover support for initial store submission fixes (bug-fix window, 2 weeks)

Acceptance criteria
1. All screens match the supplied designs at ≤2 px variance.
2. End-to-end flows (signup, login, core feature sets) pass the provided Postman test suite.
3. Both apps achieve 60 fps on mid-range devices and score ≥90 on Flutter’s “flutter analyze” with no warnings.

If you have a track record of shipping Flutter apps to both App Store and Play Store and you’re comfortable integrating with existing APIs, let’s move forward—I’ll share the design links, API docs and a Slack channel for quick iteration.
Both applications will share a single backend system and database. The developer should structure the project to support shared services and scalable architecture.
