Flutter crypto App Deployment

I have a complete Figma design for an crypto mobile application and now need it built in Flutter and published under your own Google Play developer account. The core goal is to move from design files to a live, downloadable Android app that meets Google’s current policy requirements.

You will take my static screens, wire them up to Flutter code, hook in the back-end endpoints I supply, and walk the build all the way through Play Console review. Because the purpose of this project is strictly crypto, smooth product browsing and purchasing flow must remain central throughout your implementation.

Deliverables
• Fully functional Flutter project (Dart source, assets, pubspec.yaml) matching my approved UI
• Release-ready AAB signed with your Play signature, plus a debug build for testing
• Live Google Play listing link, store graphics, and final approval confirmation
• Basic hand-off guide so I can maintain future updates on my own account if needed

Acceptance criteria
• App installs and runs on Android 8.0+ without crashes
• All provided screens rendered pixel-perfect to the design
• Checkout flow completes successfully against the staging and production APIs I provide
• Passes Google Play policy and content review on first submission

Please let me know your estimated timeline to reach internal testing, how many rounds of QA you usually include before submission, and any previous Flutter e-commerce examples you can share.
