Prompt to a Running Flutter App

Build a Flutter app for tracking household maintenance. Users add appliances, schedule service reminders and attach receipts, with native navigation and layouts suited to both iOS and Android.

Include these capabilities:
- Complete Flutter/Dart project: screens, navigation, state management
- Live web preview — your app compiled and served in ~20–60s per build
- Backend, auth and database for real user state
- APK and AAB export for Android; store-submission scaffolding
- Full source export to continue in your own Flutter workflow

Build the complete working project with its routes, data model and interactions. For saved or private data, implement persistence, authentication and server-side permissions. Keep API credentials on the server. For external services, document the required setup and use test mode until real accounts are connected. Do not present a simulated integration as a completed live connection.

Make the interface responsive, with accessible labels, keyboard navigation and visible focus. Include loading, empty, validation and error states. Use clearly labelled sample data, never invented customer testimonials or results. Choose a visual direction suited to this project and keep typography, spacing and controls consistent. Explain how to run, test, export and deploy the source.

Verify this end-to-end flow:
Create a reminder on a physical phone, restart the app and check saved attachments. Verify denied-notification and offline states on both target platforms.
