# Flutter 11: To'liq Loyiha — Desktop & Mobile Kross-Platforma Dashboard & Store App

> **Holat:** 2026-yil. Nazariy bilimlarni mustahkamlashning eng yaxshi yo'li — bu barcha qismlarni (Dart 3, Clean Architecture, REST API, Dio, Riverpod, Desktop & Mobile moslashuvchan interfeys) birlashtirgan to'liq ishlab chiqarish (production-ready) loyihasini qurishdir. Ushbu darsda biz macOS, Windows, iOS va Android'da birdek mukammal ishlaydigan "DevStore Hub" — zamonaviy e-commerce dashboard ilovasini noldan quramiz.

## 1. Loyiha konsepsiyasi va UI/UX xaritasi {#loyixa-xaritasi}

Loyihamiz — bu tovarlar ro'yxatini real REST API orqali olib keluvchi, qidiruv, saralash, tahlil qilish va savatchaga qo'shish imkoniyatiga ega boshqaruv paneli (Dashboard) hisoblanadi.
