Flutter Riverpod Tutorial Series #10 - Placing Orders: Full Checkout Flow

Learn Flutter Riverpod from scratch by building a complete, production-quality e-commerce app (ShopWave) across 12 structured lessons. This is Lesson 10: Placing Orders: Full Checkout Flow

---
WHAT YOU'RE BUILDING
---
ShopWave is a full Flutter e-commerce app built with Riverpod 3.x and a Serverpod REST backend. Over 12 lessons you build every feature from scratch: JWT authentication with session restore, a product catalogue with detail screens, a shopping cart with immutable state, a complete checkout and order flow, a reactive dependency graph spanning 11 providers, structured error handling with Dio interceptors, shimmer loading states, and full unit tests with ProviderContainer.

By the end of the series, you understand not just how to use Riverpod but how to design with it.

WHAT THIS SERIES COVERS
---
✅ Every Riverpod provider type: Provider, NotifierProvider, AsyncNotifierProvider, .family, .autoDispose.
✅ The ref system: watch vs read vs listen, and when each belongs in build() vs action methods
✅ AsyncValue.when(): handling loading, error, and data states cleanly every time
✅ The three-tier dependency graph : infrastructure → auth bridge → business logic
✅ Immutable state mutations : why always-new-list is non-negotiable in Riverpod
✅ Token injection via authenticatedDioProvider : auth flows into every API call automatically
✅ Pull-to-refresh and retry with ref.invalidate
✅ The .family modifier : one declaration, unlimited parameterised instances
✅ Provider composition : how one login event cascades through 11 providers automatically
✅ Unit testing with ProviderContainer and mock overrides : no network required
✅ Dio error interceptors : converting raw exceptions into human-readable AppError types
✅ Shimmer skeleton loading states that match the real content shape
✅ riverpod_generator preview : the annotation approach and when to migrate

---
WHO THIS IS FOR
---
This series is for Flutter developers who already know the basics of Flutter and Dart, and want to stop guessing at state management and start designing with it. If you've worked through a beginner course and feel lost when your app grows beyond a few screens, this series builds the architectural intuition you're missing.

Prior experience with Provider or GetX helps but is not required. No Riverpod knowledge assumed.
