Flutter Todo List Tutorial

The tutorial targets mobile platforms (Android and iOS) and is demonstrated on emulators and physical devices. It notes emulator networking differences (iOS use 127.0.0.1, Android use 10.0.2.2) and recommends using the host machine IPv4 for real devices.

State is managed with Riverpod: StateNotifierProvider for the Todo list, StateProvider for simple state like filters, and Provider for derived values. AsyncValue is used for async state and flutter_hooks/hooks_riverpod are used for lifecycle management.

Persistence is optional via a REST API (example Phoenix backend). The app uses a TodoRepository with an injected http Client to fetch, create, and update todos; the repository is exposed through a repositoryProvider for use and testing.

The project includes flutter_test for unit/widget tests and structures the repository to allow mocking the http Client. It also uses build_runner and riverpod_generator for Riverpod code generation.
