Flutter Riverpod 3: Beyond State Management

Explore how Riverpod 3 introduces mutation to manage the lifecycle of actions, separating action logic from state and automating loading, success, and error states.

Preview a Flutter Riverpod todo legacy app demo with all, completed, and pending tabs, add/update/delete actions, a todo model using uuid and equatable, and snackbar notifications with a progress indicator.

Define a todo list state with a TodoListStatus enum and TodoListState class, manage loading, success, and error flows, and track deleting item and transient failures using Riverpod providers.

Create a Flutter Riverpod async notifier todo list provider that persists todos with shared preferences, decodes JSON to Todo via fromJson, encodes with toJson, and updates state with AsyncData.

Learn to build a todo app with flutter riverpod 3, implementing update and delete flows via AsyncData, and creating derived providers for completed counts and filtered todos.

Create a Riverpod-based Flutter todo app with home, add, and update pages, using consumer widgets and ref.watch to handle async data and tabs for all, completed, and pending todos.

Build add and update todo pages in flutter riverpod 3, using TextEditingController with disposal, snackbars for success or failure. React to TodoListStatus via ref.listen and return to HomePage on success.

Build a todo app with Flutter Riverpod 3 beyond state management, covering add, update, and delete workflows, UI feedback, and robust error handling using mutations and retry control.

Refactor the legacy todo app into a todo_mutation app using addTodoMutation, updateTodoMutation, and deleteTodoMutation. Harness Riverpod mutation lifecycles with AsyncNotifier and AsyncValue to streamline state and UI changes.

refine ui updates in a riverpod mutation-driven todo app by wiring delete, add, and update mutations, listening to mutation states, and displaying snackbars for success or error.

Test and refine a todo_mutation app by adding, editing, and deleting items with mutation-driven state, using per-item listeners, a snack bar, and error handling via run, ignore, and catchError.

Explore a flutter riverpod edge case where a snackbar vanishes after deleting a todo due to optimistic UI and lifecycle, and learn a safe onPressed async deletion flow.

Explore how provider and mutation differ, separating the todoListProvider state from the lifecycle of actions managed by mutations like addTodoMutation, updateTodoMutation, and deleteTodoMutation.

Create a login_legacy app with Riverpod, simulating login via an in-memory auth repository, and refactor from a provider/notifier flow to a lighter mutations-based approach.

Learn to replace the login notifier with a loginMutation in the Flutter Riverpod 3 course, connecting AuthRepository via MutationTransaction and organizing login logic in LoginActions.

Learn how to use a non-void type T for mutations in Riverpod, returning a value from the run function and displaying it through MutationSuccess for responsive UI.

Riverpod 3 adds offline persistence that automatically saves and restores notifier state via a storage interface and the persist function, using json encoding through toJson and fromJson.

Create a todo_mutation_sql app and implement riverpod offline persistence with riverpod_sqflite, sqflite, and path, including storage_provider.dart and TodoList persistence for offline-first UI.

Learn to replace riverpod_sqflite with shared preferences by implementing SharedPrefsStorage, wiring read, write, delete, and deleteOutOfDate in a todo_mutation_shared app, and verify cache behavior with hot restarts.

Explore Riverpod 3 automatic retry: exponential backoff, per-provider retry with a custom myRetry function, distinguish errors from exceptions, and offline-first UI using cached data.

Learn Riverpod 3 pause and resume features, including manual and automatic modes, and how to pause a listener with a subscription object. It covers visibility pausing, rebuild pauses, cascading suspensions.

Riverpod 3 adds ref.mounted to stop state updates after a provider is disposed during async tasks. Always check ref.mounted after await to safeguard updates.

Explore Riverpod 3 provider lifecycle changes focusing on safe state management and resource optimization. Learn about disposed ref errors, provider exceptions, automatic pausing of providers, and maintaining subscriptions during rebuilds.

Discover Riverpod 3's generic support with type parameters and code generation, creating a single GenericList blueprint that yields concrete lists like string or int through type T.

Riverpod 3 unifies all provider interfaces into a single notifier for easier manual and code-generated provider creation. It uses equality checks and a sealed AsyncValue.

Create a scoped counter app with riverpod by building a counter notifier, wrapping the app in provider scope, and using overrides to compare keepAlive behavior across two pages with scopedCounterProvider.

Explore a scope optimized flutter riverpod app by building an item list notifier, overriding currentItemProvider with ProviderScope, and comparing no scoping and scoping for performance.

Explore how to scope Riverpod providers to alter themes within specific widget trees in a Flutter app, using a level-based color scheme and provider overrides.

Refactor a prop drilling app by introducing provider scope to access product data via currentProductProvider, replacing parameter passing with riverpod providers for product list and detail.

Discover how Riverpod 3 streamlines testing with ProviderContainer.test and WidgetTester.container. Learn to use ProviderScope overrides to control notifiers and asynchronous state during tests.

Practice unit testing Riverpod's storageProvider by mocking SharedPreferences with Mocktail, verifying storage creation, write, read, and delete operations in an isolated test environment using ProviderContainer.

Test completedCountProvider using provider container and overrideWithBuild with mockTodos to verify correct counted completed items, then verify zero for an empty list, then prepare to test filteredTodosProvider.

Learn how to unit test the filteredTodosProvider with ProviderContainer and overrides, using mock todos to verify all, completed, and pending filters and their updatedAt descending order.

Demonstrates testing a Riverpod todoListProvider by mocking SharedPreferences instead of SharedPrefsStorage, wiring a test ProviderContainer with storage overrides, stubbing getString and setString, and validating initial data and completed count.

Execute integration tests for todoListProvider mutations, ensuring state changes and asynchronous persistence to SharedPreferences. Learn mocking strategies, tsx.get usage, and transition to fake storage for robust tests.

Clarifies the difference between mock and fake in Riverpod 3 testing, showing how fake storage uses memory to test business logic while mocks verify behavior.

Test a Riverpod todo list with fake storage using ProviderContainer, set up, and mutation tests (add, update, delete) to verify data persistence and completion counts.
