Riverpod
The next generation of Flutter state management and dependency injection. Riverpod is a complete rewrite of Provider, fixing its fundamental limitations — providers are global, compile-time safe, and testable without context. Riverpod 2.0 adds code generation (@riverpod annotation) and AsyncNotifier for async state. Handles loading/error/data states automatically with AsyncValue. Widely considered the best DI+state solution for Flutter.

⚙ Agent Friendliness
🔒 Security
Client-side library — no network exposure. State is in-memory only. ProviderScope isolation enables proper test/production separation. No serialization security concerns.
⚡ Reliability
Best When
You're building non-trivial Flutter apps and want a clean, testable, compile-time-safe approach to state management and dependency injection without Provider's context limitations.
Avoid When
Your Flutter app is simple with minimal shared state — Riverpod's learning curve isn't worth it for small apps. Use setState or Provider for straightforward cases.
Use Cases
- • Manage async API state in Flutter agent apps using AsyncNotifierProvider — automatically handles loading, error, and data states with built-in refresh
- • Implement dependency injection in Flutter using Riverpod providers — override providers in tests to inject mocks without BuildContext injection
- • Cache and share API responses across widgets using Riverpod's provider caching — avoids redundant network requests when multiple widgets need the same data
- • Combine multiple providers using ref.watch to build derived state — agent dashboards that compose data from multiple async sources
- • Implement scope-aware state with ProviderScope to isolate state per feature or user session in multi-tenant Flutter apps
Not For
- • Server-side Dart — Riverpod is Flutter-focused; use standard DI patterns for server-side Dart
- • Simple apps with minimal state — if you have fewer than 5 state objects, built-in setState or InheritedWidget may be sufficient
- • Developers who want MobX-style observable objects — Riverpod uses functional/declarative style; use MobX for object-oriented reactive state
Interface
Authentication
Riverpod is a state management library — no auth. Authentication state is typically managed as a Riverpod provider (authStateProvider) that other providers can watch.
Pricing
Riverpod is MIT licensed and free. Maintained by Remi Rousselet (also the author of Provider and Freezed).
Agent Metadata
Known Gotchas
- ⚠ ref.read vs ref.watch — ref.read inside build() misses updates; agents must use ref.watch for reactive state and ref.read only in callbacks/methods
- ⚠ Provider autodispose — @riverpod uses keepAlive: false by default; providers are destroyed when no longer listened; agents must use keepAlive: true for background state that outlives UI
- ⚠ Circular dependencies between providers cause runtime errors — design provider dependency graphs to be acyclic; circular deps are a design smell indicating state should be merged
- ⚠ Code generation with @riverpod requires running build_runner — forgetting to run 'dart run build_runner watch' after annotation changes causes stale generated code and confusing errors
- ⚠ Family providers create a new provider instance per argument — using mutable objects or large lists as family arguments creates memory leaks; use stable primitives (String, int) as family keys
- ⚠ Global provider container in tests requires ProviderContainer disposal — forgetting container.dispose() in tearDown leaks async operations between tests
