⚡ bloc_signals_riverpod "With the rigor of BLoC and the flex and speed of Signals" Bidirectional interoperability adapters and extensions connecting BlocSignal / CubitSignal state containers with Riverpod providers.

Supports both Riverpod 2.x and Riverpod 3.x out of the box.

🌐 Ecosystem Packages #

The BlocSignal monorepo consists of 11 modular packages:

Package	Version	Description
bloc_signals		Core pure Dart reactive state primitives bridging BLoC & Signals
bloc_signals_flutter		Flutter UI bindings, providers, builders, listeners & selectors
bloc_signals_bloc		Classic BLoC 8/9 interop adapters & bidirectional event bridges
bloc_signals_riverpod		Bidirectional Riverpod 2/3 interop adapters & provider extensions
bloc_signals_jaspr		Jaspr web component integration and state binding for BlocSignal
bloc_signals_hydrate		Automated synchronous local state persistence & hydration
bloc_signals_replay		Undo & redo state history tracking for CubitSignal and BlocSignal
bloc_signals_otel		OpenTelemetry tracing and span generation for state transitions
bloc_signals_devtools		Universal DevTools telemetry observer using dart:developer
bloc_signals_test		Declarative unit testing utilities (blocSignalTest)
bloc_signals_lint		Custom analyzer lint rules & automated IDE quick-fixes

⚡ Key Features #

• 🔄 Bidirectional toBlocSignal(refOrContainer): Convert any Riverpod NotifierProvider, AsyncNotifierProvider, StateNotifierProvider, StateProvider, or StreamNotifierProvider into a RiverpodNotifierBlocSignal exposing the typed .notifier to trigger mutations directly from BlocSignal consumers.
• 🔀 Bidirectional BlocSignalBase.toProvider(): Expose any BlocSignal or CubitSignal as a cached Riverpod NotifierProvider, giving Riverpod widgets direct read access and typed .notifier.cubit / .notifier.bloc mutation handles with optional autoClose lifecycle management.
• 🔒 Automatic ref.onDispose Registration: Passing ref into toBlocSignal(ref) inside Riverpod providers automatically binds ref.onDispose(bloc.close) for zero-boilerplate lifecycle management.
• ⚡ Universal Riverpod Support: Built for riverpod: ">=2.5.0 <4.0.0", supporting Riverpod 2.x and Riverpod 3.x seamlessly.

🚀 Getting Started #

Add bloc_signals_riverpod to your pubspec.yaml:

dependencies:
  riverpod: ^2.5.0 # or ^3.0.0
  bloc_signals: ^1.0.0
  bloc_signals_riverpod: ^1.0.0

💡 Quick Examples #

1. Riverpod → BlocSignal (Bidirectional Read & Mutate) #

Adapt any Riverpod notifier provider into a RiverpodNotifierBlocSignal inside a Riverpod provider using ref:

import 'package:bloc_signals_riverpod/bloc_signals_riverpod.dart';
import 'package:riverpod/riverpod.dart';

final counterProvider = NotifierProvider<CounterNotifier, int>(
  CounterNotifier.new,
);

// Convert Riverpod provider to BlocSignal container with automatic ref.onDispose binding
final counterBlocProvider = Provider.autoDispose<
    RiverpodNotifierBlocSignal<CounterNotifier, int>>((ref) {
  return counterProvider.toBlocSignal(ref);
});

// In your BlocSignal consumer or widget:
final bloc = ref.watch(counterBlocProvider);

// Read reactive state:
print(bloc.stateValue);

// Mutate upstream Riverpod notifier directly:
bloc.notifier.increment();

2. Riverpod → BlocSignal (ProviderContainer) #

Using a standalone ProviderContainer:

final container = ProviderContainer();
final riverpodBloc = counterProvider.toBlocSignal(container);

// State is synchronously in sync with Riverpod!
print(riverpodBloc.stateValue);

// Mutate Riverpod notifier:
riverpodBloc.notifier.increment();

// Clean up subscription when finished:
await riverpodBloc.close();

3. BlocSignal → Riverpod (Bidirectional Read & Mutate) #

Expose a BlocSignalBase state container as a standard Riverpod NotifierProvider:

import 'package:bloc_signals_riverpod/bloc_signals_riverpod.dart';
import 'package:riverpod/riverpod.dart';

final counterCubit = CounterCubit(initialState: 0);

// Convert to Riverpod NotifierProvider
final counterProvider = counterCubit.toProvider();

// Watch state in Riverpod context:
final count = ref.watch(counterProvider);

// Mutate cubit/bloc directly via Riverpod notifier handle:
ref.read(counterProvider.notifier).cubit.increment();
// Or for event-based blocs:
// ref.read(counterProvider.notifier).bloc.add(const IncrementEvent());

🤖 AI Coding Assistant Skill #

This package is supported by an official pre-packaged AI Coding Skill representing architectural best practices, Riverpod 2/3 migration patterns, and bidirectional state bridge rules for BlocSignal.

If you develop with AI coding assistants (such as Claude Code, Antigravity, Gemini, Cursor, or Codex), you can load the bloc-signals skill bundle to guide your assistant's code generation and analysis.
