Bolt ⚡ #

A minimal, ultra-high-performance event-driven state management .

Features #

• Strict Event-Driven Contract: Keep your business logic isolated. UI only communicates via explicit events.
• Zero Inbound Overhead: No stream buffers or microtask delays between event dispatch and execution.

Quick Start #

1. Define Events and State #

Leverage modern Dart sealed classes for type-safe event payloads:

sealed class CounterEvent { const CounterEvent(); }
class Increment extends CounterEvent { const Increment(); }
class Decrement extends CounterEvent { const Decrement(); }

2. Create your Bolt Container #

Implement the synchronous/asynchronous onEvent handler:

class CounterBolt extends Bolt<CounterEvent, int> {
  CounterBolt() : super(0);

  @override
  void onEvent(CounterEvent event) {
    switch (event) {
      case Increment(): emit(state + 1);
      case Decrement(): emit(state - 1);
    }
  }
}
