EventBus(): factory

Properties

eventHistory → List<ModuleEvent>: Get all event history
no setter
eventMiddlewareCount → int: Get current middleware counts for debugging and monitoring.
no setter
hashCode → int: The hash code for this object.
no setterinherited
hasListeners → bool: Whether any listeners are currently registered.
no setterinherited
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited

no setter
signalMiddlewareCount → int: no setter

Methods

addListener(VoidCallback listener) → void: Register a closure to be called when the object changes.
inherited
addMiddleware(EventMiddleware middleware) → void: Add an event middleware for processing or filtering events.
addSignalMiddleware(SignalMiddleware middleware) → void: Add a signal middleware for processing or filtering named signals.
cancel(EventSubscription subscription) → void: Cancel a specific subscription
cancelModuleSubscriptions(String moduleId) → void: Cancel all subscriptions from a module
clearAll() → void: Clears all subscriptions and histories.
dispose() → void: Dispose resources
override
emit<T extends ModuleEvent>(T event) → void: Emit an event to all subscribers with built-in rate limiting protection.
emitAsync<T extends ModuleEvent>(T event) → Future<void>: Emit an event asynchronously (non-blocking)
emitSignal(String signalName, {dynamic data, String? sourceModuleId, ModuleIdentityToken? identityToken}) → void: Emit a named signal with identity verification and rate limiting.
getRecentEvents<T extends ModuleEvent>({int limit = 10}) → List<T>: Get recent events of a specific type
hasSubscribers<T extends ModuleEvent>() → bool: Check if there are subscribers for an event type
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
notifyListeners() → void: Call all the registered listeners.
inherited
on<T extends ModuleEvent>(void callback(T event), {String? subscriberModuleId, Duration? timeout}) → EventSubscription: Subscribe to events of a specific type Returns a subscription that can be cancelled
onAutoDispose<T extends ModuleEvent>(void callback(T event), {String? subscriberModuleId, Duration? timeout}) → EventSubscription: Subscribe to events and auto-dispose when widget is disposed Use with StatefulWidget's dispose method
onSignal(String signalName, void callback(dynamic data), {String? subscriberModuleId, Duration? timeout}) → EventSubscription: Subscribe to a named signal (String-based event) Use this for zero-import communication between modules
removeListener(VoidCallback listener) → void: Remove a previously registered closure from the list of closures that are notified when the object changes.
inherited
removeMiddleware(EventMiddleware middleware) → void: Remove an event middleware from the chain.
removeSignalMiddleware(SignalMiddleware middleware) → void: Remove a signal middleware from the chain.
setRateLimitConfig(RateLimitConfig config) → void: Configure rate limiting
subscriberCount<T extends ModuleEvent>() → int: Get subscriber count for an event type
toString() → String: A string representation of this object.

Operators

operator ==(Object other) → bool: The equality operator.
