Lx class

The global entry point for the Levit reactive engine.

Lx provides static access to core functionality, including configuration, dependency tracking, and batching.

asyncComputedTrackerZoneKey → Object: Internal: Zone key for identifying the active async computed tracker.
no setter

getter/setter pair
isBatching → bool: Returns true if a batching operation is currently in progress.
no setter
listenerContext → LxListenerContext?: Returns the current active listener context, if any.
no setter
proxy ↔ LevitReactiveObserver?: The active observer capturing dependencies.
getter/setter pair

addMiddleware(LevitReactiveMiddleware middleware) → LevitReactiveMiddleware: Registers a new LevitReactiveMiddleware to intercept or observe state changes.
batch<R>(R callback()) → R: Executes callback in a synchronous batch.
batchAsync<R>(Future<R> callback()) → Future<R>: Executes asynchronous callback in a batch.
clearMiddlewares() → void: Removes all active middlewares.
containsMiddleware(LevitReactiveMiddleware middleware) → bool: Checks if a particular middleware is currently registered.
enterAsyncScope() → void: Internal: Enters an asynchronous tracking scope.
exitAsyncScope() → void: Internal: Exits an asynchronous tracking scope.
removeMiddleware(LevitReactiveMiddleware middleware) → bool: Unregisters a previously added middleware.
runWithContext<T>(LxListenerContext context, T fn()) → T: The context is passed to LevitReactiveMiddleware.startedListening and LevitReactiveMiddleware.stoppedListening.
runWithoutMiddleware(void action()) → void: Executes action while temporarily bypassing all registered middlewares.
runWithOwner<T>(String ownerId, T fn()) → T: Executes fn while associating any created reactive variables with ownerId.
