Class Statics
The batching engine behind reactivity. Signals queue their dependents here, and Scheduler drains them on a microtask. Most code reaches it through the free functions on Flushing rather than the class.
flush, scheduleFlush, afterFlush, and getSource are exported from @semantic-ui/reactivity as standalone functions bound to these statics. Import those instead of touching Scheduler directly.

Class Statics
Scheduler exposes its queues and flags as statics. They are read by the reactivity internals, treat them as observable state, not as a public mutation surface.
current
Scheduler.current;The reaction currently executing, or null outside a flush. Prefer currentReaction() to read it.
Returns
A Reaction or null.
pendingReactions
Scheduler.pendingReactions;The Set of reactions queued for the next flush.
Returns
Set<Reaction>.
afterFlushCallbacks
Scheduler.afterFlushCallbacks;The array of callbacks queued to run after the next flush drains.
Returns
Array<() => void>.
isFlushScheduled
Scheduler.isFlushScheduled;Whether a flush is already queued on the microtask, used to keep scheduleFlush idempotent.
Returns
boolean.
isFlushing
Scheduler.isFlushing;Whether a flush is currently draining.
Returns
boolean.
maxFlushIterations
Scheduler.maxFlushIterations;The pass cap before flush declares a reactive cycle and clears its queues. Defaults to 100.
Returns
number.
scheduleReaction
Scheduler.scheduleReaction(reaction);Queues a reaction for the next flush and schedules one. Called by signals when a dependency changes, not part of the application surface.
