Debouncer class final

A practical Debouncer for optimizing performance by controlling the frequency of function calls in response to rapid events.

Constructors

Debouncer({required Duration delay, FutureOr<void> onStart()?, FutureOr<void> onWaited()?, FutureOr<void> onCall()?})

delay → Duration: The delay before calling the _onWaited function.
final
hashCode → int: The hash code for this object.
no setterinherited
isPending → bool: Whether a debounce window is currently open — i.e. a call has been made and the delay has not yet elapsed (and the debouncer has not been cancelled or finalized).
no setter
onCall → _VoidCallback?: no setter
onStart → _VoidCallback?: no setter
onWaited → _VoidCallback?: no setter
runtimeType → Type: A representation of the runtime type of the object.

call({FutureOr<void> onStart()?, FutureOr<void> onWaited()?, FutureOr<void> onCall()?}) → FutureOr<void>: Calls the onCall function and then waits for delay before calling the onWaited function.
cancel() → bool: Cancels any pending wait. Returns true if a wait was actually cancelled, false if there was nothing pending.
dispose() → void: Cancels any pending wait and resets the debouncer. The pending onWaited callbacks are dropped (use finalize to flush them instead). The instance can still be reused after dispose.
finalize({FutureOr<void> onWaited()?}) → FutureOr<void>: Finalizes the debouncer: cancels the pending timer (if any) and immediately runs the onWaited callbacks. Resets the started state so that the next call will fire onStart again.
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
toString() → String: A string representation of this object.
