CallbackController class abstract

Limits the frequency with which a callback is called to one call per duration.

To run the callback as soon as possible use CallbackController.limiter. To delay the execution by duration use CallbackController.delayer.

current ↔ TimeStampedCallbackControllerState: The current state.
getter/setter pair
duration → Duration: After the event delaying is added the stream will wait for at least duration before the event CallbackControllerState.ready is added.
final
hashCode → int: The hash code for this object.
no setterinherited
hasTimedOut → bool: Returns true if the last state added to stream was delaying and DateTime.now is after current.dateTimeStamp plus duration.
no setter
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited
stream → Stream<CallbackControllerState>: A stream with events of type CallbackControllerState.
no setter

close() → Future: Closes the controller such that no further events will be added to stream. Any unfinished timers will be cancelled.
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
