- AnimationStatus status
Calls all the status listeners.
If listeners are added or removed during this function, the modifications will not change which listeners are called during this iteration.
Implementation
void notifyStatusListeners(AnimationStatus status) {

yield DiagnosticsProperty<AnimationLocalStatusListenersMixin>(
'The $runtimeType notifying status listeners was',
this,
style: DiagnosticsTreeStyle.errorProperty,
