hasRunningAnimations property

bool get hasRunningAnimations

Whether there are any transient callbacks scheduled.

This essentially checks whether all animations have completed.

See also:

pumpAndSettle, which essentially calls pump until there are no scheduled frames.
SchedulerBinding.transientCallbackCount, which is the value on which this is based.
SchedulerBinding.hasScheduledFrame, which is true whenever a frame is pending. SchedulerBinding.hasScheduledFrame is made true when a widget calls State.setState, even if there are no transient callbacks scheduled. This is what pumpAndSettle uses.

Implementation

bool get hasRunningAnimations => binding.transientCallbackCount > 0;
