no setterinherited
hashCode int

isInfinite bool
Will the effect continue to run forever (never completes)?

no setterinherited

Methods

advance(double dt) double
Advances this controller's internal clock by dt seconds.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
onMount(Effect parent) → void
This is called by the Effect class when the controller is attached to that effect. Controllers with children should propagate this to their children.
override
recede(double dt) double
Similar to advance(), but makes the effect controller move back in time.
inherited
setToEnd() → void
Puts the controller into its final "completed" state.
override
setToStart() → void
Reverts the controller to its initial state, as it was before the start of the animation.
override
toString() String
A string representation of this object.
