ZigzagEffectController class

This effect controller goes from 0 to 1, then back to 0, then to -1, and then again to 0.

This is similar to an alternating controller, except that it treats the starting position as the "middle ground", and oscillates around it.

Combine with RepeatedEffectController or InfiniteEffectController in order to create longer zigzags.

Inheritance

Constructors

completed → bool: Has the effect already finished?
no setterinherited
duration ↔ double: Total duration of the effect. If the duration cannot be determined, this will return null. For an infinite effect the duration is infinity.
getter/setter pairinherited
hashCode → int: The hash code for this object.
no setterinherited
isInfinite → bool: Will the effect continue to run forever (never completes)?
no setterinherited
isRandom → bool: Is the effect's duration random or fixed?
no setterinherited
progress → double: The current progress of the effect, a value between 0 and 1.
no setteroverride
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited
started → bool: Has the effect started running? Some effects use a "delay" parameter to postpone the start of an animation. This property then tells you whether this delay period has already passed.
no setterinherited
timer → double: no setterinherited

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.
inherited
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.
inherited
setToStart() → void: Reverts the controller to its initial state, as it was before the start of the animation.
inherited
toString() → String: A string representation of this object.
