SlideEffect class

Effect that moves the target based on a fraction of its size (via SlideTransition) based on the specified begin and end offsets. Defaults to begin=Offset(0, -0.5), end=Offset.zero (ie. slide down from half its height).

To use pixel offsets instead, use MoveEffect.

Properties

begin Offset?
The begin value for the effect. If null, effects should use a reasonable default value when appropriate.
finalinherited
curve Curve?
The specified curve for the effect. If null, will use the curve from the previous effect, or Animate.defaultCurve if this is the first effect.
finalinherited
delay Duration?
The specified delay for the effect. If null, will use the delay from the previous effect, or Duration.zero if this is the first effect.
finalinherited
duration Duration?
The specified duration for the effect. If null, will use the duration from the previous effect, or Animate.defaultDuration if this is the first effect.
finalinherited
end Offset?
The end value for the effect. If null, effects should use a reasonable default value when appropriate.

Methods

build(BuildContext context, Widget child, AnimationController controller, EffectEntry entry) Widget
Builds the widgets necessary to implement the effect, based on the provided AnimationController and EffectEntry.
override
buildAnimation(AnimationController controller, EffectEntry entry) Animation<Offset>
Returns an animation based on the controller, entry, and begin/end values.
inherited
getBeginRatio(AnimationController controller, EffectEntry entry) double
Returns a ratio corresponding to the beginning of the specified entry.
inherited
getEndRatio(AnimationController controller, EffectEntry entry) double
Returns a ratio corresponding to the end of the specified entry.
inherited
getOptimizedBuilder<U>({required ValueListenable<U> animation, Widget? child, required TransitionBuilder builder}) AnimatedBuilder
Returns an optimized AnimatedBuilder that doesn't rebuild if the value hasn't changed.
inherited
getToggleBuilder({required ValueListenable<double> animation, required Widget child, required bool toggle(), required ToggleEffectBuilder builder}) AnimatedBuilder
Returns an AnimatedBuilder that rebuilds when the boolean value returned by the toggle function changes.
inherited
isAnimationActive(Animation animation) bool
Check if the animation is currently running / active.
inherited

Invoked when a nonexistent method or property is accessed.
inherited
toString() String
