Properties
- hashCode → int
-
The hash code for this object.
no setterinherited
- needsScreenSize → bool
-
When true, instructs AnimatorWidget to preRender the child without
animation and extracts the screen-size in order to supply it to
AnimationDefinition.build() in the next render.
finalinherited
- needsWidgetSize → bool
-
When true, instructs AnimatorWidget to preRender the child without
animation and extracts the child's size in order to supply it to
AnimationDefinition.build() in the next render.
finalinherited
- preferences → AnimationPreferences
-
Pass AnimationPreferences to setup offset, duration, autoPlay and
add an AnimationStatusListener
finalinherited
- preRenderOpacity → double
-
Sets the visibility of the child during the preRender when
needsWidgetSize or needsScreenSize is set to true.
Use this property to prevent 'flickering' when rendering in-animations.
finalinherited
- runtimeType → Type
-
A representation of the runtime type of the object.

Methods
-
build(
BuildContext context, Animator animator, Widget child) → Widget -
AnimatorWidget calls build to retrieve the animated Widget.
The extracted Animator from the getDefinition phase is injected to
supply a controller and the Animation objects.
Example:
@override
Widget build(BuildContext context, Animator animator, Widget child) {
return FadeTransition(
opacity: animation.get('opacity'),
child: child,
);
}
override
-
getDefinition(
{Size? screenSize, Size? widgetSize}) → Map< String, TweenList> -
AnimatorWidget calls getDefinition to gather the animation. Animations
are defined using named TweenLists using a Map<String, TweenList>.
Example:
@override
Map<String, TweenList> getDefinition({Size screenSize, Size widgetSize}) {
return {
"opacity": TweenList
override
-
