JsonAnimatedCrossFadeBuilderModel class

Creates a cross-fade animation widget.

The duration of the animation is the same for all components (fade in, fade out, and size), and you can pass Intervals instead of Curves in order to have finer control, e.g., creating an overlap between the fades.

Properties

alignment → AlignmentGeometry
How the children should be aligned while the size is animating.
final
args → Map<String, dynamic>
finalinherited
crossFadeState → CrossFadeState
The child that will be shown when the animation has completed.
final
duration → Duration
The duration of the whole orchestrated animation.
final
excludeBottomFocus → bool
When true, this is equivalent to wrapping the bottom widget with an ExcludeFocus widget while it is at the bottom of the cross-fade stack.
final
firstChild → JsonWidgetData
The child that is visible when crossFadeState is CrossFadeState.showFirst. It fades out when transitioning crossFadeState from CrossFadeState.showFirst to CrossFadeState.showSecond and vice versa.
final
firstCurve → Curve
The fade curve of the first child.
final
hashCode → int
The hash code for this object.
no setterinherited
layoutBuilder → dynamic
A builder that positions the firstChild and secondChild widgets.
final
reverseDuration → Duration?
The duration of the whole orchestrated animation when running in reverse.
final
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
secondChild → JsonWidgetData
The child that is visible when crossFadeState is CrossFadeState.showSecond. It fades in when transitioning crossFadeState from CrossFadeState.showFirst to CrossFadeState.showSecond and vice versa.
final
secondCurve → Curve
The fade curve of the second child.
final
sizeCurve → Curve
The curve of the animation between the two children's sizes.
final

Methods

noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
toJson() → Map<String, dynamic>
Abstract function that concrete classes must implement. This must encode the internal data model to a JSON compatible representation.
override
toString() → String
Returns the string encoded JSON representation for this class. This will remove all null values and empty collections from the returned string.

Operators

operator ==(Object other) → bool
The equality operator.
