A facade widget that hide the complexity of setting animation in Flutter

Properties

animatorKey → AnimatorKey<T>?
The name of your Animator widget. Many widgets can have the same name.
final
builder → Widget Function(BuildContext context, AnimatorState<T> animatorState, Widget? child)
The build strategy currently used for one Tween. Animator widget rebuilds itself every time the animation changes value.
final
child → Widget?
Widget that you do not want to animate. It is the static part of the animated Widget.
final
curve → Curve?
An easing curve, i.e. a mapping of the unit interval to the unit interval.
final
customListener → (void Function(AnimatorState<T>)?)
Function to be called every time the animation value changes.
final
cycles → int?
The number of forward and backward periods the animation performs before stopping
final
duration → Duration
A span of time, such as 27 days, 4 hours, 12 minutes, and 3 seconds
final
endAnimationListener → (void Function(AnimatorState<T>)?)
VoidCallback to be called when animation is finished.
final
hashCode → int
The hash code for this object.
no setterinherited
key → Key?
Controls how one widget replaces another widget in the tree.
finalinherited
repeats → int?
The number of forward periods the animation performs before stopping
final
resetAnimationOnRebuild → bool
Whether the animation settings are reset when Animator widget is rebuilt. The default value is false.
final
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
statusListener → (void Function(AnimationStatus, AnimatorState<T>)?)
Function to be called every time the status of the animation changes.
final
triggerOnInit → bool?
Whether to start the animation when the Animator widget is inserted into the tree.
final
tween → Tween<T>?
A linear interpolation between a beginning and ending value.
final
tweenMap → Map<String, Tween>?
A linear interpolation between a beginning and ending value.
final

Methods

createElement() → StatefulElement
Creates a StatefulElement to manage this widget's location in the tree.
inherited
createState() → _AnimatorState<T>
Creates the mutable state for this widget at a given location in the tree.
override
debugDescribeChildren() → List<DiagnosticsNode>
Returns a list of DiagnosticsNode objects describing this node's children.
inherited
debugFillProperties(DiagnosticPropertiesBuilder properties) → void
Add additional properties associated with the node.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
toDiagnosticsNode({String? name, DiagnosticsTreeStyle? style}) → DiagnosticsNode
Returns a debug representation of the object that is used by debugging tools and by DiagnosticsNode.toStringDeep.
inherited
toString({DiagnosticLevel minLevel = DiagnosticLevel.info}) → String
A string representation of this object.
inherited
toStringDeep({String prefixLineOne = '', String? prefixOtherLines, DiagnosticLevel minLevel = DiagnosticLevel.debug}) → String
Returns a string representation of this node and its descendants.
inherited
toStringShallow({String joiner = ', ', DiagnosticLevel minLevel = DiagnosticLevel.debug}) → String
Returns a one-line detailed description of the object.
inherited
toStringShort() → String
A short, textual description of this widget.
