Crinkle class

Provide animation to a piece of Foil by wrapping it in a Roll with a specified Crinkle.

A new Roll() by default is not animated―because its Crinkle is smooth―but a new Crinkle is animated by default.

See each parameter for more information.

Properties

hashCode → int
The hash code for this object.
no setterinherited
isAnimated → bool
A new Roll() by default is not animated―because its Crinkle is smooth―but a new Crinkle is animated by default.
final
max → double
The bounds of this Crinkle's animation. Default drives -2..2.
final
min → double
The bounds of this Crinkle's animation. Default drives -2..2.
final
period → Duration
The Duration of time for one animation pass in a single direction. If shouldReverse, this period will pass twice before the animation returns to its original min value.
final
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
scalar → Scalar
A final multiplier to scale the gradient translation, independently configurable for either Scalar.horizontal or Scalar.vertical axis. The default is Scalar.identity which makes no impact.
final
shouldReverse → bool
A new Roll() by default is not animated―because its Crinkle is smooth―but a new Crinkle is animated by default.
final
transform → TransformGradient?
Register a callback that accepts the x and y that are provided
from Roll.rollListenable * Crinkle.scalar, where that
animation value ranges from min to max over period.

Methods

copyWith({bool? isAnimated, bool? shouldReverse, double? min, double? max, Scalar? scalar, Duration? period, TransformGradient? transform}) → Crinkle
📋 Returns a copy of this Crinkle with the provided optional parameters overriding those of this.
debugFillProperties(DiagnosticPropertiesBuilder properties) → void
Add additional properties associated with the node.
override
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
toStringShort() → String
A brief description of this object, usually just the runtimeType and the hashCode.

Operators

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

Constants

crawling → const Crinkle
An incredibly slow Crinkle.
loop → const Crinkle
Testing.
smooth → const Crinkle
This Crinkle is actually smooth...
this constant initializes isAnimated to false.
twinkling → const Crinkle
A gently animated Crinkle.
vivacious → const Crinkle
An extremely animated Crinkle.
