Create a sizeable Widget with the specified gradient and all the
same properties as a standard Foil, but as its own standalone
AnimatedContainer with or without a child.
Properties
blendMode → BlendMode
The BlendMode utilized in painting this Foil's gradient
over its child .
final
box → Widget ?
Made non-null by Foil.sheet and then wraps child .
final
child → Widget
Wrap this child in Foil. Widget.
final
curve → Curve
The Curve for the animation of this Foil, either by
translation through pointer movements or by altering gradient .
final
duration → Duration
The Duration over which any changes to this Foil's gradient
will intrinsically animate. Default is 500ms.
final
gradient → Gradient ?
Customize the visual appearance of this Foil.
final
hashCode → int
The hash code for this object.
no setter inherited
isAgressive → bool
Control the method used to lerp the gradients.
final
isUnwrapped → bool
If isUnwrapped is true, this Foil's gradient will be inactive.
Default is false.
final
key → Key ?
Controls how one widget replaces another widget in the tree.
final inherited
onEnd → VoidCallback ?
Register a callback Function to perform when this Foil finishes
transitioning intrinsically from one gradient to another.
final
opacity → double
Override the alpha channels in this Foil's gradient by providing
an opacity value by which the gradient will be Gradient.scale d.
final
runtimeType → Type
A representation of the runtime type of the object.
no setter inherited
scalar → Scalar
A Scalar provides an opportunity to modify horizontal and vertical
pointer movement data independently before they translate to Foil
gradient "twinkling" transformation (offset/translation).
final
sheet → Sheet
Only applicable for a self-contained Foil.sheet . null unless constructing a Foil.sheet, where default is
new Sheet.
final
speed → Duration
How rapidly this Foil twinkles according to pointer movements.
final
unwrappedGradient → Gradient ?
Override the empty, transparent Gradient that this Foil transitions
to when isUnwrapped is made true.
final
useSensor → bool
Default is true. final
