DoughTransformer class abstract
The strategy for how to transform the Dough.child widget. Override this class to create your own dough-like squish effects. You can apply your custom DoughTransformer strategy using the Dough.transformer property.
See BasicDoughTransformer for an example on how to do this.
- Implementers
Constructors
- DoughTransformer()
- Creates a DoughTransformer.
Properties
- axis → Axis?
-
The axis on which to constrain any stretching.
no setter
- controller → DoughController
-
The controller for the associated Dough widget.
no setter
- delta → Vector2
-
The delta of the dough squish. This value is equivalent to
DoughController.delta, but is a vector instead of an offset.
no setter
- deltaAngle → double
-
The full-circle delta angle of the delta value, relative to the
Dough widgets up direction. This value ranges between 0 radians
and 2PI radians.
no setter
- hashCode → int
-
The hash code for this object.
no setterinherited
- origin → Vector2
-
The origin of the dough squish. This value is equivalent to
DoughController.origin, but is a vector instead of an offset.
no setter
- rawT → double
-
The unscaled animation time clamped between 0 and 1.
no setter
- recipe → DoughRecipeData
-
The contexual recipe applied to the associated Dough widget.
no setter
- runtimeType → Type
-
A representation of the runtime type of the object.
no setterinherited
- t → double
-
The scaled animation time, based on rawT, which has been transformed
by the DoughRecipeData.entryCurve or DoughRecipeData.exitCurve.
no setter
- target → Vector2
-
The target of the dough squish. This value is equivalent to
DoughController.target, but is a vector instead of an offset.
no setter
