RSTransform class
A transform consisting of a translation, a rotation, and a uniform scale.
Used by Canvas.drawAtlas. This is a more efficient way to represent these simple transformations than a full matrix.
Constructors
 RSTransform(double scos, double ssin, double tx, double ty)
 Creates an RSTransform.
 RSTransform.fromComponents({required double rotation, required double scale, required double anchorX, required double anchorY, required double translateX, required double translateY})

Creates an RSTransform from its individual components.

Properties
 hashCode → int

The hash code for this object.
no setterinherited
 runtimeType → Type

A representation of the runtime type of the object.
no setterinherited
 scos → double

The cosine of the rotation multiplied by the scale factor.
no setter
 ssin → double

The sine of the rotation multiplied by that same scale factor.
no setter
 tx → double

The x coordinate of the translation, minus scos multiplied by the
xcoordinate of the rotation point, plus ssin multiplied by the
ycoordinate of the rotation point.
no setter
 ty → double

The y coordinate of the translation, minus ssin multiplied by the
xcoordinate of the rotation point, minus scos multiplied by the
ycoordinate of the rotation point.
