AffineMatrix class

An immutable affine matrix, a 3x3 column-major-order matrix in which the last row is always set to the identity values, i.e. 0 0 1.

Methods

multiplied(AffineMatrix other) → AffineMatrix
Creates a new affine matrix of this concatenated with other.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
rotated(double radians) → AffineMatrix
Creates a new affine matrix rotated by radians.
scaled(double x, [double? y]) → AffineMatrix
Creates a new affine matrix rotated by x and y.
scaleStrokeWidth(double? width) → double?
Calculates the scale for a stroke width based on the average of the x- and y-axis scales of this matrix.
toMatrix4() → Float64List
Creates a typed data representatino of this matrix suitable for use with package:vector_math_64 (and, by extension, Flutter/dart:ui).
toString() → String
A string representation of this object.
override
transformPoint(Point point) → Point
Maps point using the values of this matrix.
transformRect(Rect rect) → Rect
Maps rect using the values of this matrix.
translated(double x, double y) → AffineMatrix
Creates a new affine matrix, translated along the x and y axis.
xSkewed(double x) → AffineMatrix
Creates a new affine matrix, skewed along the x axis.
ySkewed(double y) → AffineMatrix
Creates a new affine matrix, skewed along the y axis.

Operators

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

Constants

identity → const AffineMatrix
The identity affine matrix.
