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.

Constructors

AffineMatrix.new(double a, double b, double c, double d, double e, double f, [double? m4_10])

Creates an immutable affine matrix. To work with the identity matrix, use the identity property.

const

final

d → double

The 1,1 position of the matrix.

final

e → double

The 2,0 position of the matrix.

final

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.
