Static Methods

createCylindricalProjectionTransform({required double radius, required double angle, double perspective = 0.001, Axis orientation = Axis.vertical}) → Matrix4

Create a transformation matrix which mimics the effects of tangentially wrapping the plane on which this transform is applied around a cylinder and then looking at the cylinder from a point outside the cylinder.

forceToPoint(Offset offset) → Matrix4

Returns a matrix that transforms every point to offset.

getAsScale(Matrix4 transform) → double?

Returns the given transform matrix as a double describing a uniform scale, if the matrix is nothing but a symmetric 2D scale transform.

getAsTranslation(Matrix4 transform) → Offset?

Returns the given transform matrix as an Offset, if the matrix is nothing but a 2D translation.

inverseTransformRect(Matrix4 transform, Rect rect) → Rect

Returns a rect that bounds the result of applying the inverse of the given matrix as a perspective transform to the given rect.

isIdentity(Matrix4 a) → bool

Whether the given matrix is the identity matrix.

matrixEquals(Matrix4? a, Matrix4? b) → bool

Returns true if the given matrices are exactly equal, and false otherwise. Null values are assumed to be the identity matrix.

transformPoint(Matrix4 transform, Offset point) → Offset

Applies the given matrix as a perspective transform to the given point.

transformRect(Matrix4 transform, Rect rect) → Rect

Returns a rect that bounds the result of applying the given matrix as a perspective transform to the given rect.
