Usage #
Main Constructor
Mat3D can be created from optional Matrix4 and Rect.
Example:
main() {
final matrix4 = Matrix4.identity();
final rect = Offset.zero & const Size.square(100);
final mat3D = Mat3D(rect: rect, matrix: matrix4);
print(mat3D); // Mat3D[...](0, 0, 100, 100)
}

Raw Constructor
Mat3D can be created to tweak a Matrix4 value using a given rect.
Example:
main() {
final matrix4 = Matrix4.identity();
final rect = Offset.zero & const Size.square(100);
final mat3D = Mat3D.raw(rect: rect, matrix: matrix4);

/// changes to [mat3D] reflects on [matrix4]
print(mat3D); // Mat3D[...](0, 0, 100, 100)
}

Parse Constructor
Mat3D can be composed from a string source: result calling .toString()
on a Mat3D object.
Example:
main() {
final matrix4 = Matrix4.identity();
final rect = Offset.zero & const Size.square(100);
final mat3D = Mat3D(rect: rect, matrix: matrix4);
print(mat3D); // Mat3D[0, 1.0, 1.0...](0, 0, 100, 100)
final mat3D2 = Mat3D.parse('$mat3D');
print(mat3D2); // Mat3D[0, 1.0, 1.0...](0, 0, 100, 100)
}

Copy Constructor
Mat3D can be duplicated as redirection to another Mat3D object
Example:
main() {
final matrix4 = Matrix4.identity();
final rect = Offset.zero & const Size.square(100);
final mat3D = Mat3D.raw(rect: rect, matrix: matrix4);
print(mat3D); // Mat3D[0, 1.0, 1.0...](0, 0, 100, 100)
final mat3D2 = Mat3D.from(mat3D);

/// changes to [mat3D2] reflects on [mat3D]
print(mat3D2); // Mat3D[0, 1.0, 1.0...](0, 0, 100, 100)

padding: const EdgeInsets.all(8.0),
child: Center(
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: [
Transform(
transform: Mat3D().scale(1.5).forward(24).matrix,
child: const Text("Transformed"),
),
],
