Flutter Matrix4 to rotate a Container by its center?

Posted by Andre Scott | Updated on October 7, 2020

I’ve found the answer and just made this package (to do all kinds of transformations, not only rotate by the center.

var height = 30;

var width = 30;

AnimatedContainer(

color: Colors.red,

width: width,

height: height,

transform:

Matrix4Transform()

.rotateDegrees(180, origin: Offset(width/2, height/2))

.matrix4,

);
