matrix property

Matrix4 matrix

Fallback matrix for the web.

Since Canvas.drawAtlas is not supported on the web we also build a Matrix4 based on the transform and flip values.

Implementation

late final Matrix4 matrix =
    Matrix4(
        transform.scos,
        transform.ssin,
        0,
        0, //
        -transform.ssin,
        transform.scos,
        0,
        0, //
        0,
        0,
        0,
        0, //
        transform.tx,
        transform.ty,
        0,
        1, //
      )
      ..translateByDouble(source.width / 2, source.height / 2, 0.0, 1.0)
      ..rotateY(flip ? pi : 0)
      ..translateByDouble(-source.width / 2, -source.height / 2, 0.0, 1.0);
