Constructors
- Transform({required Matrix4 transform, PdfPoint? origin, Alignment? alignment, bool adjustLayout = false, bool unconstrained = false, Widget? child})
- Transform.rotate({required double angle, PdfPoint? origin, Alignment? alignment = Alignment.center, Widget? child})
- Creates a widget that transforms its child using a rotation around the center.
- Transform.rotateBox({required double angle, Widget? child, bool unconstrained = false})
- Creates a widget that transforms its child using a rotation around the center and relayout the bounding box.
- Transform.scale({required double scale, PdfPoint? origin, Alignment? alignment = Alignment.center, Widget? child})
- Creates a widget that scales its child uniformly.
- Transform.translate({required PdfPoint offset, Widget? child})
- Creates a widget that transforms its child using a translation.
