Transform class

A widget that applies spatial transformations to its child.

In a terminal context, true rotation and scaling are not possible due to the character grid nature of terminals. This widget supports:

Transform.translate(
  offset: Offset(5, 2),
  child: Text('Shifted right 5, down 2'),
)

Inheritance

Constructors

Transform({int translateX = 0, int translateY = 0, bool flipH = false, bool flipV = false, Widget? child, Key? key}): Creates a transform with all options.
Transform.flipHorizontal({Widget? child, Key? key}): Creates a transform that flips content horizontally.
Transform.flipVertical({Widget? child, Key? key}): Creates a transform that flips content vertically.
Transform.translate({required Offset offset, Widget? child, Key? key}): Creates a transform with a translation offset.
