FractionalTranslationModifier class

Applies a translation transformation before painting its child.

The translation is expressed as a Offset scaled to the child's size. For example, an Offset with a dx of 0.25 will result in a horizontal translation of one quarter the width of the child.

Hit tests will only be detected inside the bounds of the FractionalTranslation, even if the contents are offset such that they overflow.

See also:

• Transform, which applies an arbitrary transform to its child widget at paint time.
• Transform.translate, which applies an absolute offset translation transformation instead of an offset scaled to the child.
• The catalog of layout widgets.
