ExtendedTransformTranslate class
ExtendedTransformTranslate is a stateful widget that allows you to apply a translation transform to a child widget. This widget provides a method to update the translation offset, allowing you to only rebuild the transform without affecting the child widget.
This is useful for scenarios where you need to animate or dynamically change the position of a widget without triggering a rebuild of the widget's children.
The initOffset parameter sets the initial translation offset, and the child parameter is the widget to be translated.
