InteractiveInkFeature class Null safety

An ink feature that displays a color "splash" in response to a user gesture that can be confirmed or canceled.

Subclasses call confirm when an input gesture is recognized. For example a press event might trigger an ink feature that's confirmed when the corresponding up event is seen.

Subclasses call cancel when an input gesture is aborted before it is recognized. For example a press event might trigger an ink feature that's canceled when the pointer is dragged out of the reference box.

The InkWell and InkResponse widgets generate instances of this class.
