InkRipple class Null safety

A visual reaction on a piece of Material to user input.

A circular ink feature whose origin starts at the input touch point and whose radius expands from 60% of the final radius. The splash origin animates to the center of its referenceBox.

This object is rarely created directly. Instead of creating an ink ripple, consider using an InkResponse or InkWell widget, which uses gestures (such as tap and long-press) to trigger ink splashes. This class is used when the Theme's ThemeData.splashFactory is InkRipple.splashFactory.

See also:

  • InkSplash, which is an ink splash feature that expands less aggressively than the ripple.
  • InkResponse, which uses gestures to trigger ink highlights and ink splashes in the parent Material.
  • InkWell, which is a rectangular InkResponse (the most common type of ink response).
  • Material, which is the widget on which the ink splash is painted.
  • InkHighlight, which is an ink feature that emphasizes a part of a Material.
