BouncyBall class

🏓 BouncyBall

random splashFactory and color on every tap--bouncy balls! A delightfully bouncy and position-mirroring reaction to user input on a piece of Material.

splashFactory

BouncyBall.splashFactory - bounce: "Bouncy Ball" An InteractiveInkFeatureFactory that produces 🏓 BouncyBalls as the ink splashes.

marbleFactory

BouncyBall.marbleFactory - bounce: "Toward Finger" An InteractiveInkFeatureFactory that produces 🔮 Glass BouncyBalls (marbles) as the ink splashes.

splashFactory2, splashFactory3, & splashFactory4

InteractiveInkFeatureFactorys that produce 🏓 BouncyBalls
as their ink splashes with varying bounce patterns.
BouncyBall.splashFactory2 - bounce: "Custom Ink" (Classic) BouncyBall.splashFactory3 - bounce: "Toward Finger" BouncyBall.splashFactory4 - bounce: "Toward Face"

BouncyBall.mold

An InteractiveInkFeatureFactory factory whose splashFactory
🪀 molds 🏓 BouncyBalls from custom rubber Paint.

A circular ink feature whose origin immediately moves from input touch point to an X- and Y-mirrored point opposite the touch point, growing to twice the size of its referenceBox.

This object is rarely created directly.
Instead of creating a 🏓 BouncyBall, consider using an InkResponse or InkWell widget, which uses gestures (such as tap and long-press) to trigger ink splashes.

When the Theme's ThemeData.splashFactory is BouncyBall.splashFactory, ink splashes will be 🏓 BouncyBalls.

See also:

  • InkRipple, which is a built-in ink splash feature that expands less aggressively than 🏓 BouncyBall.
  • InkWell, which uses gestures to trigger ink highlights and ink splashes in the parent Material.
  • 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
