Touch Ripple For Flutter

Customizable touch ripple for flutter widget

This Flutter package allows developer to customize most of the behaviors and animations, with excellent performance and a touch effect package that can be controlled externally.

In conclusion, using this package enables easy definition of flexible touch behaviors or touch animation.

How to apply ripple widget

Please referance to this code!

TouchRipple(
    onTap: () => print('Hello World!'),
    child: ... // <- this your widget!
),

Referance to the appropriate code to implement page movement with this code

TouchRipple(
    onTap: () {
        HapticFeedback.selectionClick();
        onTap?.call();
    },
    // or behavior
    tapBehavior: const TouchRippleBehavior(
        // "The spread animation must complete in order for the registered
        // event callback function to be called." which is equivalent to defining
        eventCallBackableMinPercent: 1,
    ),
);

Apply eventCallBackableMinPercent = 1

When defining the argument eventCallBackableMinPercent of the above [TouchRippleBehavior] to be 1, we can implement a behavior to move the page after the touch ripple effect is complete.
