This flutter package is customizable touch ripple effect widget for flutter, very flexible and performant, providing smooth touch effect animations.

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 refer to this code!

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

Refer to the appropriate code to implement page behavior 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,
    ),
);

How to task async? #

Please refer to this code!

If you need to implement page push through touch ripple, try changing the value of tapBehavior.eventCallBackableMinPercent.

// for async task.
TouchRipple<String>(
    onTapAsync: () async {
        return await Future.delayed(const Duration(milliseconds: 500), () {
            return "end";
        });
    },
    onTapAsyncStart: () => print("start"),
    onTapAsyncEnd: print,
    // ... skip
);

When 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.
