water_drop

Package Overview

Package selection guidance compiled from public package information, community data, and project usage.

The water_drop package enables developers to add realistic water drop effects on top of widgets in Flutter applications. It leverages custom shaders and animations to simulate the appearance of droplets forming, merging, and sliding across surfaces. Ideal for enhancing visual appeal in backgrounds, buttons, or interactive elements, it brings a dynamic, fluid aesthetic to UIs. The package is lightweight and integrates seamlessly with existing Flutter widgets, making it easy to implement without extensive configuration. It's particularly effective in apps that benefit from playful or naturalistic design themes.

How?

Just wrap your widget in WaterDrop and provide params:

Widget build(BuildContext context) {
  return WaterDrop(
    child: _StaticCard(color: Colors.green),
    params: [
      WaterDropParam(top: 50, height: 70, left: 100, width: 50),
      WaterDropParam(top: 10, height: 100, left: 280, width: 100),
      WaterDropParam(top: 155, height: 35, left: 135, width: 35),
      WaterDropParam(top: 135, height: 40, left: 250, width: 30),
      WaterDropParam(top: 20, height: 40, left: 20, width: 40),
      WaterDropParam(top: 140, height: 50, left: 15, width: 40),
      WaterDropParam(top: 20, height: 30, left: 200, width: 30),
      WaterDropParam(top: 120, height: 20, left: 360, width: 20),
    ],
  );
}

Or if you want a single drop, use WaterDrop.single:

@override
Widget build(BuildContext context) {
  return WaterDrop.single(
    top: 50,
    height: 70,
    left: 100,
    width: 50,
    child: _StaticCard(color: Colors.green),
  );
}
