Getting started

• Add this to your pubspec.yaml

  dependencies:
    liquid_container: ^1.0.4
  

• Get the package from Pub:

  flutter packages get
  

• Import it in your file

  import 'package:liquid_container/liquid_container.dart';
  

Usage

• Create options

  final optionsParam = Options(
    layers: [
      LayerModel(
        points: [],
        viscosity: 0.9,
        touchForce: 30,
        forceLimit: 15,
        color: const Color(0xFF00FF00),
      ),
      LayerModel(
        points: [],
        viscosity: 0.9,
        touchForce: 50,
        forceLimit: 10,
        color: const Color(0xFFFF0000),
      ),
    ],
    gap: 30,
    noise: 30,
    forceFactorBuild: 10,
    forceFactorOnTap: 150,
  );

• Add BoxDecoration to customize the container shape (optional)

  BoxDecoration _borderForm() {
    return const BoxDecoration(
        borderRadius: BorderRadius.only(
      topLeft: Radius.circular(40),
      topRight: Radius.circular(80),
      bottomLeft: Radius.circular(150),
      bottomRight: Radius.circular(20),
    ));
  }

• Use the pretty hover button

  Widget _buildLiquidButton() {
    return LiquidContainer(
      onTap: () {
        // same code
      },
      optionsParam: optionsParam,
      boxDecorationLabel: _borderForm(),
      child: _buildSomeChild(),
    );
  }

Full example

import 'package:flutter/material.dart';

void main() {
  runApp(const LiquidApp());
}

class LiquidApp extends StatelessWidget {
  static const title = 'Liquid Container';

  const LiquidApp({
    super. key,
