How to create Wave Curves animation using Clipper Path in Flutter App
Introduction
Wave curves animation is a popular design trend in mobile applications, and Flutter provides an easy way to create such animations using the Clipper Path feature. In this article, we will explore how to create wave curves animation using Clipper Path in a Flutter app. We will discuss the benefits of using Clipper Path, the basic requirements, and provide a step-by-step guide on how to implement the animation.
What is Clipper Path
Clipper Path is a feature in Flutter that allows developers to create custom shapes and paths for their widgets. It provides a easy way to create complex shapes and animations by clipping the child widget to a specific path. Clipper Path is a powerful tool that can be used to create a wide range of animations and effects, including wave curves.
Creating Wave Curves Animation
To create a wave curves animation using Clipper Path, you will need to create a custom Clipper class that extends the ClipperRect class. This class will define the path of the wave curve. You will also need to create an animation controller to handle the animation.
“`dart
import ‘package:flutter/animation.dart’;
import ‘package:flutter/material.dart’;
class WaveClipper extends CustomClipper
@override
Path getClip(Size size) {
Path path = Path();
path.lineTo(0, size.height);
for (int i = 0; i < size.width; i++) {
double y = size.height – (i / size.width) * size.height;
double xOffset = i.toDouble();
path.lineTo(xOffset, y + sin(i / 10.0) * 20);
}
path.lineTo(size.width, size.height);
path.close();
return path;
}
@override
bool shouldReclip(WaveClipper oldClipper) => false;
}
“`
Using the WaveClipper class, you can create a wave curves animation by animating the path of the wave curve.
“`dart
AnimationController _animationController;
Animation
@override
void initState() {
super.initState();
_animationController = AnimationController(
vsync: this,
duration: const Duration(milliseconds: 2000),
);
animation = Tween
_animationController.repeat();
}
@override
Widget build(BuildContext context) {
return Scaffold(
body: ClipPath(
clipper: WaveClipper(),
child: AnimatedBuilder(
animation: _animation,
builder: (context, child) {
return Transform.translate(
offset: Offset(0, sin(_animation.value) * 20),
child: child,
);
},
child: Container(
height: 200,
color: Colors.blue,
),
),
),
);
}
“`
