Flutter ClipPath Examples

ClipPath in Flutter is a widget that clips its child using a path. We use ClipPath to make the child widget appear masked in our designed shape.

If you want to animate ClipPath, read this post.

Wave

ClipPath(
                clipper: WaveShape(),
                child: Container(
                  width: MediaQuery.of(context).size.width,
                  height: 160,
                  color: Colors.lightGreen,
                ),
              )

class WaveShape extends CustomClipper<Path> {
  @override
  getClip(Size size) {
    double height = size.height;
    double width = size.width;

    var p = Path();
    p.lineTo(0, 0);
    p.cubicTo(width * 1 / 2, 0, width * 2 / 4, height, width, height);
    p.lineTo(width, 0);
    p.close();

    return p;
  }

  @override
  bool shouldReclip(CustomClipper oldClipper) => true;
}

Wave

ClipPath(
          clipper: WaveClip(),
          child: Container(
            color: Colors.blue,
            child: Column(
              mainAxisAlignment: MainAxisAlignment.center,
              children: <Widget>[
                title,
              ],
            )

class WaveClip extends CustomClipper<Path> {
  @override
  Path getClip(Size size) {
    Path path = new Path();
    final lowPoint = size.height - 20;
    final highPoint = size.height - 40;

    path.lineTo(0, size.height);
    path.quadraticBezierTo(
        size.width / 4, highPoint, size.width / 2, lowPoint);
    path.quadraticBezierTo(
        3 / 4 * size.width, size.height, size.width, lowPoint);
    path.lineTo(size.width, 0);

    return path;
  }

  @override
  bool shouldReclip(CustomClipper<Path> oldClipper) {
    return false;
  }
}

Round bottom

ClipPath(
            clipper: RoundShape(),
            child: Container(
              height: 40,
              color: Colors.lightGreen,
            ),
          )

class RoundShape extends CustomClipper<Path> {
  @override
  getClip(Size size) {
    double height = size.height;
    double width = size.width;
    double curveHeight = size.height / 2;

    var p = Path();
    p.lineTo(0, height - curveHeight);
    p.quadraticBezierTo(width / 2, height, width, height - curveHeight);
    p.lineTo(width, 0);
    p.close();

    return p;
  }

  @override
  bool shouldReclip(CustomClipper oldClipper) => true;
}
