在此link中,我们解决了设计浪潮quadraticBezierTo
,但这只是wavequadraticBezierTo浪潮的一半,我希望像此屏幕快照一样具有完整的设计:
现在我的问题是我们如何才能更改下面的代码以在其右侧进行另一半设计
class WaveClipperTwo extends CustomClipper<Path> {
bool reverse;
WaveClipperTwo({this.reverse = false});
final int _coefficient = 16;
double get _minStep => 1 / _coefficient;
double get _preCenter => _minStep * (_coefficient / 2 - 1);
double get _postCenter => _minStep * (_coefficient / 2 + 1);
double get _preEnd => _minStep * (_coefficient - 2);
@override
Path getClip(Size size) {
var path = Path();
path.moveTo(0.0, 0.0);
if(!reverse) {
path.lineTo(0.0, size.height - 20.0);
path.lineTo(size.width * _preCenter, size.height - 20.0);
path.cubicTo(size.width/2, size.height - 20.0, size.width/2, size.height - 40.0, size.width * _postCenter, size.height - 40.0);
path.lineTo(size.width * _preEnd, size.height - 40.0);
path.quadraticBezierTo(size.width, size.height - 40.0, size.width, size.height - 20.0);
path.lineTo(size.width, 0.0);
path.close();
}else{
path.lineTo(0.0, 20);
path.lineTo(size.width * _preCenter, 20.0);
path.cubicTo(size.width/2, 20.0, size.width/2, 40.0, size.width * _postCenter, 40.0);
path.lineTo(size.width * _preEnd, 40.0);
path.quadraticBezierTo(size.width, 40, size.width, 20.0);
path.lineTo(size.width, 0.0);
path.close();
}
return path;
}
@override
bool shouldReclip(CustomClipper<Path> oldClipper) => false;
}
