Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text('Polygon Clip Example'),
),
body: Center(
child: FlutterClipPolygon(
sides: 12,
borderRadius: 5.0, // 默认为0.0度
rotate: 90.0, // 默认为0.0度
boxShadows: [
PolygonBoxShadow(color: Colors.red, elevation: 1.0),
PolygonBoxShadow(color: Colors.grey, elevation: 5.0)
],
child: Container(color: Colors.green),

import 'package:flutter/material.dart';
import 'package:flutter_polygon_clipper/flutter_polygon_clipper.dart';
class PolygonBorderExample extends StatelessWidget {
[@override](/user/override)
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text('Polygon Border Example'),
),
body: Center(
child: Container(
height: 100,
width: 100,
child: ElevatedButton(
style: ElevatedButton.styleFrom(
shape: FlutterPolygonBorder(
sides: 3,
borderRadius: 5.0, // 默认为0.0度
rotate: 30.0, // 默认为0.0度
side: BorderSide(color: Colors.red, width: 2.0), // 默认为无边框
