Flutter多边形按钮插件polygon_button的使用

Flutter多边形按钮插件polygon_button的使用

一个简单的Flutter插件，用于创建具有多边形形状的按钮。可以轻松地将多边形按钮集成到您的Flutter应用程序中。

安装

在pubspec.yaml文件中添加以下依赖：

dependencies:
  polygon_button: 1.0.0

然后运行flutter pub get以安装该插件。

使用

以下是如何使用polygon_button插件的基本示例：

import 'package:flutter/material.dart';
import 'package:polygon_button/polygon_button.dart';

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

class MyApp extends StatelessWidget {
  const MyApp({super.key});

  // 这个小部件是你的应用的根。
  [@override](/user/override)
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Polygon Button Demo',
      theme: ThemeData(
        colorScheme: ColorScheme.fromSeed(seedColor: Colors.deepPurple),
        useMaterial3: true,
      ),
      home: const MyHomePage(title: 'Polygon Button Demo Page'),
    );
  }
}

class MyHomePage extends StatefulWidget {
  const MyHomePage({super.key, required this.title});
  final String title;

  [@override](/user/override)
  State<MyHomePage> createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  List<int> counters = [0, 0, 0, 0];

  Function() _incrementCounter(int i) {
    return () {
      setState(() {
        counters[i]++;
      });
    };
  }

  [@override](/user/override)
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        backgroundColor: Theme.of(context).colorScheme.inversePrimary,
        title: Text(widget.title),
      ),
      body: Center(
        child: Stack(
          children: [
            Positioned(
              left: 10,
              top: 10,
              child: PolygonButton(
                onPressed: _incrementCounter(0),
                vertices: const [
                  Offset(0, 0),
                  Offset(50, 200),
                  Offset(300, 100)
                ],
                child: Text("Clicked ${counters[0]} times"),
              ),
            ),
            Positioned(
              left: 300,
              top: 20,
              child: PolygonButton(
                onPressed: _incrementCounter(1),
                vertices: const [
                  Offset(0, 0),
                  Offset(50, 200),
                  Offset(300, 100)
                ],
                child: Text("Clicked ${counters[1]} times"),
              ),
            ),
            Positioned(
              left: 100,
              top: 200,
              child: PolygonButton(
                onPressed: _incrementCounter(2),
                vertices: const [
                  Offset(100, 0),
                  Offset(100, 200),
                  Offset(0, 100),
                  Offset(40, 100)
                ],
                child: Text("Clicked ${counters[2]} times"),
              ),
            ),
            Positioned(
              left: 300,
              top: 200,
              child: PolygonButton(
                onPressed: _incrementCounter(3),
                vertices: const [

                makeConvex: true,
                child: Text("Clicked ${counters[3]} times"),
