Flutter自定义形状绘制插件shape_maker的使用

Shape Maker

Shape Maker 是一个用于Flutter的可定制且易于使用的形状绘制库。它允许你快速轻松地添加不同种类的形状，如三角形、六边形和八边形。此外，它还提供了颜色、大小等自定义选项，可以帮助开发者直接在Container、Text、Button或Image等小部件中作为背景使用。

该库完全使用Dart编写。

开始使用

在你的Flutter项目的pubspec.yaml文件中，添加以下依赖：

dependencies:
  ...
  shape_maker: ^0.0.1

在你的Dart文件中添加以下导入：

import 'package:shape_maker/shape_maker.dart';

使用示例

以下是一个完整的示例项目，展示了如何使用Shape Maker库来创建一个六边形形状，并将其作为页面的中心元素显示。

完整示例代码

import 'package:flutter/material.dart';
import 'package:shape_maker/shape_maker.dart'; // 导入Shape Maker库

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

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

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Shape Maker Example', // 应用标题
      theme: ThemeData(
        primarySwatch: Colors.blue, // 主题颜色
      ),
      home: const MyHomePage(title: 'Shape Maker Example'), // 主页
    );
  }
}

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

  final String title;

  @override
  State<MyHomePage> createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: Center(
        child: ShapeMaker(
          shapeType: ShapeType.hexagon, // 设置形状类型为六边形
          bgColor: Colors.blue, // 设置背景颜色为蓝色
        ),
      ),
    );
  }
}

详细说明

• ShapeMaker：这是Shape Maker库的核心小部件，用于绘制自定义形状。

  • shapeType：指定要绘制的形状类型，例如ShapeType.hexagon表示六边形。
  • bgColor：设置形状的背景颜色。

• ShapeType：这是一个枚举类型，包含多种形状选项，如hexagon（六边形）、triangle（三角形）等。
