用 Flutter 在海边编织中秋代码诗篇，描绘月下码农的浪漫

在这个团圆的中秋佳节，让我们暂时抛开繁忙的工作，用代码在海边编织出一幅浪漫的诗篇，勾勒出月下码农的动人故事。

中秋月夜的代码诗歌

在 Flutter 的世界里，代码不再是冰冷的字符，而是可以幻化成各种图形和动画的魔法棒。我们可以用代码绘制出皓月当空、繁星点点，波涛汹涌的大海，以及翱翔于天际的大雁。

// Flutter 中绘制中秋月夜场景的代码

import 'package:flutter/material.dart';

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

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: '中秋月夜',
      home: MyHomePage(),
    );
  }
}

class MyHomePage extends StatefulWidget {
  @override
  _MyHomePageState createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('中秋月夜'),
      ),
      body: Center(
        child: CustomPaint(
          painter: MyPainter(),
        ),
      ),
    );
  }
}

class MyPainter extends CustomPainter {
  @override
  void paint(Canvas canvas, Size size) {
    // 绘制月亮
    Paint moonPaint = Paint()
      ..color = Colors.yellow
      ..strokeWidth = 10.0;
    canvas.drawCircle(Offset(size.width / 2, size.height / 2), 100.0, moonPaint);

    // 绘制星星
    Paint starPaint = Paint()
      ..color = Colors.white
      ..strokeWidth = 1.0;
    for (int i = 0; i < 100; i++) {
      double x = Random().nextDouble() * size.width;
      double y = Random().nextDouble() * size.height;
      canvas.drawCircle(Offset(x, y), 1.0, starPaint);
    }

    // 绘制大海
    Paint seaPaint = Paint()
      ..color = Colors.blue
      ..strokeWidth = 10.0;
    canvas.drawRect(Offset(0, size.height / 2), Size(size.width, size.height / 2), seaPaint);

    // 绘制大雁
    Paint goosePaint = Paint()
      ..color = Colors.black
      ..strokeWidth = 5.0;
    Path goosePath = Path();
    goosePath.moveTo(size.width / 2, size.height / 2);
    goosePath.lineTo(size.width / 2 + 100, size.height / 2 - 100);
    goosePath.lineTo(size.width / 2 + 200, size.height / 2);
    goosePath.lineTo(size.width / 2 + 100, size.height / 2 + 100);
    goosePath.close();
    canvas.drawPath(goosePath, goosePaint);
  }

  @override
  bool shouldRepaint(covariant CustomPainter oldDelegate) => true;
}

运行这段代码，一幅壮丽的中秋月夜图景便跃然屏上，皓月当空，繁星闪烁，波涛翻涌，大雁翱翔，交织成一曲动人的代码诗篇。

在海边码出浪漫

中秋月夜的海边，除了美景，更少不了浪漫。我们可以用代码描绘出我们心爱的 "Ta" 的肖像，用代码写下 "Ta" 的名字，用代码倾诉我们对 "Ta" 的爱慕。

// Flutter 中绘制 "Ta" 的肖像和名字的代码

import 'package:flutter/material.dart';

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

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: '中秋月夜',
      home: MyHomePage(),
    );
  }
}

class MyHomePage extends StatefulWidget {
  @override
  _MyHomePageState createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('中秋月夜'),
      ),
      body: Center(
        child: CustomPaint(
          painter: MyPainter(),
        ),
      ),
    );
  }
}

class MyPainter extends CustomPainter {
  @override
  void paint(Canvas canvas, Size size) {
    // 绘制 "Ta" 的肖像
    Paint portraitPaint = Paint()
      ..color = Colors.pink
      ..strokeWidth = 5.0;
    Path portraitPath = Path();
    portraitPath.moveTo(size.width / 2, size.height / 2);
    portraitPath.lineTo(size.width / 2 + 100, size.height / 2 - 100);
    portraitPath.lineTo(size.width / 2 + 200, size.height / 2);
    portraitPath.lineTo(size.width / 2 + 100, size.height / 2 + 100);
    portraitPath.close();
    canvas.drawPath(portraitPath, portraitPaint);

    // 绘制 "Ta" 的名字
    TextPainter namePainter = TextPainter(
      text: TextSpan(
        text: 'Ta',
        style: TextStyle(
          color: Colors.red,
          fontSize: 50.0,
        ),
      ),
      textDirection: TextDirection.ltr,
    );
    namePainter.layout();
    namePainter.paint(canvas, Offset(size.width / 2 - namePainter.width / 2, size.height / 2 + 100));

    // 绘制对 "Ta" 的爱慕之情
    TextPainter lovePainter = TextPainter(
      text: TextSpan(
        text: '我爱你',
        style: TextStyle(
          color: Colors.green,
          fontSize: 50.0,
        ),
      ),
      textDirection: TextDirection.ltr,
    );
    lovePainter.layout();
    lovePainter.paint(canvas, Offset(size.width / 2 - lovePainter.width / 2, size.height / 2 + 200));
  }

  @override
  bool shouldRepaint(covariant CustomPainter oldDelegate) => true;
}
