Simple and easy to implement your markdown editor, it uses its own parser.

import 'package:cached_network_image/cached_network_image.dart';

void main() => runApp(const MyApp());

class MyApp extends StatelessWidget {
  const MyApp({Key? key}) : super(key: key);

  // This widget is the root of your application.
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        // This is the theme of your application.
        //
        // Try running your application with "flutter run". You'll see the
        // application has a blue toolbar. Then, without quitting the app, try
        // changing the primarySwatch below to Colors.green and then invoke
        // "hot reload" (press "r" in the console where you ran "flutter run",
        // or press Run > Flutter Hot Reload in IntelliJ). Notice that the
        // counter didn't reset back to zero; the application is not restarted.

  // This widget is the home page of your application. It is stateful, meaning
  // that it has a State object (defined below) that contains fields that affect
  // how it looks.

  // This class is the configuration for the state. It holds the values (in this
  // case the title) provided by the parent (in this case the App widget) and
  // used by the build method of the State. Fields in a Widget subclass are
  // always marked "final".

  final String title;

    // fast, so that you can just rebuild anything that needs updating rather
    // than having to individually change instances of widgets.

Markdown是一种可以使用普通文本编辑器编写的标记语言，通过简单的标记语法，它可以使普通文本内容具有一定的格式。更多介绍请参考[百度百科](https://baike.baidu.com/item/markdown/3245829?fr=aladdin)。

## 1.标题
行首加井号表示不同级别的标题(H1-H6),例如：# H1,## H2,### H3,#### H4(注意：#号后边应有英文空格)。
# 一级标题
## 二级标题
### 三级标题
#### 四级标题
##### 五级标题
###### 六级标题

## 2.文字效果

使用 * 将文字包围起来表示*斜体*，如：\\*斜体*。
使用 ** 将文字包围起来表示**粗体**，如：\\*\\*粗体**。
使用 ~~ 将文字包围起来表示~~删除线~~，如：\\~\\~删除线~~。

如果你想使一段话中部分文字高亮显示，来起到突出强调的作用，那么可以把它用\\`包围起来，`注意`这不是单引号，而是``Tab``上方，``数字1``左边的按键（注意使用``英文``输入法）。

##  3. 外链接

使用 \\[描述](链接地址) 为文字增加外链接。
这是去往 [旧时光网站](https://www.jiushig.com) 的链接。

## 4. 图片

使用 \\!\\[描述](图片链接地址) 插入图像，仅仅比链接前面多了一个!号。插入图片示例： 

![旧时光](https://oss.jiushig.com/oldtime/oldtime_wallpaper.png)

## 5. 列表

使用 *，+，- 表示无序列表。

- 无序列表项 一
- 无序列表项 二
- 无序列表项 三

行首加四个空格表示二级列表，以此类推。

+ 一级列表
    + 二级列表
        + 三级列表

## 6. 引用

行首使用 > 表示文字引用。

单个引用：

> 野火烧不尽，春风吹又生。野火烧不尽，春风吹又生。

当然，你也可以 使用多个>>

>我用了一个
>> 我用了两个

## 7. 片段

可以用 ``` 包裹一段文字，用来显示某一片段，例如显示如下代码片段：

```
\$(document).ready(function () {
    alert('RUNOOB');
});
```

## 8. 表格

          """,
          padding: const EdgeInsets.all(8),
          textStyle: const TextStyle(
            fontSize: 18,
            height: 1.8,
            color: Colors.black,
          ),
          onTapLink: (link) => _launchURL(link),
          imageWidget: (imageUrl) {
            debugPrint('imageUrl $imageUrl');
            return CachedNetworkImage(
              imageUrl: imageUrl,
              placeholder: (context, url) => const SizedBox(
                width: double.infinity,
                height: 300,
                child: Center(child: CircularProgressIndicator()),
              ),
              errorWidget: (context, url, error) => const Icon(Icons.error),
            );
          },
        ),
      ),
    );
  }
}
