Markdown allows you to easily include formatted text, images, and even formatted Dart code in your app.
## Styling
Style text as _italic_, __bold__, or `inline code`.
- Use bulleted lists
- To better clarify
- Your points
## Links
You can use [hyperlinks](hyperlink) in markdown
## Images
You can include images:
![Flutter logo](https://flutter.io/images/flutter-mark-square-100.png#100x100)
## Markdown widget
This is an example of how to create your own Markdown widget:
new Markdown(data: 'Hello _world_!');
## Code blocks
Formatted Dart code looks really pretty too:
```
void main() {
runApp(new MaterialApp(
home: new Scaffold(
body: new Markdown(data: markdownData)
)
));
}
```
Enjoy!

- 在对话框中使用Flat button或与其他内容内联但使用填充从该内容偏移以便按钮的存在是显而易见的。
- Flat buttons 故意不具有可见边框,因此必须依赖于它们相对于其他内容的位置以用于上下文。

> FloatingAction Button “浮动动作按钮”
- FloatingActionButton 按钮是一个圆形图标按钮悬停在内容上以提升应用程序中的主要操作。浮动操作按钮最常用于Scaffold.floatingActionButton字段中。。
- 每个屏幕最多使用一个浮动操作按钮。浮动操作按钮应用于积极操作,例如“创建”,“共享”或“导航”。
- 一般用来处理界面中最常用,最基础的用户动作。它一般出现在屏幕内容的前面,通常是一个圆形,中间有一个图标。 FAB有三种类型regular, mini, and extended。不要强行使用FAB只有当使用场景符合FAB功能的时候使用才最为恰当

### **简介**
> 按下时显示菜单
- 当菜单因为选择了项目而被解除时调用onSelected。传递给onSelected的值是所选菜单项的值。
- 可以提供 `child` 或 `icon` 中的一个,但不是能同时设置两者。如果提供了 `icon` ,则 `PopupMenuButton` 的行为类似于 `IconButton`。
- 如果两者都为null则创建一个标准 overflow icon取决于平台

- 在枚举值之间进行选择并_selection根据选择设置字段。

### **进阶用法**
> 此示例尝试调整所有属性,展示出效果
- 默认选择第二个。
- 再次打开,`PopupMenuItem` 保留上次的选择结果。

- 如果装饰是非null这是默认的文本字段需要它的祖先之一是一个材质widget。当文本字段被敲击时墨水溅到材料上的油漆被触发。

- onChanged是每次输入框内每次文字变更触发的回调onSubmitted是用户提交而触发的回调。

### **简介**
> 用来选择范围性的数据
slider 用来选择连续性的或者非连续性的数据. 默认是在一段最大值最小值间做任意值的选择. 如果你想选择间隔性的值, 例如0.0到50.0间,选择10, 15,...50.0这样的值, 给divisions设定一个非空的整数5,, 去分割区间范围.
### **基本用法**
关于slider有以下的术语:
* **thumb** 滑块 用户可以水平拖拽移动的区域
* **track** 滑轨 thumb 可以滑动的线条区域
* **value indicator** 值指示器 当用户拖拽thumb的时候. 显示用户当前所选的属性值
* **active** 选中区
* **inactive** 非选中区
如果**onChanged**属性为空或者**min** .. **max**给出的范围 为空例如如果min等于max则将禁用滑块。
滑块小部件本身不保持任何状态State。相反当滑块状态发生变化时窗口小部件会调用 **onChanged** 回调。大多数使用滑块的小部件将侦听 **onChanged** 回调并使用新值重建滑块以更新滑块的视觉外观。要知道值何时开始更改,或何时更改,请设置可选回调**onChangeStart**或**onChangeEnd**。
默认情况下滑块将尽可能宽垂直居中。当给定无限制约束时它将尝试使轨道宽144像素每边有边距并垂直收缩。
### **基本实例**

const contentB = '''
### **高级用法**
> 自定义Slider 样式
如果当前Slider样式 无法满足需求, 可以通过 ** SliderTheme ** 定制复杂样式

- activeThumbImage [**ImageProvider**] 当按钮状态处于激活态时, 按钮的背景图像
