-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!

-> Text Field “文本字段”
- 文本字段允许用户输入文本，无论是硬件键盘还是屏幕键盘。
- 每当用户更改字段中的文本时，文本字段就会调用Onchange的回调。
- 如果用户指示他们在字段中输入完成（例如，通过按软键盘上的按钮），则文本字段调用onSubmitted回调。

+> TextField 最常用的文本输入widget
+- 该 widget 作为文本输入框，可以接收用户以屏幕按键或者键盘输入的文本信息，该信息可以用于消息传递，搜索体验等

+- 已知用户输入的字段文本输入完毕时（例如，通过按软键盘上的按钮确认输入完毕），该widget会调用onSubmitted回调

- 默认情况下，文本字段具有在文本字段下方绘制分隔符的修饰。
- 您可以使用装饰属性来控制装饰，例如通过添加标签或图标。如果将装饰属性设置为空，则将完全删除装饰，包括装饰引入的额外填充，以节省标签的空间。
- 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。
- 若要将TeXFieldField集成到其他FieldFieldWrices窗体中，请考虑使用TeTFrimeField。""";

+const String _textFieldText2 = """### **进阶用法**
+> 实现稍微复杂点的效果，TextField 的输入以数字优先，为输入框做一些其他的效果，如提示文字，icon、标签文字等
 - 增加一个keyboardType属性，把keyboardType设置为 TextInputType.number ，让TextField获得焦点的时候弹出的键盘就变成了数字优先。
 - 新增decoration属性，设置相关属性，可以发现当我们的TextField获得焦点时，图标会自动变色，提示文字会自动上移。
- 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。
+- onChanged是输入框内每次文字变更触发的回调方法，onSubmitted是用户提交而触发的回调方法。
 - 每当用户改变输入框内的文字，都会在控制台输出现在的字符串.与onSubmitted用法相同。
