如何在没有 Flutter 脚手架的情况下在屏幕上获取简单文本?

How to get simple text on screen without Scafflod in Flutter?

我已经从 Scafflod 和按钮中清除了 Flutter 示例,并期待我得到相同的内容,但没有标题栏和按钮:

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

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return new MaterialApp(
      title: 'My app title',
      theme: new ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: new MyHomePage(),
    );
  }
}

class MyHomePage extends StatefulWidget {
  MyHomePage({Key key}) : super(key: key);


  @override
  _MyHomePageState createState() => new _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  int _counter = 0;

  @override
  Widget build(BuildContext context) {
    return new Center(
        child: new Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: <Widget>[
            new Text(
              'You have pushed the button this many times:',
            ),
            new Text(
              '$_counter',
              style: Theme.of(context).textTheme.display1,
            ),
          ],
        ),
      );

  }
}

不幸的是,我得到的东西不适合任何门:

这是什么?怎么变这么大?如何解决?

Scaffold 正在设置基本的 material 设计视觉布局结构,其中包括默认文本样式等。如果您出于任何原因不想使用 Scaffold,然后您可以使用 Theme.of(context) 从当前主题中应用相关的文本样式和颜色。例如:

Text(
  'You have pushed the button this many times:',
  style: Theme.of(context).primaryTextTheme.headline,
  textAlign: TextAlign.center,
),

您可以将文本包装在 "Material" 小部件中。此外,使用 "style:" 参数可以解决问题。

Material(
        color: Colors.transparent,
        child: Text(
            "Your Text Here",
            style: TextStyle(
              fontFamily: 'custom font', // remove this if don't have custom font
              fontSize: 20.0, // text size
              color: Colors.white, // text color
            ),
        ),
      )
Text(
  'Sign in / Sign up with',
  style: TextStyle(
    fontFamily: appFontFamily,
    fontSize: 20,
    decoration: TextDecoration.none,////set decoration to .none
    fontWeight: FontWeight.bold,
    color: defaultTitleColor,
  ),
)
