封装组件
class MyBody extends StatelessWidget {
const MyBody({Key key}) : super(key: key);
@override
Widget build(BuildContext context) {
return Container(
child: Wrap(
children: [
RaisedButton(
onPressed: () {},
child: Text('第一季'),
textColor: Theme.of(context).accentColor,
elevation: 15.0,
),
],
),
);
}
}
1.先写好组件 然后准备抽出来封装RaisedButton
class MyButton extends StatelessWidget {
final String text;
const MyButton(this.text, {Key key}) : super(key: key);
@override
Widget build(BuildContext context) {
return RaisedButton(
onPressed: () {},
child: Text(this.text),
textColor: Theme.of(context).accentColor,
elevation: 15.0,
);
}
}
2.这样就可以封装一个组件了
