我有以下JavaScript代码here is the full implementation。
class StackOver extends StatefulWidget {
@override
_StackOverState createState() => _StackOverState();
}
class _StackOverState extends State<StackOver>
with SingleTickerProviderStateMixin {
TabController _tabController;
@override
void initState() {
_tabController = TabController(length: 2, vsync: this);
super.initState();
}
@override
void dispose() {
super.dispose();
_tabController.dispose();
}
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text(
'Tab bar',
),
),
body: Padding(
padding: const EdgeInsets.all(8.0),
child: Column(
children: [
// give the tab bar a height [can change hheight to preferred height]
Container(
height: 45,
decoration: BoxDecoration(
color: Colors.grey[300],
borderRadius: BorderRadius.circular(
25.0,
),
),
child: TabBar(
controller: _tabController,
// give the indicator a decoration (color and border radius)
indicator: BoxDecoration(
borderRadius: BorderRadius.circular(
25.0,
),
color: Colors.green,
),
labelColor: Colors.white,
unselectedLabelColor: Colors.black,
tabs: [
// first tab [you can add an icon using the icon property]
Tab(
text: 'Place Bid',
),
// second tab [you can add an icon using the icon property]
Tab(
text: 'Buy Now',
),
],
),
),
// tab bar view here
Expanded(
child: TabBarView(
controller: _tabController,
children: [
// first tab bar view widget
Center(
child: Text(
'Place Bid',
style: TextStyle(
fontSize: 25,
fontWeight: FontWeight.w600,
),
),
),
// second tab bar view widget
Center(
child: Text(
'Buy Now',
style: TextStyle(
fontSize: 25,
fontWeight: FontWeight.w600,
),
),
),
],
),
),
],
),
),
);
}
}
如何用打字稿扩展Material-ui组件?
答案 0 :(得分:0)
我找到了可能的答案here
interface IRegularButtonProps extends WithStyles<typeof buttonStyle> {
color?: string;
round?: boolean;
...
}
const RegularButton = React.forwardRef(
(props: IRegularButtonProps, ref: any) => {
...
}
基本上,它将默认按钮props扩展为创建重载的props。 我不知道这是否是正确的方法,但这是我找到的最佳解决方案。
