我连续有两个容器,我要做的是,当我单击第一个容器时,它会更改其颜色以及第二个容器
即-当我单击第一个容器时,它看起来像已选中,另一个已取消选择,并且与第二个容器相同。
反正有这样做吗?
GestureDetector(
onTap: () {
print('its getting pressed');
},
child: Row(
crossAxisAlignment: CrossAxisAlignment.center,
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
Expanded(
child: Container(
height: screenHeight * 0.057,
width: double.infinity,
color: greyf1,
child: Center(
child: Text(
'Borrower',
style: hintTextTextStyle,
),
),
),
),
SizedBox(
width: 10,
),
Expanded(
child: Container(
height: screenHeight * 0.057,
width: double.infinity,
color: greyf1,
child: Padding(
padding: const EdgeInsets.only(left: 15),
child: Center(
child: Text(
'Lender',
style: hintTextTextStyle,
),
),
),
),
),
],
),
),

您可以尝试以下方法。这将使用selected
属性来确定哪个容器应为蓝色。
尚未测试代码
class _TestState extends State<Test> {
String selected = "first";
@override
Widget build(BuildContext context) {
return Column(
children: <Widget>[
GestureDetector(
onTap: () {
setState(() {
selected = 'first';
});
},
child: Container(
height: 200,
width: 200,
color: selected == 'first' ? Colors.blue : Colors.transparent,
child: Text("First"),
),
),
GestureDetector(
onTap: () {
setState(() {
selected = 'second';
});
},
child: Container(
height: 200,
width: 200,
color: selected == 'second' ? Colors.blue : Colors.transparent,
child: Text("Second"),
),
),
],
);
}
}
