最佳答案
您需要使用 StateFulBuilder
将状态中的更改应用到模态:
showModalBottomSheet(
isScrollControlled: true,
context: context,
builder: (context) {
return StatefulBuilder( // this is new
builder: (BuildContext context, StateSetter setState) {
return Container(
height: 350,
child: Column(
children: <Widget>[
Container(
padding: EdgeInsets.only(
left: 10.0,
right: 10.0,
top: 20.0,
bottom: 15.0),
child: Text(
'Meritos',
style: TextStyle(
color: Colors.black,
fontSize: 24,
fontFamily: 'Jost',
fontWeight: FontWeight.bold),
),
),
Container(
height: 80,
padding:
EdgeInsets.only(left: 25.0, right: 25.0),
child: Column(
children: <Widget>[
CheckboxListTile(
title: Text('checkbox'),
onChanged: (bool value) {
setState(() {
_checked = value;
});
},
value: _checked,
)
],
)),
],
));
});
});
