我在Flutter应用中使用了列表视图。我想在该列表中执行搜索。我不想在操作栏中搜索，而是要在列表本身中搜索。有人可以帮我吗？
这是我的ListTile代码：
new Column(
children: <Widget>[
new Padding(
padding: new EdgeInsets.all(8.0),
child: new TextField(
controller: searchController,
decoration: InputDecoration(
hintText: 'Search...',
contentPadding: EdgeInsets.fromLTRB(20.0, 15.0, 20.0, 15.0),
border: OutlineInputBorder(
borderRadius: BorderRadius.circular(32.0)),
),
),
This implements design part but i don't know how to implement logic
Here is my ListTile code
class BankDetailList extends StatelessWidget {
final List<BankDetail> bankdetail;
BankDetailList({Key key, this.bankdetail}) : super(key: key);
TextEditingController searchController = new TextEditingController();
String filter;
@override
Widget build(BuildContext context) {
//here is the List Tile code..
ListTile makeListTile(BankDetail bankDetail) => ListTile(
contentPadding:
EdgeInsets.symmetric(horizontal: 15.0, vertical: 10.0),
leading: Container(
padding: EdgeInsets.only(right: 12.0),
decoration: new BoxDecoration(
border: new Border(
right: new BorderSide(width: 1.0, color: Colors.white24))),
child: Icon(Icons.account_balance, color: Colors.white),
),
title: Text(
'${bankDetail.bank_name}',
style: TextStyle(color: Colors.white, fontWeight: FontWeight.bold,fontSize: 14.0),
),
// subtitle: Text("Intermediate", style: TextStyle(color:
Colors.white)),
subtitle: Row(
children: <Widget>[
Expanded(
flex: 0,
child: Container(
// tag: 'hero',
/*child: LinearProgressIndicator(

new Text('${bankDetail.city_name}',
style : TextStyle(color:Colors.white,fontSize: 10),
