Hello @mankeomorakort ,
Thank you very much for your proposal, I think it makes perfect sense.
I proposed an implementation as part of PR #11 :
import 'package:flutter/material.dart';
import 'package:searchable_dropdown/searchable_dropdown.dart';
class OilProducer {
String name;
int id;
OilProducer({this.name, this.id});
OilProducer.fromJson(json) {
name = json['name'];
id = json['id'];
}
Map<String, dynamic> toJson() {
final Map<String, dynamic> data = new Map<String, dynamic>();
data['name'] = this.name;
data['id'] = this.id;
return data;
}
String toString(){
return(name);
}
}
void main() => runApp(MyApp());
class MyApp extends StatefulWidget {
@override
_MyAppState createState() => _MyAppState();
}
class _MyAppState extends State<MyApp> {
List<OilProducer> oilProducers = [];
OilProducer selectedOilProducer;
@override
void initState() {
oilProducers.add(OilProducer(name:"Petronas",id:1));
oilProducers.add(OilProducer(name:"Petrobras",id:2));
oilProducers.add(OilProducer(name:"Trebol",id:3));
oilProducers.add(OilProducer(name:"AGIP",id:4));
super.initState();
}
_dropSearch() {
return new SearchableDropdown<OilProducer>(
isCaseSensitiveSearch: true,
items: oilProducers.map((fab) {
return DropdownMenuItem<OilProducer>(
child: new Text(fab.name),
value: fab,
);
}).toList(),
value: selectedOilProducer,
hint: new Text('Select One'),
searchHint: new Text(
'Select One',
style: new TextStyle(fontSize: 20),
),
onChanged: (OilProducer value) {
setState(() {
this.selectedOilProducer = value;
});
},
displayClearButton: true,
validator: (value){return(value==null?"Mandatory":null);},
label: (value){return("Oil producer");},
keyboardType: TextInputType.text,
searchFn: (String keyword, List<DropdownMenuItem<OilProducer>> items) {
List<int> ret = List<int>();
if (keyword != null && items != null) {
keyword.split(" ").forEach((k) {
int i = 0;
items.forEach((item) {
if (keyword.isEmpty || (k.isNotEmpty &&
(item.value.name.toLowerCase().contains(k.toLowerCase()) ||
item.value.id.toString().contains(k)))) {
ret.add(i);
}
i++;
});
});
}
if(keyword.isEmpty){
ret = Iterable<int>.generate(items.length).toList();
}
return (ret);
},
);
}
@override
Widget build(BuildContext context) {
return MaterialApp(
home: Scaffold(
appBar: AppBar(
title: const Text('Searchable Dropdown Demo'),
),
resizeToAvoidBottomPadding: false,
body: Padding(
padding: const EdgeInsets.all(15.0),
child: Column(
crossAxisAlignment: CrossAxisAlignment.center,
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
_dropSearch(),
],
),
),
),
);
}
}
