import 'package:easy_autocomplete/easy_autocomplete.dart';
import 'package:flutter/material.dart';

void main() {
runApp(MyApp());
}

class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
return MaterialApp(
title: 'Example',
theme: ThemeData(
primarySwatch: Colors.blue,
),
home: SafeArea(
child: Scaffold(
appBar: AppBar(
title: Text('Example')
),
body: Container(
padding: EdgeInsets.all(10),
alignment: Alignment.center,
child: EasyAutocomplete(
suggestions: ['Afeganistan', 'Albania', 'Algeria', 'Australia', 'Brazil', 'German', 'Madagascar', 'Mozambique', 'Portugal', 'Zambia'],
onChanged: (value) => print('onChanged value: $value'),
onSubmitted: (value) => print('onSubmitted value: $value')
)
)
)
)
);
}
}
copied to clipboard
Example with customized style #
You can customize other aspects of the autocomplete widget such as the suggestions text style, background color and others as shown in example below:
import 'package:easy_autocomplete/easy_autocomplete.dart';
import 'package:flutter/material.dart';

void main() {
runApp(MyApp());
}

class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
return MaterialApp(
title: 'Example',
theme: ThemeData(
primarySwatch: Colors.blue,
),
home: SafeArea(
child: Scaffold(
appBar: AppBar(
title: Text('Example')
),
body: Container(
padding: EdgeInsets.all(10),
alignment: Alignment.center,
child: EasyAutocomplete(
suggestions: ['Afeganistan', 'Albania', 'Algeria', 'Australia', 'Brazil', 'German', 'Madagascar', 'Mozambique', 'Portugal', 'Zambia'],
cursorColor: Colors.purple,
decoration: InputDecoration(
contentPadding: EdgeInsets.symmetric(vertical: 0, horizontal: 10),
focusedBorder: OutlineInputBorder(
borderRadius: BorderRadius.circular(5),
borderSide: BorderSide(
color: Colors.purple,
style: BorderStyle.solid
)
),
enabledBorder: OutlineInputBorder(
borderRadius: BorderRadius.circular(5),
borderSide: BorderSide(
color: Colors.purple,
style: BorderStyle.solid
)
)
),
suggestionBuilder: (data) {
return Container(
margin: EdgeInsets.all(1),
padding: EdgeInsets.all(5),
decoration: BoxDecoration(
color: Colors.purple,
borderRadius: BorderRadius.circular(5)
),
child: Text(
data,
style: TextStyle(
color: Colors.white
)
)
);
}
onChanged: (value) => print(value)
)
)
)
)
);
}
}

The above example will generate something like below preview:

Example with asynchronous data fetch #
To create a autocomplete field that fetches data asynchronously you will need to use asyncSuggestions instead of suggestions
import 'package:easy_autocomplete/easy_autocomplete.dart';
import 'package:flutter/material.dart';

void main() {
runApp(MyApp());
}

class MyApp extends StatelessWidget {
Future<List<String>> _fetchSuggestions(String searchValue) async {
await Future.delayed(Duration(milliseconds: 750));
List<String> _suggestions = ['Afeganistan', 'Albania', 'Algeria', 'Australia', 'Brazil', 'German', 'Madagascar', 'Mozambique', 'Portugal', 'Zambia'];
List<String> _filteredSuggestions = _suggestions.where((element) {
return element.toLowerCase().contains(searchValue.toLowerCase());
}).toList();
return _filteredSuggestions;
}

@override
Widget build(BuildContext context) {
return MaterialApp(
title: 'Example',
theme: ThemeData(
primarySwatch: Colors.blue,
),
home: SafeArea(
child: Scaffold(
appBar: AppBar(
title: Text('Example')
),
body: Container(
padding: EdgeInsets.all(10),
alignment: Alignment.center,
child: EasyAutocomplete(
asyncSuggestions: (searchValue) async => _fetchSuggestions(searchValue),
onChanged: (value) => print(value)
)
)
)
)
);
}
}
