duration picker

Duration Picker for flutter #
Fork from flutter_duration_picker. https://github.com/cdharris/flutter_duration_picker
A little widget for picking durations. Heavily inspired from the Material Design time picker widget.

How to setup localization #
In order to support other languages, developers need to configure localization settings like the settings for the time picker. Example for english and korean:
class MyApp extends StatelessWidget {
const MyApp({Key? key}) : super(key: key);

@override
Widget build(BuildContext context) {
return MaterialApp(
title: 'Duration Picker Demo',
theme: ThemeData(
primarySwatch: Colors.blue,
),
localizationsDelegates: [
DurationPickerLocalizations.delegate,
GlobalMaterialLocalizations.delegate,
GlobalWidgetsLocalizations.delegate,
GlobalCupertinoLocalizations.delegate,
],
supportedLocales: [Locale('en'), Locale('ko')],
home: const MyHomePage(title: 'Duration Picker Demo'),
);
}
}

How to add more languages #

Add a localizations class in localizataions dir.

class DurationPickerLocalizationsKo extends DurationPickerLocalizations {
@override
String get baseUnitHour => '시간';

@override
String get baseUnitMillisecond => '밀리초';

...
}

The class should extend DurationPickerLocalizations. This makes it easy to write everything you should write.

Add the language code to the supportedLocales array in _DurationPickerLocalizationDelegate.

class _DurationPickerLocalizationDelegate
extends LocalizationsDelegate<DurationPickerLocalizations> {
const _DurationPickerLocalizationDelegate();

static const supportedLocales = ['en', 'ko'];

...

}

Return a DurationPickerLocalizations implementation as locale at load method in _DurationPickerLocalizationDelegate.

@override
Future<DurationPickerLocalizations> load(Locale locale) async {
switch (locale.languageCode) {
case 'ko':
return DurationPickerLocalizationsKo();
default:
return DurationPickerLocalizationsEn();
}

Example Usage: #
dependencies:
duration_picker: "^1.0.0"
copied to clipboard
import 'package:flutter/material.dart';
import 'package:duration_picker/duration_picker.dart';

void main() => runApp(MyApp());

class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
return MaterialApp(
title: 'Duration Picker Demo',
theme: ThemeData(
primarySwatch: Colors.blue,
),
home: MyHomePage(title: 'Duration Picker Demo'),
);
}
}

class MyHomePage extends StatefulWidget {
MyHomePage({Key key, this.title}) : super(key: key);

final String title;

@override
_MyHomePageState createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
Duration _duration = Duration(hours: 0, minutes: 0);
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text(widget.title),
),
body: Center(
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
Expanded(
child: DurationPicker(
duration: _duration,
onChange: (val) {
setState(() => _duration = val);
},
))
],
),
),
floatingActionButton: Builder(
builder: (BuildContext context) => FloatingActionButton(
onPressed: () async {
var resultingDuration = await showDurationPicker(
context: context,
initialTime: Duration(minutes: 30),
);
ScaffoldMessenger.of(context).showSnackBar(SnackBar(
content: Text('Chose duration: $resultingDuration')));
},
tooltip: 'Popup Duration Picker',
child: Icon(Icons.add),
)),
);
}
}
