I am trying to format the selected time from time-picker in my flutter app. I don't know why but this is proving to be more difficult than it should be. The end result I am trying to achieve is hour:minuets or 5:00pm. This will display in a box container after user has picked the time from the time-picker widget. I have a method called 'timeFormater()' which will format the selcted time but i'm getting the error 'flutter: type 'TimeOfDay' is not a subtype of type 'Widget' when I run my code. Is there an easier way/method in flutter for formatting TimeOfDay()?
My Code:
import 'package:flutter/material.dart';
import 'package:flutter/cupertino.dart';
import 'package:intl/intl.dart';
import 'package:auto_size_text/auto_size_text.dart';
import 'dart:io' show Platform;
class DateTimePicker extends StatefulWidget {
@override
_DateTimePickerState createState() => _DateTimePickerState();
}
class _DateTimePickerState extends State<DateTimePicker> {
DateTime _date = new DateTime.now();
TimeOfDay _time = new TimeOfDay.now();
Duration initialtimer = new Duration();
DateTime _datePicked;
TimeOfDay _timePicked;
@override
void initState() {
// timeController.addListener(_time);
}
@override
Widget build(BuildContext context) {
return Container(
child: Column(
mainAxisAlignment: MainAxisAlignment.spaceEvenly,
children: <Widget>[
Row(
mainAxisAlignment: MainAxisAlignment.start,
// mainAxisSize: MainAxisSize.min,
children: <Widget>[
dateContainer(),
timeContainer()
],
),
Row(
mainAxisAlignment: MainAxisAlignment.start,
children: <Widget>[
customDatePicker(context),
customTimePicker(context)
],
),
],
),
);
}
Widget customTimePicker(BuildContext context) {
return Padding(
padding: const EdgeInsets.only(left: 12.0),
child: FlatButton(
child: Text('Time', style: TextStyle(
color: Colors.white
),),
color: Colors.deepOrange,
onPressed: () => _selectedTime(context)
),
);
}
Future<Null> _selectedTime(BuildContext context) async {
_timePicked = await showTimePicker(
context: context,
initialTime: _time);
if (_timePicked != null) {
setState(() {
_time = _timePicked;
});
}
}
Widget timeContainer() {
return Container(
width: 100,
height: 100,
child: Padding(
padding: const EdgeInsets.only(left: 16.0, top: 16.0,bottom: 16.0),
child: Container(
decoration: BoxDecoration(
border: Border.all(
width: .5,
color: Colors.black
)
),
child: timeFormater(),
)
),
);
}
Widget timeFormater() {
return Column(
children: <Widget>[
SizedBox(
height: 20.0,
),
_timePicked != null
? TimeOfDay(hour: _timePicked.hour, minute: _timePicked.minute)
: SizedBox(
width: 0.0,
height: 0.0,
),
],
);
}
}

This will correctly format TimeOfDay for you:
final localizations = MaterialLocalizations.of(context);
final formattedTimeOfDay = localizations.formatTimeOfDay(timeOfDay);
