Flutter Format Time of Day from time picker

Question

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);
