DatePicker - if only year picked reset to initial date

Steps to Reproduce

Open DatePicker in application for example like this:

    var now = DateTime.now();
    var selectedDate = DateTime(now.year - 3);
    if (_birthDateController.text.isNotEmpty)
      selectedDate = dateFormat.parse(_birthDateController.text);
    final DateTime picked = await showDatePicker(
        context: context,
        initialDatePickerMode: DatePickerMode.year,
        initialDate: selectedDate,
        firstDate: DateTime(now.year - 100),
        locale: Localizations.localeOf(context),
        lastDate: now);

And select 2009 year. Do not pick day. Click ok button in picker dialog.

Expected results:
Picker date result == 01.01.2009

Actual results:
Picker date result == initialDate

Hi @marinat
Can you please provide your flutter doctor -v and a minimal complete reproducible code sample?
Thank you

I need a minimal code sample that reproduces the issue as well.

code sample

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

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

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      home: MyHomePage(),
    );
  }
}

class MyHomePage extends StatefulWidget {
  @override
  _MyHomePageState createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  DateTime currentDate;

  Future<void> _selectDate(BuildContext context) async {
    final DateTime pickedDate = await showDatePicker(
        context: context,
        initialDate: DateTime.now(),
        initialDatePickerMode: DatePickerMode.year,
        firstDate: DateTime(2015),
        lastDate: DateTime(2050));
    if (pickedDate != null && pickedDate != currentDate)
      setState(() {
        currentDate = pickedDate;
      });
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text("DatePicker"),
      ),
      body: Center(
        child: Column(
          mainAxisSize: MainAxisSize.min,
          children: <Widget>[
            Text(currentDate != null ? currentDate.toString() : 'No date'),
            RaisedButton(
              onPressed: () => _selectDate(context),
              child: Text('Select date'),
            ),
          ],
        ),
      ),
    );
  }
}

I think that's not a really bug, but it's confusing users who has for example birthday at first day of month.

@marinat

Hi @marinat
I think this is not a bug as well. This dialog is expected to be used to select both, the year and day. If you only select the year the selected date is not complete.

but it's confusing users who has for example birthday at first day of month

I'm not sure what is confusing here, if birthday is at first day of month user just need to select the month and then the first day of that month.
