title: How to set the default date for the Date picker in flutter?
body: <p>Below code is working properl. But I don't know how to set the default date value!</p>
  
  <pre><code>final dateFormat = DateFormat("dd-M-yyyy");
  
  DateTimePickerFormField(
      dateOnly: true,
      format: dateFormat,
      decoration: InputDecoration(labelText: 'Select Date'),
      initialDate: DateTime.now(),
      onSaved: (value){
          _date = value;
      },
  ),
  </code></pre>
  
  <p>I'm using <code>datetime_picker_formfield:</code> flutter library.</p>
  
  <p>I'm trying to do that with <code>initialDate: DateTime.now()</code> initial date property but it was not displaying anything as an initial value.</p>
  
  <p>Thanks in advance!</p>
