material-input date format

[EugenNekrasov]

Problem

material-input with dateParsing directive doesn't respect specified date format.

Example

import 'package:angular/angular.dart';
import 'package:angular_components/angular_components.dart';

@Component(
  selector: 'datepicker',
  template: '''
    <material-input
      dateParsing
      [dateFormat]="dateFormat"
      [date]="today"
    ></material-input>
  ''',
  directives: [
    materialInputDirectives,
    DateInputDirective,
  ],
)
class TestDatepickerComponent {
  Date today = Date.today();
  final DateFormat dateFormat = DateFormat('dd.MM.yyyy');
}

Result

There is inner exception during initialization:

Suggestion

In the component's code add parsing with _dateFormat field besides hard-coded formats.
