Ionic native datePicker not working

Ionic Native
1

Hi,
I’m trying to use datePicker native component, I followed the exact instructions and yet it doesn’t work.
When I press the button that calls the code to show the datePicker nothing happens!
I tried it on emulator and on real phone as well.

app.module.ts
import { DatePicker } from '@ionic-native/date-picker';

providers: [
   ...
    DatePicker
  ]

my-class.ts
import { DatePicker } from '@ionic-native/date-picker';

  constructor(private datePicker: DatePicker) { }

  onDate() {
    this.datePicker.show({
      date: new Date(),
      mode: 'date',
      androidTheme: this.datePicker.ANDROID_THEMES.THEME_HOLO_DARK
    }).then(
      date => console.log('Got date: ', date),
      err => console.log('Error occurred while getting date: ', err)
      );
  }

Please help!
