如何在ionic项目中添加原生datepicker？

npm install -g cordova
npm install -g ionic

ionic start myApp blank
cd myApp

ionic cordova plugin add cordova-plugin-datepicker

import { Component } from '@angular/core';
import { Platform } from 'ionic-angular';
declare var cordova: any;

@Component({
  selector: 'page-home',
  templateUrl: 'home.html'
})
export class HomePage {
  constructor(public platform: Platform) {
    platform.ready().then(() => {
      this.openDatePicker();
    });
  }

  openDatePicker() {
    if (this.platform.is('cordova')) {
      cordova.plugins.datePicker.show({
        date: new Date(),
        mode: 'date',
        androidTheme: 5
      }, (date) => {
        console.log('Selected date: ' + date);
      });
    }
  }
}

ionic cordova run android
