Problem with Google Maps and Ionic 2. Missing plugin

Good morning,

I'm trying to show Google Maps in my app on Ionic2.

The following warnings are being given to me by console:

  

Native: tried accessing the GoogleMap plugin but it's not installed.

     

Install the GoogleMap plugin: 'ionic plugin add plugin.google.maps.Map'

I have already added the plugin theoretically with this instruction.

  

cordova plugin add cordova-plugin-googlemaps --variable API_KEY_FOR_ANDROID="YOUR_API_KEY_IS_HERE"

In fact, if I execute it again, it gives me the message:

Plugin "cordova-plugin-googlemaps" already installed on android.

I do not know what else to do. I have followed step by step tutorials of all kinds and color. And there is no way to show the map.

The code:

Component.ts

    import { Component } from '@angular/core';

import {NavController, Platform} from 'ionic-angular';
import {GoogleMap, GoogleMapsEvent, GoogleMapsLatLng} from 'ionic-native';

@Component({
    templateUrl: 'location-page.html'
})
export class LocationPage {

    private map: GoogleMap;
    constructor(private navCtrl: NavController,private platform:Platform) {
    this.platform.ready().then(() => {
        this.setupGoogleMap()
       });
    }

    setupGoogleMap(){
    // somewhere in your component
    try{
        let location = new GoogleMapsLatLng(40.409202,-3.732649);
        this.map = new GoogleMap('map', {
            'backgroundColor': 'white',
            'controls': {
                'compass': true,
                'myLocarionButton': true,
                'indoorPicker': true,
                'zoom': true
            },
            'gestures': {
                'scroll': true,
                'tilt': true,
                'rotate': true,
                'zoom': true
            },
            'camera': {
                'latLng': location,
                'tilt': 30,
                'zoom': 15,
                'bearing': 50
            }
        });
       this.map.on(GoogleMapsEvent.MAP_READY).subscribe(() => {
           console.log('Map is ready!');
       })
    } catch(e){
        e => console.log(e);
    }

  }
    latitud: number = 40.409202;
    longitud: number = -3.732649;

}

component.html

<ion-content>
  <div id="map"></div>
  </ion-content>

Code after trying the link: link

export class LocationPage {

    private map: GoogleMap;
    constructor(private navCtrl: NavController) {}

        lat: number = 51.678418;
        lng: number = 7.809007;

HTML:

<ion-col>
      <sebm-google-map [latitude]="lat" [longitude]="lng">
        <sebm-google-map-marker [latitude]="lat" [longitude]="lng"></sebm-google-map-marker>
      </sebm-google-map>
      </ion-col>

It still does not work even though it no longer fails.
