im trying to use ionic 4 google-maps@5.0.0-beta.20
i am following these slides: https://docs.google.com/presentation/d/1zlkmoSY4AzDJc_P4IqWLnzct41IqHyzGkLeyhlAxMDE/edit#slide=id.g282d0a7bfd_0_140
I get this error: "TypeError: Cannot read property 'BaseClass' of null"
newlocation.page.html:
<ion-content>
<h3>Ionic GoogleMaps Starter</h3>
<div id="map_canvas">
</div>
</ion-content>
newlocation.page.scss:
map_canvas {
height: 90%;
}
newlocation.page.ts:
import { Component, OnInit } from '@angular/core';
import { Platform } from '@ionic/angular';
import { GoogleMaps, GoogleMap } from '@ionic-native/google-maps';
@Component({
selector: 'app-newlocation',
templateUrl: './newlocation.page.html',
styleUrls: ['./newlocation.page.scss'],
})
export class NewlocationPage implements OnInit {
map: GoogleMap;
constructor(private platform: Platform) { }
async ngOnInit() {
await this.platform.ready();
await this.loadMap();
}
loadMap() {
this.map = GoogleMaps.create('map_canvas');
}
}
package.json:
....
"@ionic-native/core": "5.0.0-beta.14",
"@ionic-native/google-maps": "^5.0.0-beta.20"
....
"cordova-plugin-googlemaps": {
"API_KEY_FOR_ANDROID": (API-KEY),
"PLAY_SERVICES_VERSION": "15.0.1",
"ANDROID_SUPPORT_V4_VERSION": "27.+"
}
In Ionic V4, we need to define loadMap() method async call which will return promise.
I got it working,
I only deleted 'ion-content' and let 'div id="map_canvas"' alone
my info:
package.json:
newlocation.page.html:
newlocation.page.scss:
newlocation.page.ts:
newlocation.module.ts
Note: for web you have to use 'ionic cordova run browser' not 'ionic serve'
