Help App Version

Ionic Framework ionic-v3
1

I’m no expert.
Sorry if the question is insignificant, but as I’m learning to ask.

How to use native ionic 2, in the following situation:
How to print in html(AppVersion.getVersionCode();)?
What is the process to get the result? Will the constructor? Could you give me a simple example of use? The way that the documentation I could not understand.

in .js
import {AppVersion} from ‘ionic-native’;

AppVersion.getAppName();
AppVersion.getPackageName();
AppVersion.getVersionCode();
AppVersion.getVersionNumber();

in .html
<ion-card-content> {{VERSAO}} </ion-card-content>

I have already installed the plugin in my project.
$ ionic plugin add cordova-plugin-app-version

I think all those functions return a promise rather than a value. Try something like this in your constructor:

this.versionNumber = 'unknown';

if(this.platform.is('cordova')) {
    AppVersion.getVersionNumber().then((s) => {
    this.versionNumber = s;
  })
}

and then use

{{versionNumber}}

in your html template.

The “platform.is” wrapper is to avoid errors if you’re testing in a browser.

Might be a scope problem, are you sure “this” is referring to the correct namespace?
