Issue calling isAvailable method @ionic-native/email-composer

Question

Current behavior: I have installed the email composer components as per the ionic documentation and the isAvailable function is not available. I have read various documents regarding this subject but cannot find any way to get the method to work.

The rest of the plugin works perfectly when sending emails on my Android device so the plugin is definitely installed and working.

Error: Uncaught (in promise): TypeError: EmailComposer.getPlugin(...).isAvailable is not a function

Expected behavior: I would expect the isAvailable method to return true or false.

Steps to reproduce:

$ ionic start myApp blank
$ ionic cordova plugin add cordova-plugin-email-composer
$ npm install @ionic-native/email-composer

Related code:

import { Component } from '@angular/core';
import { EmailComposer } from '@ionic-native/email-composer/ngx';

@Component({
    selector: 'app-home',
    templateUrl: 'home.page.html',
    styleUrls: ['home.page.scss']
})
export class HomePage {
    constructor(private emailComposer: EmailComposer) {}

    public canEmail: boolean = false;

    ionViewDidEnter() {
        this.emailComposer.isAvailable().then((available: boolean) => {
            if (available) {
                this.canEmail = true;
            }
        });
    }    
}

Seems, the plugin is not installed. Did you add the plugin like, cordova plugin add cordova-plugin-email-composer — Maheswaran Ravisankar
Yes I did, I followed the instructions on the Ionic website and the module has been installed into the node_modules folder and if I bypass this call to isAvailable then the send email GMail form is initiated as one would expect. — Andrew HB
Reading the plugin's repo, I see isAvailable is replaced with hasClient and hasAccount — Maheswaran Ravisankar
Unfortunately those functions are not supported via the @ionic-native/email-composer module :/ — Andrew HB

Just in case it helps anybody else out there.

After a few days of investigation I have come to the conclusion that the cordova-plugin-email-composer is out of line with the Ionic native library. I have attempted to resolve the issue myself and my @ionic-native fork is available here @ionic-native the specific file I have changed is located here src\@ionic-native\plugins\email-composer.index.ts.

I have created a pull request in the main ionic-native repository but its my first attempt of any kind contributing to a project like this so not sure on the outcome!
