CallNumber's .isCallSupported() throws "plugin_not_installed" error, but the functionality still works

I'm submitting a ...
[x] bug report
[ ] feature request
[ ] support request

Current behavior:

Call Number plugin's .isCallSupported() method throws "plugin_not_installed" error. Even though the plugin is installed AND work as expected.

Expected behavior:

The promise returned by the method should resolve to true on devises that support the functionality.

Steps to reproduce:

Install the plugin as usual:

$ ionic cordova plugin add call-number
$ npm install --save @ionic-native/call-number

Add the module to providers list:

import { CallNumber } from '@ionic-native/call-number';

...

@NgModule({
  ...

  providers: [
    ...
    CallNumber
    ...
  ]
  ...
})
export class AppModule { }

Related code:

import { Component } from '@angular/core';
import { CallNumber } from "@ionic-native/call-number";

@Component({
  selector: 'page-home',
  template: `
    {{isSupported | json}}
    <button ion-button (click)="callNumber()">CallNumber</button>
  `
})
export class HomePage {
  isSupported = false;

  constructor(public phone: CallNumber) {
    this.phone.isCallSupported()
      .then(support => this.isSupported = support)
      .catch(err => this.isSupported = err);
  }

  callNumber(){
    this.phone.callNumber("123456789", true)
      .then(res => this.result = res)
      .catch(err => this.result = err);
  }
}

The plugin does not even have the function isCallSupported() and @ionic-native plugin code doesn't seem to be doing anything by itself. I wonder why the function is even there.

[uzbekjon]

The plugin has it here and iOS as well as Android native codes in the plugin also have it.

I would like to reopen this issue as the exact behaviour is still occurring.

Im having 2 ionic project, It works fine on one. Another it's not working at all. No respond at all when executing the function

@ng22792 my solution for your problem is that try remove your ionic platform based on ( https://ionicframework.com/docs/cli/cordova/platform/ ) and then add the platform back. This will download all the missed out plugin in platform.
