Flash messages in ember js not working. Object undefined when creating a flash object

Component.


  

<button > Click for Flash </button>

component js

import Ember from 'ember';

export default Ember.Component.extend({
    flashMessages: Ember.inject.service(),
    actions:{
        getFlash(){
            alert(this.get('flashMessages'))
            const flashMessages = Ember.get(this, 'flashMessages');
            flashMessages.success('Success!');
        }
    }
});

Error Message: Uncaught TypeError:

Alert message: Undefined

So the service injection is not working for some reason. What am I missing. Guide I referred to: http://ift.tt/2iqFJnM

ember install ember-bootstrap ember install ember-cli-flash

These two were installed.
