Meta tags not display on page view source using angular 6.1

I'm using Angular, I want to add meta tags dynamically.

I am using form : https://www.npmjs.com/package/@ngx-meta/core

npm install @ngx-meta/core --save


I Tried the code below, it is showing in inspect element (console), but it is not showing on source code:

import { NgModule } from '@angular/core';
import { MetaGuard } from '@ngx-meta/core';

import { MetaModule, MetaLoader, MetaStaticLoader, PageTitlePositioning } from '@ngx-meta/core';

import { Routes, RouterModule } from '@angular/router';
import { HomeComponent } from './home/home.component';
import { AboutComponent } from './about/about.component';
import { DashboardComponent } from './dashboard/dashboard.component';
import { ChildrouterComponent } from './about/childrouter/childrouter.component';

const routes: Routes = [
{
path: '',
canActivateChild: [MetaGuard],
children: [
{
path: 'home',
component: HomeComponent,
data: {
meta: {
title: 'home home',
keywords: 'home,home,home,home,home',
description: 'Home, home sweet home... and what?',
'og:image': 'https://upload.wikimedia.org/wikipedia/commons/f/f8/superraton.jpg',
'og:type': 'website',
'og:locale': 'en_US',
'og:locale:alternate': 'en_US,nl_NL,tr_TR'
}
}
},
{
path: 'about',
component: AboutComponent,
data: {
meta: {
title: 'about hello',
keywords: 'about,about,about,about,about,about,about',
description: 'Have you seen my rubber hello?',
'og:image': 'https://upload.wikimedia.org/wikipedia/commons/f/f8/superraton.jpg',
'og:type': 'website',
'og:locale': 'en_US',
'og:locale:alternate': 'en_US,nl_NL,tr_TR'
}
}
},
{
path: 'dashboard',
component: DashboardComponent,
data: {
meta: {
title: 'dashboard hello',
keywords: 'dashboard,dashboard,dashboard,dashboard,dashboard,dashboard,dashboard',
description: 'Have you seen my dashboard hello?',
'og:image': 'https://upload.wikimedia.org/wikipedia/commons/f/f8/superraton.jpg',
'og:type': 'website',
'og:locale': 'en_US',
'og:locale:alternate': 'en_US,nl_NL,tr_TR'
}
}
}
]
}
]

@NgModule({
imports: [RouterModule.forRoot(routes),
MetaModule.forRoot()
],

exports: [RouterModule]
})
export class AppRoutingModule { }


It's working fine in inspect element but not showing any meta tags in page view source .
