Unable to use TranslateLoader in Angular 7

[ramoncarreras]

My fault,
changing my app.module.ts to this makes translation work:

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { RouteReuseStrategy } from '@angular/router';
import { HttpClient, HttpClientModule } from '@angular/common/http';
import { TranslateLoader, TranslateModule } from '@ngx-translate/core';
import { NgxWebstorageModule } from 'ngx-webstorage';

import { IonicModule, IonicRouteStrategy } from '@ionic/angular';
import { SplashScreen } from '@ionic-native/splash-screen/ngx';
import { Insomnia } from '@ionic-native/insomnia/ngx';
import { Device } from '@ionic-native/device/ngx';

import { AppComponent } from './app.component';
import { AppRoutingModule } from './app-routing.module';
import { ComponentsModule } from './components/components.module';
import { TranslateLoaderService } from './services/translate-loader/translate-loader.service';

@NgModule({
    declarations: [
        AppComponent,
    ],
    entryComponents: [],
    imports: [
        BrowserModule,
        IonicModule.forRoot({
            backButtonText: '',
            backButtonIcon: 'ios-arrow-back',
            spinner: 'dots',
            refreshingSpinner: 'dots',
            loadingSpinner: 'dots',
            infiniteLoadingSpinner: 'dots',
        }),
        NgxWebstorageModule.forRoot({prefix: 'tax-rd', separator: '.'}),
        AppRoutingModule,
        ComponentsModule,
        HttpClientModule,
        TranslateModule.forRoot({
            loader: {
                provide: TranslateLoader,
                useClass: TranslateLoaderService,
            },
        }),
    ],
    providers: [
        SplashScreen,
        Insomnia,
        Device,
        {provide: RouteReuseStrategy, useClass: IonicRouteStrategy},
    ],
    bootstrap: [AppComponent],
})
export class AppModule {
}
