AngularFireAuth injection

[jadosfer]

Hi everybody, how are you? I write for a query. I want to authenticate user using AngularFireAuth with google and there seems to be an error in the dependency injection. I looked for various alternatives, even adding AngularFireAuthModule to AppModule.ts, but couldn't get it to work. The component is not displayed (it is simply a button) and I get this error in the console:
ERROR Error: Uncaught (in promise): NullInjectorError: R3InjectorError(AppModule)[AngularFireAuth -> AngularFireAuth -> AngularFireAuth]:
NullInjectorError: No provider for AngularFireAuth!
NullInjectorError: R3InjectorError(AppModule)[AngularFireAuth -> AngularFireAuth -> AngularFireAuth]:

my component ts file is:
import { Component, OnInit } from '@angular/core';
import * as firebase from 'firebase/app';
import {AngularFireAuth} from 'angularfire2/auth'
@component({
selector: 'app-login',
templateUrl: './login.component.html',
styleUrls: ['./login.component.scss']
})
export class LoginComponent implements OnInit {
constructor(private afAuth: AngularFireAuth) {}
login() {
this.afAuth.auth.signInWithRedirect(new firebase.auth.GoogleAuthProvider());
}
}
and my component html file is:
<button (click)="login()" mat-raised-button color="accent">Login with google
