@marcusaaronb
I was also facing the same issue

later, I realized that I missed 'SocialLoginModule' to include in my main module. This might be the case for you as well.

@praveen-vasudhaika I am also facing the same issue. How did you get to resolve? Could you please brief?
Thanks!

@as88425
I had missed to include > SocialLoginModule in imports under NgModule decorator on my main module:

@NgModule({
  imports: [
    ...
    SocialLoginModule
  ],
  declarations: [...],
  providers : [
    {
      provide: AuthServiceConfig,
      useFactory: getAuthServiceConfigs
    }
  ]
})

hope this helps!!

@praveen-vasudhaika as per your steps I also did in my signin.component.ts

@Component({
  selector: 'app-signin',
  templateUrl: './signin.component.html',
  styleUrls: ['./signin.component.css'],
  providers: [SocialLoginModule, AuthService]
})

it's workin for me now

Through normal angular build its working fine but when i used Webpack build , its throwing exception "Can't resolve all parameters in AppComponent (?) e.g AuthService"

Do you have any solution for this :)

import { Component, OnInit } from '@angular/core'
import { SocialLoginModule } from 'angularx-social-login'
import { AuthService } from "angularx-social-login";
import { GoogleLoginProvider } from "angularx-social-login";
import { SocialUser } from "angularx-social-login";

@component({
selector: 'app-easy',
templateUrl: '../../Scripts/Home/Components/appComponent.html',
providers: [SocialLoginModule,AuthService]
})
export class AppComponent implements OnInit
{
myName: string
user: SocialUser
loggedIn:boolean

constructor(private authService: AuthService) {
    this.myName = "sujit"
}

getName = ()=> {
    return this.myName
}
signInWithGoogle(): void {
    this.authService.signIn(GoogleLoginProvider.PROVIDER_ID);
}
signOut(): void {
    this.authService.signOut();
}
ngOnInit() {
    this.authService.authState.subscribe((user) => {
        this.user = user;
        this.loggedIn = (user != null);
    });
}
