Add this script tag below in the head tag of web/index.html

<script src="https://apis.google.com/js/platform.js" async defer></script>

Import this in a ng2 component.

import 'package:angular2_google_signin/angular2_google_signin.dart';

// Add `GoogleSignin` on directives.
@Component(
    selector: 'app-component',
    templateUrl: 'template/app_component.html',
    directives: const [GoogleSignin]
)
class AppComponent {

  onGoogleSigninSuccess(GoogleSignInSuccess event) async {
    GoogleUser googleUser = event.googleUser;
    String id = googleUser.getId();
    assert(googleUser.isSignedIn());
    BasicProfile profile = googleUser.getBasicProfile();
    print('ID: ' + profile.getId()); // Do not send to your backend! Use an ID token instead.
    assert(profile.getId() == id);
    print('Name: ' + profile.getName());
    print('Image URL: ' + profile.getImageUrl());
    print('Email: ' + profile.getEmail());
    AuthResponse response = googleUser.getAuthResponse();
    print('id_token: ' + response.id_token);
    print('access_token: ' + response.access_token.toString());
    print('login_hint: ' + response.login_hint);
    print('scope: ' + response.scope.toString());
    print('expires_in: ' + response.expires_in.toString());
    print('first_issued_at: ' + response.first_issued_at.toString());
    print('expires_at: ' + response.expires_at.toString());
    GoogleAuth auth =  getAuthInstance();
    GoogleUser user = auth.currentUser.get();
    assert(user.hashCode == googleUser.hashCode);
    await auth.signOut();
    print('User signed out.');
  }
}

In a ng2 component template, put <google-signin> with attributes of render options and init params. clientId attribute is required. You don't need to write google-signin-client_id meta tag.

<google-signin clientId="..." width="240" theme="dark" scope="email profile" longTitle="true"
                 (googleSigninSuccess)="onGgoogleSigninSuccess($event)"></google-signin>
