extension_google_sign_in_as_googleapis_auth

extension_google_sign_in_as_googleapis_auth

A bridge package between Flutter's google_sign_in plugin and Dart's googleapis package, that is able to create googleapis_auth-like AuthClient instances directly from the GoogleSignIn plugin.

Usage

This package is implemented as an extension method on top of the GoogleSignIn plugin.

In order to use it, you need to add a dependency to your pubspec.yaml. Then, wherever you're importing package:google_sign_in/google_sign_in.dart, add the following:

import 'package:extension_google_sign_in_as_googleapis_auth/extension_google_sign_in_as_googleapis_auth.dart';

From that moment on, your GoogleSignIn instance will have an additional Future<AuthClient?> authenticatedClient() method that you can call once your sign in is successful to retrieve an AuthClient.

That object can then be used to create instances of googleapis API clients:

// Retrieve an [auth.AuthClient] from the current [GoogleSignIn] instance.
final auth.AuthClient? client = await _googleSignIn.authenticatedClient();

assert(client != null, 'Authenticated client missing!');

// Prepare a People Service authenticated client.
final PeopleServiceApi peopleApi = PeopleServiceApi(client!);
// Retrieve a list of the `names` of my `connections`
final ListConnectionsResponse response =
    await peopleApi.people.connections.list(
  'people/me',
  personFields: 'names',
);

Example

This package contains a modified version of Flutter's Google Sign In example app that uses package:googleapis' API clients, instead of raw http requests.
