google_sign_in_android

The Android implementation of google_sign_in.

Usage

This package is endorsed, which means you can simply use google_sign_in normally. This package will be automatically included in your app when you do, so you do not need to add it to your pubspec.yaml.

However, if you import this package to use any of its APIs directly, you should add it to your pubspec.yaml as usual.

Integration

To use Google Sign-In, you'll need to register your application, either using Firebase, or directly with Google Cloud Platform.

• If you are use the google-services.json file and Gradle-based registration system, no identifiers need to be provided in Dart when initializing the GoogleSignIn instance when running on Android.
• If you are not using google-services.json, you need to pass the client ID of the web application you registered as the serverClientId when initializing the GoogleSignIn instance.

If you encounter APIException errors, double-check that you have followed all of the registration steps in the instructions above.

You will also need to enable any OAuth APIs that you want, using the Google Cloud Platform API manager. For example, if you want to mimic the behavior of the Google Sign-In example app, you'll need to enable the Google People API.
