google_sign_in #

pub package

A Flutter plugin for Google Sign In.

Note: This plugin is still under development, and some APIs might not be available yet. Feedback and Pull Requests are most welcome!

Android integration #

To access Google Sign-In, you'll need to make sure to register your application.

You don't need to include the google-services.json file in your app unless you are using Google services that require it. You do need to enable the 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 sample app, you'll need to enable the Google People API.

Make sure you've filled out all required fields in the console for OAuth consent screen. Otherwise, you may encounter APIException errors.

iOS integration #

  1. First register your application.
  2. Make sure the file you download in step 1 is named GoogleService-Info.plist.
  3. Move or copy GoogleService-Info.plist into the [my_project]/ios/Runner directory.
  4. Open Xcode, then right-click on Runner directory and select Add Files to "Runner".
  5. Select GoogleService-Info.plist from the file manager.
  6. A dialog will show up and ask you to select the targets, select the Runner target.
  7. Then add the CFBundleURLTypes attributes below into the [my_project]/ios/Runner/Info.plist file.
<!-- Put me in the [my_project]/ios/Runner/Info.plist file -->
<!-- Google Sign-in Section -->
<key>CFBundleURLTypes</key>
<array>
	<dict>
		<key>CFBundleTypeRole</key>
		<string>Editor</string>
		<key>CFBundleURLSchemes</key>
		<array>
			<!-- TODO Replace this value: -->
			<!-- Copied from GoogleService-Info.plist key REVERSED_CLIENT_ID -->
			<string>com.googleusercontent.apps.861823949799-vc35cprkp249096uujjn0vvnmcvjppkn</string>
		</array>
	</dict>
</array>
<!-- End of the Google Sign-in Section -->

Usage #

Import the package #

To use this plugin, follow the plugin installation instructions.

Use the plugin #

Add the following import to your Dart code:

import 'package:google_sign_in/google_sign_in.dart';

Initialize GoogleSignIn with the scopes you want:

GoogleSignIn _googleSignIn = GoogleSignIn(
  scopes: [
    'email',
    'https://www.googleapis.com/auth/contacts.readonly',
  ],
);

Full list of available scopes.

You can now use the GoogleSignIn class to authenticate in your Dart code, e.g.

Future<void> _handleSignIn() async {
  try {
    await _googleSignIn.signIn();
  } catch (error) {
    print(error);
  }
}

Issues and feedback #

4.0.7 #

  • Switch from using api to implementation for dependency on play-services-auth, preventing version mismatch build failures in some Android configurations.

4.0.6 #

  • Fixed the PlatformException leaking from catchError() in debug mode.

4.0.5 #

  • Update README with solution to APIException errors.

4.0.4 #

  • Revert changes in 4.0.3.

4.0.3 #

  • Update guava to 27.0.1-android.
  • Add correct @NonNull annotations to reduce compiler warnings.

4.0.2 #

  • Add missing template type parameter to invokeMethod calls.
  • Bump minimum Flutter version to 1.5.0.
  • Replace invokeMethod with invokeMapMethod wherever necessary.

4.0.1+3 #

  • Update example to gracefully handle null user information.

4.0.1+2 #

  • Fix README.md to correctly spell GoogleService-Info.plist.

4.0.1+1 #

  • Remove categories.

4.0.1 #

  • Log a more detailed warning at build time about the previous AndroidX migration.

4.0.0+1 #

  • Added a better error message for iOS when the app is missing necessary URL schemes.

4.0.0 #

  • Breaking change. Migrate from the deprecated original Android Support Library to AndroidX. This shouldn't result in any functional changes, but it requires any Android apps using this plugin to also migrate if they're using the original support library.

    This was originally incorrectly pushed in the 3.3.0 update.

3.3.0+1 #

  • Revert the breaking 3.3.0 update. 3.3.0 was known to be breaking and should have incremented the major version number instead of the minor. This revert is in and of itself breaking for anyone that has already migrated however. Anyone who has already migrated their app to AndroidX should immediately update to 4.0.0 instead. That's the correctly versioned new push of 3.3.0.

3.3.0 #

  • BAD. This was a breaking change that was incorrectly published on a minor version upgrade, should never have happened. Reverted by 3.3.0+1.

  • Breaking change. Migrate from the deprecated original Android Support Library to AndroidX. This shouldn't result in any functional changes, but it requires any Android apps using this plugin to also migrate if they're using the original support library.

3.2.4 #

  • Increase play-services-auth version to 16.0.1

3.2.3 #

  • Change google-services.json and GoogleService-Info.plist of example.

3.2.2 #

  • Don't use the result code when handling signin. This results in better error codes because result code always returns "cancelled".

3.2.1 #

  • Set http version to be compatible with flutter_test.

3.2.0 #

  • Add support for clearing authentication cache for Android.

3.1.0 #

  • Add support to recover authentication for Android.

3.0.6 #

  • Remove flaky displayName assertion

3.0.5 #

  • Added missing http package dependency.

3.0.4 #

  • Updated Gradle tooling to match Android Studio 3.1.2.

3.0.3+1 #

  • Added documentation on where to find the list of available scopes.

3.0.3 #

  • Added support for games sign in on Android.

3.0.2 #

  • Updated Google Play Services dependency to version 15.0.0.

3.0.1 #

  • Simplified podspec for Cocoapods 1.5.0, avoiding link issues in app archives.

3.0.0 #

  • Breaking change. Set SDK constraints to match the Flutter beta release.

2.1.2 #

  • Added a Delegate interface (IDelegate) that can be implemented by clients in order to override the functionality (for testing purposes for example).

2.1.1 #

  • Fixed Dart 2 type errors.

2.1.0 #

  • Enabled use in Swift projects.

2.0.1 #

  • Simplified and upgraded Android project template to Android SDK 27.
  • Updated package description.

2.0.0 #

  • Breaking change. Upgraded to Gradle 4.1 and Android Studio Gradle plugin 3.0.1. Older Flutter projects need to upgrade their Gradle setup as well in order to use this version of the plugin. Instructions can be found here.
  • Relaxed GMS dependency to [11.4.0,12.0[

1.0.3 #

  • Add FLT prefix to iOS types

1.0.2 #

  • Support setting foregroundColor in the avatar.

1.0.1 #

  • Change GMS dependency to 11.+

1.0.0 #

  • Make GoogleUserCircleAvatar fade profile image over the top of placeholder
  • Bump to released version

0.3.1 #

  • Updated GMS to always use latest patch version for 11.0.x builds

0.3.0 #

  • Add a new GoogleIdentity interface, implemented by GoogleSignInAccount.
  • Move GoogleUserCircleAvatar to "widgets" library (exported by base library for backwards compatibility) and make it take an instance of GoogleIdentity, thus allowing it to be used by other packages that provide implementations of GoogleIdentity.

0.2.1 #

  • Plugin can (once again) be used in apps that extend FlutterActivity
  • signInSilently is guaranteed to never throw
  • A failed sign-in (caused by a failing init step) will no longer block subsequent sign-in attempts

0.2.0 #

  • Updated dependencies
  • Breaking Change: You need to add a maven section with the "https://maven.google.com" endpoint to the repository section of your android/build.gradle. For example:
allprojects {
    repositories {
        jcenter()
        maven {                              // NEW
            url "https://maven.google.com"   // NEW
        }                                    // NEW
    }
}

0.1.0 #

  • Update to use GoogleSignIn CocoaPod

0.0.6 #

  • Fix crash on iOS when signing in caused by nil uiDelegate

0.0.5 #

  • Require the use of support-v4 library on Android. This is an API change in that plugin users will need their activity class to be an instance of android.support.v4.app.FragmentActivity. Flutter framework provides such an activity out of the box: io.flutter.app.FlutterFragmentActivity
  • Ignore "Broken pipe" errors affecting iOS simulator
  • Update to non-deprecated application:openURL:options: on iOS

0.0.4 #

  • Prevent race conditions when GoogleSignIn methods are called concurrently (#94)

0.0.3 #

  • Fix signOut and disconnect (they were silently ignored)
  • Fix test (#10050)

0.0.2 #

  • Don't try to sign in again if user is already signed in

0.0.1 #

  • Initial Release
