1 - Google Login - Platform integration

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

This plugin requires iOS 9.0 or higher.

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: -->

<!-- End of the Google Sign-in Section -->

iOS additional requirement

Note that according to https://developer.apple.com/sign-in-with-apple/get-started, starting June 30, 2020, apps that use login services must also offer a "Sign in with Apple" option when submitting to the Apple App Store.

Consider also using an Apple sign in plugin from pub.dev.

The Flutter Favorite sign_in_with_apple plugin could be an option.
