easy_google_sign_in #

One-liner Google Sign-In for Firebase Auth — just call a function in your button’s onPressed, or use the included EasyGoogleSignInButton.

Why? #

You shouldn’t write boilerplate every time. This package wraps:

• firebase_auth for Firebase login
• google_sign_in for mobile tokens
• Web popup flow for Flutter web

Quick Start #

1. Add dependencies to your app (the consumer of this package):

dependencies:
  firebase_core: ^3.0.0
  firebase_auth: ^5.0.0
  easy_google_sign_in: ^0.1.0

2. Do the usual Firebase setup (manual, once per app):

• Add google-services.json (Android) / GoogleService-Info.plist (iOS)
• Add SHA-1/SHA-256 for Android in Firebase console (keytool)
• For Web, add Firebase config (or use FlutterFire CLI)
• Call Firebase.initializeApp() in main()

3. Use it:

ElevatedButton(
  onPressed: easyGoogleSignInOnPressed(
    onSuccess: (cred) => print('Welcome ${cred.user?.displayName}!'),
  ),
  child: const Text('Sign in with Google'),
);

or

EasyGoogleSignInButton(
  onSuccess: (cred) => print('Welcome ${cred.user?.email}!'),
)

Sign out #

await signOutFromGoogle();

Options #

EasyGoogleSignInOptions(
  scopes: ['email', 'profile'],
  iosClientId: null,
  hostedDomain: null,
  requestServerAuthCode: false,
  showDefaultLoadingOverlay: true,
)

Notes #

• This package does not auto-initialize Firebase for you; apps differ.
• On iOS/macOS, if you use a custom client ID, pass it via iosClientId.
• On Web we use signInWithPopup.

Notes for google_sign_in v7.x #

This package uses the new v7 API (singleton + initialize() + authenticate()). Only an ID token is provided by the plugin; accessToken is no longer exposed. For Firebase Auth this is sufficient.
