I want to get the access token from google sign and save it as a variable so I'll be able to push it to my own API , this question has been asked before but the answers are outdated . I'm using this package :Google sign in
her,s my log in code that i access through a button :
GestureDetector(
onTap: () {
_googleSignIn.signIn().catchError((e) {
print('Erorr');
});
;
},
To get access token when logged in with google use
final credential = GoogleAuthProvider.credential(
accessToken: googleAuth?.accessToken,
idToken: googleAuth?.idToken,
);
Full method:
import 'package:google_sign_in/google_sign_in.dart';
Future<UserCredential> signInWithGoogle() async {
// Trigger the authentication flow
final GoogleSignInAccount? googleUser = await GoogleSignIn().signIn();
// Obtain the auth details from the request
final GoogleSignInAuthentication? googleAuth = await googleUser?.authentication;
// Create a new credential
final credential = GoogleAuthProvider.credential(
accessToken: googleAuth?.accessToken,
idToken: googleAuth?.idToken,
);
// Once signed in, return the UserCredential
return await FirebaseAuth.instance.signInWithCredential(credential);
}
for document https://firebase.flutter.dev/docs/auth/social/
Future<bool> google() async {
try {
final googleUser = await googleSignIn.signIn();
final googleAuth = await googleUser.authentication;
final AuthCredential credential = GoogleAuthProvider.credential(
accessToken: googleAuth?.accessToken,// accessToken
idToken: googleAuth?.idToken,
);
users = (await auth.signInWithCredential(credential)).user;
if (users == null) {
return false;
}
return true;
} catch (e) {
print('this is error .......$e');
return null;
}
you can get the access token
googleAuth.accessToken //fellowing my code
Future<FirebaseUser> signInWithGoogle(SignInViewModel model) async {
model.state =ViewState.Busy;
GoogleSignInAccount googleSignInAccount = await _googleSignIn.signIn();
GoogleSignInAuthentication googleSignInAuthentication =
await googleSignInAccount.authentication;
AuthCredential credential = GoogleAuthProvider.getCredential(
accessToken: googleSignInAuthentication.accessToken,
idToken: googleSignInAuthentication.idToken,
);
AuthResult authResult = await _auth.signInWithCredential(credential);
_user = authResult.user;
assert(!_user.isAnonymous);
assert(await _user.getIdToken() != null);
FirebaseUser currentUser = await _auth.currentUser();
assert(_user.uid == currentUser.uid);
model.state =ViewState.Idle;
print("User Name: ${_user.displayName}");
print("User Email ${_user.email}");
}

After clicking sign in, choose an account pop comes up but if the user pressed back or outside of the pop-up it throws an error.
Error -
Sign in class -
class GoogleSignInProvider extends ChangeNotifier {
final googleSignIn = GoogleSignIn();
GoogleSignInAccount? _user;
GoogleSignInAccount get user => _user!;
Future googleLogin() async {
await googleSignIn.signOut();
final googleUser = await googleSignIn.signIn();
if (googleUser == null) return;
_user = googleUser;
final googleAuth = await googleUser.authentication;
final credential = GoogleAuthProvider.credential(

Sign out button -
TextButton(
onPressed: () async {
final googleCurrentUser = GoogleSignIn().currentUser;
if (googleCurrentUser != null) {
await GoogleSignIn().disconnect();
}
FirebaseAuth.instance.signOut();
Navigator.pop(context);
},
child: const Text(
'Yes',
style: TextStyle(color: primaryColor),
))
Instead of if (googleUser == null) return; try using if (googleUser == null) return null;.
Here is my sign in method;
Future<UserCredential?> signInWithGoogle() async {
final _googleSignIn = GoogleSignIn();
await _googleSignIn.disconnect().catchError((e, stack) {
print(e);
});
final GoogleSignInAccount? googleUser = await _googleSignIn.signIn();
// handling the exception when cancel sign in
if (googleUser == null) return null;
// Obtain the auth details from the request
final GoogleSignInAuthentication? googleAuth =
await googleUser.authentication;
// Create a new credential
final credential = GoogleAuthProvider.credential(
accessToken: googleAuth?.accessToken,
idToken: googleAuth?.idToken,
);
return await FirebaseAuth.instance.signInWithCredential(credential);
}
The sign out method;
Future signOut() async {
var result = await FirebaseAuth.instance.signOut();
return result;
}
This only happens in debugging, in release this won't be an issue.
Future googleSignIn() async {
final GoogleSignInAccount googleUser = await GoogleSignIn(
scopes: ['https://www.googleapis.com/auth/contacts.readonly']).signIn();
final GoogleSignInAuthentication googleAuth =
await googleUser.authentication;
final credential = GoogleAuthProvider.credential(
accessToken: googleAuth.accessToken,
idToken: googleAuth.idToken,

await FirebaseAuth.instance.signInWithCredential(credential);
}

If you make the return type of <UserCredential?> nullable, you'd be able to work with it.
//this UserCredential?
Future<UserCredential?> signInWithGoogle() async {
// Trigger the authentication flow
try {
final GoogleSignInAccount? googleUser = await (GoogleSignIn().signIn());
// Obtain the auth details from the request
final GoogleSignInAuthentication googleAuth = await googleUser!.authentication;
// Create a new credential
final GoogleAuthCredential credential = GoogleAuthProvider.credential(
accessToken: googleAuth.accessToken,
idToken: googleAuth.idToken,
) as GoogleAuthCredential;
// Once signed in, return the UserCredential
return await FirebaseAuth.instance.signInWithCredential(credential);
} catch (e) {
print(e);
return null ;
}
}
Right now I'm also facing this issue. Your code is fine. Run your app in Release mode and everything will work fine as expected. It's very strange behavior.
this only occurs in Emulators, not in the real devices.
I've been trying for a bit to implement login of youtube channels on my app. but all I could do was google accounts with google_sign_in 4.5.1
has any of you implemented this feature and can give me an hint? youtube docs are terrible
edit:
here's the code
class AuthService {
String oAuthClientId = '**hidden**'; // not used?
static List<String> scopes = [
'email',
'https://www.googleapis.com/auth/youtube', // Youtube scope
];
final FirebaseAuth auth = FirebaseAuth.instance;
GoogleSignIn googleSignIn = GoogleSignIn(
scopes: scopes,
);
Future<FirebaseUser> login() async {
final GoogleSignInAccount googleSignInAccount = await googleSignIn.signIn();
final GoogleSignInAuthentication googleSignInAuthentication = await googleSignInAccount.authentication;
final AuthCredential credential = GoogleAuthProvider.getCredential(
accessToken: googleSignInAuthentication.accessToken,
idToken: googleSignInAuthentication.idToken,
);
final token = googleSignInAuthentication.accessToken;
final AuthResult authResult = await auth.signInWithCredential(credential);
final FirebaseUser user = authResult.user;
assert(!user.isAnonymous);
assert(await user.getIdToken() != null);
final FirebaseUser currentUser = await auth.currentUser();
assert(user.uid == currentUser.uid);
var client = new http.Client();
return currentUser;
}
void signOut() {
auth.signOut();
googleSignIn.disconnect();
}
Future<FirebaseUser> getUser() async{
final FirebaseUser user = await auth.currentUser();
return user;
}
}
To display your youtube channels, you'll need to add the youtube scope https://www.googleapis.com/auth/youtube to your google login.
Prior to this, you must've setup enabled the Youtube api from your developer console. Read the Youtube API documentation for more information
Example login code:
login() async {
GoogleSignIn googleSignIn = GoogleSignIn(
scopes: [
'email',
'https://www.googleapis.com/auth/youtube', // Youtube scope
],
);
final GoogleSignInAccount googleSignInAccount = await googleSignIn.signIn();
final GoogleSignInAuthentication googleSignInAuthentication =
await googleSignInAccount.authentication;
final AuthCredential credential = GoogleAuthProvider.getCredential(
accessToken: googleSignInAuthentication.accessToken,
idToken: googleSignInAuthentication.idToken,
);
// You'll need this token to call the Youtube API. It expires every 30 minutes.
final token = googleSignInAuthentication.accessToken;
final AuthResult authResult = await auth.signInWithCredential(credential);
final FirebaseUser user = authResult.user;
assert(!user.isAnonymous);
assert(await user.getIdToken() != null);
final FirebaseUser currentUser = await auth.currentUser();
assert(user.uid == currentUser.uid);
}
Hello I am using flutter and I implemented correctly the google signIn but even by changing the scope I only get:
"Display name"
"Email"
"Img url"
Here is the code to make the user log in:
GoogleSignInAccount googleUser = await _googleSignIn.signIn();
// Step 2
GoogleSignInAuthentication googleAuth = await googleUser.authentication;
final AuthCredential credential = GoogleAuthProvider.getCredential(
accessToken: googleAuth.accessToken,
idToken: googleAuth.idToken,
);
print(googleAuth.toString());
final FirebaseUser user =
(await _auth.signInWithCredential(credential)).user;
// Step 3
updateUserData(user);
// Done
print("signed in " + user.displayName);
return user;
}
void updateUserData(FirebaseUser user) async {
DocumentReference ref = _db.collection('users').document(user.uid);
return ref.setData({
'uid': user.uid,
'email': user.email,
'photoURL': user.photoUrl,
'displayName': user.displayName,
'lastSeen': DateTime.now()
}, merge: true);
}
