Flutter Tutorial For Beginners #9 - Adding Google Authentication with Firebase

A quick note: I'm using the following dependencies in pubspec.yaml:
firebase_database: ^4.3.0
firebase_core: "^0.5.0+1"
firebase_auth: "^0.18.1+2"
google_sign_in: ^4.5.6
I think several names were changed when the dependencies updated. At 11:44, the name "AuthResult" was changed into "UserCredential".
Hope this would save you a bit of time :)

Hi Tim. Can you recreate this video? I think there's some changes in Dart, Flutter and other libraries

[PradHolla]

Hello Tim. Great vid.
Did you come across this error:
Exception has occurred.
PlatformException (PlatformException(sign_in_failed, 10:, null))
It occured when I tried to sign in. I've followed everything though.

Edit: Resolved it.
1: The package names in Firebase Console and all of the Manifest files have to be the same.
2: Added a couple keys in Project Settings by running the command './gradlew signingReport' in Terminal inside android.

every time a login is performed, the void click function throws an error saying "The getter 'displayName' was called on null". The code when hot reloded after some time moves to the home page as expected. If you are facing the same error, make the change the function click as follows:-
void click() async {
await => {this.user = user});

Navigator.push(context,
MaterialPageRoute(builder: (context) =>
}

Google updates with null safety have made this video useless. Trying to fix Tim's code is like trying to slay a hydra, solve one problem and two more pops up. Can someone please post a newer version that reflects the new dependency releases?

Hi, what book did you use in your first year of computer science for the “Introduction to computing 1“ course ?

[doctorbroker]

For the ones who couldn't find "shape " parameter in Outline Button it's deprecated and it became OutlinedButton.

[miguelnuno]

I really enjoy this serie of videos, thanks for adding Firebase ASAP.

This code doesn't work with the new null safe dependencies.

[tadaspetra]

Try using didDependenciesChange instead of initState. And if you need any other help you can reach out 😊

[jameshowlett]

are firebase_auth and agoogle_sign_in the same for everyone or what? You just spawned them there first minute. You didn.t show where you copied them from

[aravindma]

"OutlineButton" has been deprecated.
