showing error in auth about flutterchatapptutorial HOT 30 CLOSED

please help me this!

from flutterchatapptutorial.

please help me this!
Please click on get dependencies on the above popup
Make sure to add the latest version of dependencies and multidex in the pubspec.yaml and gradlebuild file from pub.dev .
for any help just comment.
The first error about user. ===>
rename the class and constructor name in user.dart file to AppUser and use AppUser instead of User because User is a firebase method.
and then
return user != null ? AppUser(userId: user.uid) : null;

The second error ===>
In new version of firebase FirebaseUser is replaced only with User. So change the complete function to::::
AppUser _userFromFirebaseUser(User user){
return user != null ? AppUser(userId: user.uid) : null;
}

The third error will be resolved when you do up above.

Error no 4 ====>
In new firebase AuthResults is replaced with UserCredentials. Please do that too.

Change the getLoggedInState function as following. It may help

setState(() {

setState(() {

});
}
});
});
