我正在使用Firebase Google登录选项在我的项目中实现google登录方法,当在我的代码中添加以下行时,它会向我抛出如下错误:
A value of type 'AuthResult' can't be assigned to a variable of type 'FirebaseUser'
这是我的代码:
final FirebaseAuth _firebaseAuth = FirebaseAuth.instance;
final GoogleSignIn _googlSignIn = new GoogleSignIn();
Future<FirebaseUser> _signIn(BuildContext context) async {
Scaffold.of(context).showSnackBar(new SnackBar(
content: new Text('Sign in'),
));
final GoogleSignInAccount googleUser = await _googlSignIn.signIn();
final GoogleSignInAuthentication googleAuth =await googleUser.authentication;
final AuthCredential credential = GoogleAuthProvider.getCredential(
accessToken: googleAuth.accessToken,
idToken: googleAuth.idToken,
);
FirebaseUser userDetails = await _firebaseAuth.signInWithCredential(credential).user;
ProviderDetails providerInfo = new ProviderDetails(userDetails.providerId);
List<ProviderDetails> providerData = new List<ProviderDetails>();
providerData.add(providerInfo);
UserDetails details = new UserDetails(
userDetails.providerId,
userDetails.displayName,
userDetails.photoUrl,
userDetails.email,
providerData,
);
Navigator.push(
context,
new MaterialPageRoute(
builder: (context) => new Profile(detailsUser: details),
),
);
return userDetails;
}
有人可以告诉我是什么问题。

方法firebaseAuth.signInWithCredential(credential)
返回类型为AuthResult
的值,因此您需要执行以下操作:
AuthResult userDetails = await _firebaseAuth.signInWithCredential(credential);
另一种更好的选择是因为signInWithCredential
返回AuthResult
,并且由于类AuthResult
包含类型为user
的实例变量FirebaseUser
,那么您可以执行以下操作:
FirebaseUser userDetails = (await _firebaseAuth.signInWithCredential(credential)).user;

简单的解决方案(由类型更改引起):
Firebase最近将其类型“ FirebaseUser”(现已折旧)类型更改为“ User”。尝试在代码中重命名,这应该是解决方案。就我而言,它可以解决大多数相同的错误。
