[英]Error: The getter 'documents' isn't defined for the class 'Object'
[英]The getter 'documents' isn't defined for the type 'QuerySnapshot' error in Flutter Firebase
所以我想在 flutter 中对我的应用程序实施基于角色的身份验证。 只有具有权限的用户才能访问此站点。 我收到错误:
The getter 'documents' isn't defined for the type 'QuerySnapshot<Map<String, dynamic>>'.
Try importing the library that defines 'documents', correcting the name to the name of an existing getter, or defining a getter or field named 'documents'.
有人可以在这里帮助我吗?
代码:
class AutoLoginHandler extends StatelessWidget {
@override
authorizeAccess(BuildContext context) {
FirebaseAuth.instance.currentUser!().then((user) {
FirebaseFirestore.instance
.collection('/users')
.where('uid', isEqualTo: user.uid)
.get()
.then((docs) {
if (docs.documents[0].data.exists) {
if (docs.documents[0].data['role'] == 'admin') {
Navigator.of(context).push(new MaterialPageRoute(
builder: (BuildContext context) => new LehrerMainPage()));
}
}
});
});
}
}
尝试这个。 但我建议您用于角色管理访问始终使用Custom Claims 。
.then((results) {
if (results.size > 0) {
if (results.docs[0].data()['role'] == 'admin')
{
Navigator.of(context).push(new
MaterialPageRoute(
builder: (BuildContext context) => new
LehrerMainPage()));
}
}
}
