I am able to pass the name, address, password, and email, but the url is "", how can I pass the image url next to the email and address data? If anyone can help, I would appreciate it very much !! I have a class called User Model and a SignUp.
String userImageUrl = "";
static final String userAvatarUrl = 'url';
final picker = ImagePicker();
PickedFile _imageFile;
if (_formkey.currentState.validate()) {
Map<String, dynamic> userData = {
// "uid": model.firebaseUser.uid,
"name": _nameController.text,
"email": _emailController.text,
"address": _addressController.text,
"url": userImageUrl,
};
model.signUp(
userData: userData,
pass: _passController.text,
onSucess: _onSucess,
onFail: _onFail,
);
}
uploadAndSaveImage();
uploadToStorage();
Future uploadToStorage() async {
showDialog(
context: context,
builder: (c) {
return LoadingAlertDialog(
message: "Autentificando, Por favor espere...",
);
});
String imageFileName = DateTime.now().millisecondsSinceEpoch.toString();
Reference reference = FirebaseStorage.instance.ref().child(imageFileName);
UploadTask task = reference.putFile(File(_imageFile.path));
await (await task).ref.getDownloadURL().then((urlImage) {
urlImage = userImageUrl;
class UserModel extends Model {
Future<Null> _saveUserData(Map<String, dynamic> userData) async {
this.userData = userData;
await FirebaseFirestore.instance
.collection('users')
.doc(firebaseUser.uid)
.set(userData);
}
}

Here is my function to createNewUser

Here is HomeController
class HomeController extends GetxController {
final Rxn<List<TodoModel>> todoList = Rxn<List<TodoModel>>([]);
var selectedDate = DateTime.now().obs;
List<TodoModel>? get todos => todoList.value;
#override
void onInit() {
super.onInit();
String? uid = Get.find<AuthController>().auth.currentUser?.uid ?? '';
print(uid);
todoList.bindStream(Database().todoStream(uid));
}
chooseDate() async {
DateTime? pickedDate = await showDatePicker(
context: Get.context!,
initialDate: selectedDate.value,
firstDate: DateTime(2000),
lastDate: DateTime(2024),
//initialEntryMode: DatePickerEntryMode.input,
// initialDatePickerMode: DatePickerMode.year,
);
if (pickedDate != null && pickedDate != selectedDate.value) {
selectedDate.value = pickedDate;
}
}
}
and here is View page
GetX<HomeController>(
init: Get.put<HomeController>(HomeController()),
builder: (HomeController todoController) {
if (todoController.todos != null) {
// print(todoController.todos?.done ?? false);
return Expanded(
child: ListView.builder(
itemCount: todoController.todos?.length,
itemBuilder: (_, index) {
return TodoCard(
uid: controller.user.value?.uid ?? '',
todo: todoController.todos![index],
);
},
),
);
} else {
return Text("loading...");
}
},
),
So, I have an error when I register a new user I got this error:
The following assertion was thrown building Builder(dirty):
a document path must be a non-empty string
Failed assertion: line 116 pos 14: ‘path.isNotEmpty’
And here is output from terminal:
The relevant error-causing widget was
GetMaterialApp
lib/main.dart:23
When the exception was thrown, this was the stack
#2 _JsonCollectionReference.doc
#3 Database.todoStream
#4 HomeController.onInit
#5 GetLifeCycleBase._onStart
#6 InternalFinalCallback.call
#7 GetInstance._startController
#8 GetInstance._initDependencies
#9 GetInstance.find
#10 GetInstance.put
#11 Inst.put
So a problem is with this path, and when I reload from the visual studio I god the right user with the right data. So the problem is when I register a user for the first time.
It looks like uid is empty, which you should also be able to see from looking up print(uid); in your output.
When your application or web page loads, Firebase automatically tries to restore the previously signed in user from its local state. This requires that it makes a call to the server however (for example to check if the account has been disabled) and while that call is going on, your main code continues to execute and the currentUser variable is going to be null.
Your code needs to take this into account. The easiest way to do this is to not depend on currentUser, but instead to use an reactively respond to changes in the authentication state as shown in the first example in the documentation on getting the current user:
FirebaseAuth.instance
.authStateChanges()
.listen((User? user) {
if (user != null) {
print(user.uid);
}
});
The authStateChange method here returns a stream that fires an event whenever the authentication state changes, so when the user signs in or signs out. The common way to use this stream is to either set the user to the state of your widget, or to use the stream directly in a StreamBuilder.
When I create a new user the error (_CastError (type 'Null' is not a subtype of type 'Map<String, dynamic>' in type cast)) apears at User.fromSnap ...as Map<stringm,dynamic> and firebase creates the user auth but not the user data
Can you help me to add array of array of objects to firebase?
Thanks!

Your factory looks right. But you're sending it nothing...the snap is null is what that error is telling you.
I am new to flutter. So Please kindly bear with me.
I am creating a Real Estate App using Firebase and Provider.
I have two root Collections (1) "users" and (2) "properties"
I would like to achieve one specific task.
Although it seems like a simple task, yet I am still unable to solve it.
The task is to store Firebase User UID as Firestore Document ID of the rool Collection called "users" when the user sign up.
The problem I am having is the Firestore Document ID is automatically generated and its not Firebase User UID. Plus the field for userId appears null in Firestore.
Please see the screenshot of my database here
Thank you for your attention and time.

}
}
After login/signup successfully you can get user id from FirebaseAuth.instance.currentUser?.uid
The method 'document' isn't defined for the type 'CollectionReference'.
Try correcting the name to the name of an existing method, or defining a method named 'document'.

I want user in my app to stay logged in. I'm using the firebase authentification with IDToken which lasts for 1hour until it expires. I want to auto refresh the session everytime if it is going to expire.
what Ive read so far here https://firebase.google.com/docs/reference/rest/auth/#section-refresh-token it should be somehow possible with https://securetoken.googleapis.com/v1/token?key=[API_KEY]

how to modify my auth.dart to achieve the auto refreshing?
EDIT:
As mentioned in the comments, im working with providers where I have the following functions to retrieve the token:
update(String token, id, List<items> itemsList) {
authToken = token;
userId = id;
}
also in every of my API calls im using the auth parameter already:
var url = 'https://test45.firebaseio.com/folder/$inside/$ym.json?auth=$authToken';
I just need somebody who can show me how to modify my code with the refresh token.
Thanks in advance!
EDIT:
I tried to implement it, but im getting an infinite loop, please help:
String get token {
if (_expiryDate != null &&
_expiryDate.isAfter(DateTime.now()) &&
_token != null) {
return _token;
}
refreshSession();
}
Future<void> refreshSession() async {

body: json.encode({
'token_type': 'Bearer',
}));
final responseData = json.decode(response.body);
if (responseData['error'] != null) {
throw HttpException(responseData['error']['message']);
}
_token = responseData['id_token'];
_userId = responseData['user_id'];
_expiryDate = DateTime.now().add(Duration(seconds: int.parse(responseData['expires_in'])));
_autoLogout();
notifyListeners();
final prefs = await SharedPreferences.getInstance();
final userData = json.encode({

'expiryDate': _expiryDate.toIso8601String(),
});
prefs.setString('userData', userData);
} catch (error) {
throw error;
}
}
I edited your refresh_token() function.
Firstly, you should use your web api key on your firebase project with the link. You should also save the refresh token. And if you post like this, it will work. If don't work, try without json.encode() function on your body as I commit.
Future<void> refreshSession() async {
final url =
'https://securetoken.googleapis.com/v1/token?key=$WEB_API_KEY';
//$WEB_API_KEY=> You should write your web api key on your firebase project.
try {
final response = await http.post(
url,
headers: {
"Accept": "application/json",
"Content-Type": "application/x-www-form-urlencoded"
},
body: json.encode({
'grant_type': 'refresh_token',
'refresh_token': '[REFRESH_TOKEN]', // Your refresh token.
}),
// Or try without json.encode.
// Like this:
// body: {
// 'grant_type': 'refresh_token',
// 'refresh_token': '[REFRESH_TOKEN]',
// },
);
final responseData = json.decode(response.body);
if (responseData['error'] != null) {
throw HttpException(responseData['error']['message']);
}
_token = responseData['id_token'];
_refresh_token = responseData['refresh_token']; // Also save your refresh token
_userId = responseData['user_id'];
_expiryDate = DateTime.now()
.add(Duration(seconds: int.parse(responseData['expires_in'])));
_autoLogout();
notifyListeners();
final prefs = await SharedPreferences.getInstance();
final userData = json.encode({
'token': _token,
'refresh_token': _refresh_token,
'userId': _userId,
'expiryDate': _expiryDate.toIso8601String(),
});
prefs.setString('userData', userData);

You need to save the refresh token.
Follow this topic to refresh your IDToken using the refresh token: https://firebase.google.com/docs/reference/rest/auth#section-refresh-token
When making any calls to the API, use a function to retrieve the IDToken. This function must check if the current IDToken is still valid and, if not, ask for a new one (using the link provided).
I think the Dio library is right for you
dio = Dio();
dio.options.baseUrl = URL_API_PROD;
dio.interceptors.add(InterceptorsWrapper(
onRequest: (Options option) async{
//getToken() : you can check token expires and renew in this function
await getToken().then((result) {
token = result;
});
option.headers = {
"Authorization": "Bearer $token"
};
}
));
Response response = await dio.get('/api/users');
body expects string...Hence change body in refreshSession() to body: 'grant_type=refresh_token&refresh_token=[YOUR REFRESH TOKEN]',.
You need to load 'refreshToken' from SharedPreferences before sending http.post request.
