I have some mistakes with flutter and firebase, if someone can help would be great here is my auth controller
class AuthController extends GetxController {
final FirebaseAuth auth = FirebaseAuth.instance;
final Rxn<User> _firebaseUser = Rxn<User>();
Rx<XFile>? _pickedImage;
XFile? get profilePhoto => _pickedImage?.value;
// final user = FirebaseAuth.instance.currentUser.obs;
Rxn<User> get user => _firebaseUser;
// final user = FirebaseAuth.instance.currentUser;
@override
onInit() {
_firebaseUser.bindStream(auth.authStateChanges());
super.onInit();
}
// void register(
// String name, String email, String password, XFile? image) async {
// try {
// UserCredential _authResult = await auth.createUserWithEmailAndPassword(
// email: email.trim(), password: password);
// //create user in database.dart
// String downloadUrl = await uploadToStorage(image!);
// UserModel _user = UserModel(
// id: _authResult.user?.uid,
// name: name,
// email: _authResult.user?.email,
// profilePic: downloadUrl,
// );
// if (await Database().createNewUser(_user)) {
// Get.find<UserController>().user = _user;
// }
// } catch (e) {
// Get.snackbar(
// "Error creating Account",
// e.toString(),
// snackPosition: SnackPosition.BOTTOM,
// );
// }
// }
void register(
String name, String email, String password, XFile? image) async {
try {
if (name.isNotEmpty &&
email.isNotEmpty &&
password.isNotEmpty &&
image != null) {
// save out user to our ath and firebase firestore
UserCredential _authResult = await auth.createUserWithEmailAndPassword(
email: email,
password: password,
);
String downloadUrl = await uploadToStorage(image);
UserModel _user = UserModel(
id: _authResult.user?.uid,
name: name,
email: _authResult.user?.email,
profilePic: downloadUrl,
);
if (await Database().createNewUser(_user)) {
Get.find<UserController>().user = _user;
} else {
Get.snackbar(
'Error Creating Account',
'Please enter all the fields',
);
}
}
} catch (e) {
Get.snackbar(
'Error Creating Account',
e.toString(),
);
}
}
void login(String email, password) async {
try {
UserCredential _authResult = await auth.signInWithEmailAndPassword(
email: email.trim(), password: password);
Get.find<UserController>().user =
await Database().getUser(_authResult.user?.uid ?? '');
} catch (e) {
Get.snackbar("About User", "User message",
snackPosition: SnackPosition.BOTTOM,
titleText: Text("Acount creation failed"),
messageText:
Text(e.toString(), style: TextStyle(color: Colors.white)));
}
}
Future<void> signOut() async {
await auth.signOut();
Get.find<UserController>().clear();
}
Future pickImage() async {
print("call on click add photo icon");
final ImagePicker _picker = ImagePicker();
final XFile? pickedImage =
await _picker.pickImage(source: ImageSource.gallery);
print('picked image filled with image from gallery'); //This doesnt print at
if (pickedImage != null) {
Get.snackbar('Profile Picture',
'You have successfully selected your profile picture!');
// print(pickedImage.path);
}
_pickedImage = Rx<XFile>(pickedImage!);
// print(_pickedImage);
// print(profilePhoto);
}
// upload to firebase storage
Future<String> uploadToStorage(XFile? image) async {
Reference ref = FirebaseStorage.instance
.ref('')
.child('profilePics')
.child(auth.currentUser!.uid);
// print(ref);
UploadTask uploadTask = ref.putFile(File(image?.path ?? 'idemo'));
print(uploadTask);
// TaskSnapshot snap = await uploadTask;
String downloadUrl = await (await uploadTask).ref.getDownloadURL();
print(downloadUrl);
return downloadUrl;
}
}
Here is my function to createNewUser
class Database {
final FirebaseFirestore _firestore = FirebaseFirestore.instance;
Future<bool> createNewUser(UserModel user) async {
try {
await _firestore.collection("users").doc(user.id).set({
"name": user.name,
"email": user.email,
"profilePhoto": user.profilePic
});
return true;
} catch (e) {
print(e);
return false;
}
}
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. So if someone can help to fix this would be great!
