'Firestore-Flutter-GetX: How to get document id to update a record in Firestore
I am very new to Dart, and coding in general. I have produced this code after watching tutorials on YouTube. For the most part, I have been able to troubleshoot most of my problems on my own, yet I cannot figure out my most recent errors. I was successful to create record in firestorm but I am unable to update it because I am not able to get Doc ID.
Here is my code:-
import 'package:flutter/material.dart';
import 'package:lms_definer/controllers/profileController.dart';
import 'package:lms_definer/controllers/textController.dart';
import 'package:get/get.dart';
import 'package:lms_definer/model/profileModel.dart';
import 'package:lms_definer/constants/constants.dart';
import 'package:cloud_firestore/cloud_firestore.dart';
import '../helper/firestore_db.dart';
class EditProfile extends StatelessWidget {
const EditProfile({Key? key}) : super(key: key);
@override
Widget build(BuildContext context) {
var _textController = ProfileEdit();
return Scaffold(
body: GetX<ProfileController>(
init: Get.put<ProfileController>(ProfileController()),
builder: (ProfileController profileController) {
return Container(
child: ListView.builder(
itemCount: profileController.profiles.length,
itemBuilder: (BuildContext context, int i) {
final _profileModel = profileController.profiles[i];
setTextEditControllerValue(_textController, _profileModel);
return SafeArea(
child: Container(
padding: EdgeInsets.all(20),
child: Form(
child: Column(
children: [

}),

},
));
}
ProfileModel profileModelVal(ProfileEdit _textController) {
final profileModel = ProfileModel(
firstName:
_textController.fNameController.text.trim(),
lastName:
_textController.lNameController.text.trim(),
parentName: _textController
.fatherNameController.text
.trim(),
phoneNumber:
_textController.phoneController.text.trim(),
address:
_textController.adressController.text.trim(),
schoolName:
_textController.sclNameController.text.trim(),
stdClass: _textController.stdClassController.text
.trim());
return profileModel;
}
void setTextEditControllerValue(ProfileEdit _textController,
ProfileModel _profileModel) {
_textController.fNameController.value =
TextEditingValue(text: _profileModel.firstName);
_textController.lNameController.value =
TextEditingValue(text: _profileModel.lastName);
_textController.fatherNameController.value =

_textController.fatherNameController.clear();
_textController.adressController.clear();

MY Database file:-
import 'package:cloud_firestore/cloud_firestore.dart';
import 'package:flutter/cupertino.dart';
import 'package:lms_definer/constants/constants.dart';
import 'package:lms_definer/model/profileModel.dart';
class FirestoreDb {
static createProfile(ProfileModel profilemodel) async {
await firebaseFirestore.collection('users').doc(auth.currentUser!.uid)
.collection('profile')
.add({
'firstName': profilemodel.firstName,
'lastName': profilemodel.lastName,
'parentName': profilemodel.parentName,
'phoneNumber': profilemodel.phoneNumber,

}
static Stream<List<ProfileModel>> profileStream() {
return firebaseFirestore
.collection('users')
.doc(auth.currentUser!.uid)
.collection('profile')
.snapshots()
.map((QuerySnapshot query) {
List<ProfileModel> profiles = [];
for (var profile in query.docs) {
final profileModel =
ProfileModel.fromDocmentSnapshot(documentSnapshot: profile);
profiles.add(profileModel);
}
return profiles;
});
}
static updateProfile(ProfileModel profilemodel, documentId ) {
firebaseFirestore
.collection('users')
.doc(auth.currentUser!.uid)
.collection('profile')
.doc(documentId)
.update(
{
'firstName': profilemodel.firstName,
'lastName': profilemodel.lastName,

'phoneNumber': profilemodel.phoneNumber,
'address': profilemodel.address,
'schoolName': profilemodel.schoolName,

'createdOn': Timestamp.now(),
}
);
}
static deleteProfile(String documentID) {
firebaseFirestore.collection('users').doc(auth.currentUser!.uid).collection(
'profile').doc(documentID).delete();
}}
I need doc Id to update the file. Please help. Thank you
Solution 1:[1]
static updateProfile(ProfileModel profilemodel, documentId ) {
firebaseFirestore
.collection('users')
.doc(auth.currentUser!.uid)
.collection('profile')
.get()
.then((QuerySnapshot querySnapshot) {
final docId = queryShapchot.docs.first.id;
firebaseFirestore
.collection('users')
.doc(auth.currentUser!.uid)
.collection('profile')
.doc(docId)
.update({
// Add data here
})
});
}
This should do the trick for you.

Once the user is logged in (I'm assuming the EditProfile page is only visible to logged in users) you should store the userId somewhere. This can be done using flutter_secure_storage or using an auth library like FirebaseAuth.
Then when you want to update the doc of the user, you can get the userId which was stored before to update the doc.
