Firestore Database not updating (flutter/dart)

Question

I am unable to create collections in firebase..

I can see that the authentication table is being updated with the info being send. I can see that the storage table is being updated with the info being send. I don't see the firestore table being updated.

I am also seeing an error

Submission code::

  void _submitFormOnSignUp() async {
    final isValid = _signUpFormKey.currentState!.validate();
    if (isValid) {
      if (imageFile == null) {
        GlobalMethod.showErrorDialog(
            error: 'Please pick an image', ctx: context);
        return;
      }
      setState(() {
        _isLoading = true;
      });
      try {
        await _auth.createUserWithEmailAndPassword(
          email: _emailTextController.text.trim().toLowerCase(),
          password: _passTextController.text.trim(),
        );
        final User? user = _auth.currentUser;
        final _uid = user!.uid;
        final ref = FirebaseStorage.instance
            .ref()
            .child('userImages')
            .child(_uid + '.jpg');
        await ref.putFile(imageFile!);
        imageUrl = await ref.getDownloadURL();
        FirebaseFirestore.instance.collection('users').doc(_uid).set({
          'id': _uid,
          'name': _fullNameController.text,
          'email': _emailTextController.text,
          'userImage': imageUrl,
          'phoneNumber': _phoneNumberTextController.text,
          'location': _locationTextController,
          'createAt': Timestamp.now()
        });
        Navigator.canPop(context) ? Navigator.of(context) : null;
      } catch (error) {
        setState(() {
          _isLoading = false;
        });
        GlobalMethod.showErrorDialog(error: error.toString(), ctx: context);
      }
    }

    setState(() {
      _isLoading = false;
    });
  }

Answer 1

It's likely complaining about this line:

'location': _locationTextController,

You forgot to add .text like you did with the other fields.
