Flutterfire: [cloud_firestore] Blob fields parsed as GeoPoint
Bug report
Describe the bug
This is a reopen of issue #2020.
Although all my dependencies are up-to-date, I still have the problem : a Blob field seems to be parsed as a GeoPoint in profile and production mode.
!!! This bug only happens with flutter build web --profile and flutter build web --production. It does not happen with flutter run !!!
Steps to reproduce
I made a repository with a simple flutter app that reproduces the issue:
https://github.com/xurei/cloud_firestore_web_bug
import 'package:cloud_firestore/cloud_firestore.dart';
import 'package:firebase_auth/firebase_auth.dart';
import 'package:firebase_core/firebase_core.dart';
void main() async {
await Firebase.initializeApp();
await FirebaseAuth.instance.signInWithEmailAndPassword(
email: '[email protected]',
password: '123456789',
);
print('Authenticated');
final FirebaseFirestore firestoreClient = FirebaseFirestore.instance;
print('Querying firestore...');
final element = await firestoreClient.collection('items').doc('123456789').get();
print('Received document');
final payload = element.data()['Payload'];
print('Payload type:');
print(payload.runtimeType);
print('(should be Blob)');
}
You need a firestore document to fetch with a Blob field.
Expected behavior
The code should print a Blob type. With the current config, it shows GeoPoint.

Hi @xurei.
Unable to replicate ,we have example blob data in our test database which returns the following...
.
Could this potentially be invalid data?

@dackers86 I believe you used flutter run, which works. ("Performing hot restart...")
It's not when you do a flutter build web --profile and host the built files on a server.
I updated the issue description for better clarity.

@xurei @TahaTesser
Struggling to debug this one. My assumption is that a function cannot be properly read due to the minified version of the app.
Not sure how to debug this, open to suggestions on how to step through to see where the issue occurs?

@dackers86 I have no idea :-\ I never read this code.
Maybe by adding many print() between lines ?

Error: [cloud_firestore/unknown] Invalid argument (dartObject): Could not
convert: Instance of 'NativeJavaScriptObject'
Whenever I send a field of type GeoPoint to firestore for example:
final _position = GeoPoint(0,0)
store.collection('points').add({'position':_position});
This is very recent and only for web
