[cloud_firestore] unable to retrieve data on Flutter Web

[Parmendrakumar]

I am unable to get data from firebase if using code line:
Firestore.instance.collection('testcrud').getDocuments();

But its working fine with
import 'package:firebase/firebase.dart' as fb;
fb.firebase.firestore().collection('testcrud').get();

pubspec.yaml:
cloud_firestore: ^0.12.9+6
firebase: any

On Mobile its revert situation.

I am working on master build

I am not sure about why this happening...

[yannbarrault]

Any news about this issue ? We would love to use this on flutter for web as well as on mobile version

flutter for web does not support plugins (like cloud_firestore package) yet,
there other solutions though
please look at this issue #1470 .

[Tonne-TM]

As plugins for flutter web were announced will cloud_firestore be updated too?

https://medium.com/flutter/web-support-for-flutter-goes-beta-35b64a1217c0

[Soumyadeep21]

Flutter for web is in beta now. So can we expect firebase packages like firestore for web as well?

You can subscribe to the issues mentioned in this project: https://github.com/flutter/flutter/projects/69

[ditman]

cloud_firestore web is being actively worked on right now.

I'm going to close this as we're tracking progress here: flutter/flutter#45293

Thanks for reporting!
