[cloud_firestore] Sync failed when closing app

[PrismaSoftGC]

Sync failed when closing app

Every time I enter a bank information, I need to check if the name is correct, because I want this feature to work offline, so I can not have inconsistencies in the bank. So far as the code below is working the way I want. but in only one situation does the sync fail, which is when I press the app's back button until it closes. So when I turn on the internet the data is not synchronized.

Code :

  Firestore.instance
      .collection('Regiao')
      .where('idRegiao', isEqualTo: idRegiao)
      .snapshots()
      .listen((data){
        data.documents.forEach((doc) {

          Firestore.instance
            .collection('CadernoCampoDefensivo')
            .document(idCadernoCampo)
            .updateData({'regiao' : doc['nomeRegiao']})
            .then((_){});


        });
  });

Log Error:

@kroikie Have you encountered this problem?

Hi @PrismaSoftGC
can you please provide your updated flutter doctor -v?
Also, to better address the issue, would be helpful
if you could post a self contained app on github
or the steps to reproduce it.
Thank you

So unfortunately I can't post an app to gitHub because it's a commercial project, but it's a pretty simple operation. When I am offline I need to record information, and before that I search another collection to be able to save updated. Very well, I save the operation, and when I turn on the internet the data is synchronized as expected. But if I press back on the application until it closes, this synchronization fails terribly.

PS: Sorry for english because i am brazilian and i am using google translator

@PrismaSoftGC I have not seen this; are you able to reproduce this behavior with the example app for cloud_firestore?

[iapicca]

Without additional information, we are unfortunately not sure how to resolve this issue. We are therefore reluctantly going to close this bug for now. Please don't hesitate to comment on the bug if you have any more information for us; we will reopen it right away!
Thanks for your contribution.

Could everyone who still has this problem please file a new issue with the exact descriptions what happens, logs and the output of 'flutter doctor -v' please.
All system setups can be slightly different so its always better to open new issues and reference related issues.
