flutter app suddenly can't fetch data from firestore, Status{code=PERMISSION_DENIED, description=Missing or insufficient permissions., cause=null}

Question

I've been searching for a lot of problems that relate to this but I still didn't find the solution the error says

Accessing hidden method Ldalvik/system/CloseGuard;->warnIfOpen()V (greylist,core-platform-api, linking, allowed)

[WriteStream]: (26986c6) Stream closed with status: Status{code=PERMISSION_DENIED, description=Missing or insufficient permissions., cause=null}.

[Firestore]: Write failed at users/rX5LRztKddW1c8RIBqyNShligJV2: Status{code=PERMISSION_DENIED, description=Missing or insufficient permissions., cause=null}

[ERROR:flutter/lib/ui/ui_dart_state.cc(209)] Unhandled Exception: [cloud_firestore/permission-denied] The caller does not have permission to execute the specified operation.

and I've tried to change the firebase firestore rules in my console to be like this

service cloud.firestore {
match /databases/{database}/documents {
 match /{document=**} {
  allow read, write: if request.auth != null;
  }
 }
}

and after that still didn't affect anything. Usually I still can fetch data into a list and show in a gridview without having a user login. but now even when I log the user in it still didn't give me any of the data. been checking my dart code too and didn't find anything suspicious. tried to uninstall and install it back. nope, didnt works too.

Answer 1

I Resolve the problem by Un-enforced the app check on the firebase console. by doing this

 Project Settings > App-Check > APIs > Cloud Firestore click UnEnforce.

but in my case it still won't work. and i try to disconnect the flutter app with the firebase console and create a new one without connecting the app-check feature, and it work properly now
